3 years after your video but THANK YOU for the clear pump/filter details but ESPECIALLY the gasket repositioning for the cap flange and tank body join. My goodness it was so easy. Brilliant. Thanks to you replacing the original blown tube between pump and filter was a doddle. I have a 98 900SS ie. Got it 8/23 and it went kaput . Traced issue to tank and sure enough a split hose. Thanks a heap ❤ you saved a lot of stress time and fuming😂❤
I'm so happy I found this Video! My Monster 750 quit running at a Stop Sign the other day and I have been trying to diagnose it. Turns out the hose between the Fuel Pump and Fuel filter had fallen off! I wouldn't have ever found the issue if I hadn't seen this video and how to reach inside to troubleshoot! Thank you!
I think the piece you describe as a baffle actually fits onto the bottom of the filler neck. The tank setup is similar to my supersport. Having watched your vid, I'm about to pull the filler neck out of mine to change the fuel filter. The bike was left for a couple of years with fuel in it and now I have to clean all the sludge out of it. My fault unfortunately. ;)
Great video! Just one thing, the piece that you found at the bottom of the tank, in reality, is the tank sleeve, which you can find for reference on the diagram of the monster 900 (year 2000)
Thank you so much! This video gave me the courage to dive in and try to fix the bike on my own. My problem was bad battery and bad fuse. I’m glad I didn’t have to deal with the fuel pump.
Well done👍… What a calm and level headed repair job! I think this is the problem on my ‘01 S4 that’s been sitting for 8 yrs. New battery and fuel, but just cranks. I have trouble reaching into the tank - too tight. You make it look easy😉. Cheers! [Edit] : The part of your clip where you commented on cycling the ignition key to prime air out of the fuel pump… I just needed to do that 5-6 more time to clear the “air bubbles.” It started (after 8 yrs!)… new battery, fresh gas, bleeding clutch line, new airbox clips, and some clean up!
Awesome tip on replacing the rubber flange around the fuel cap. Glad I saw this first before finishing my fuel tank cleanout / fuel pump replacement on my 1995 900SS/CR
Thank you, changed my fuel filter on my m800. The rubber bit was tricky to seal back on the fuel cap housing, got a spare pair of hands to help at that point.
What a goldmine, I've got an intermittent fault in my pump, I was going to take it to the shop to get it fixed but now I think I'll do it myself, thanks 👍
This is David. David is picking up his first Ducati today or tomorrow; a 1999 ST4 that hasn't run in 2 years. LOL... (Trying to mimic your cute introduction!) I'm aware that the ST4 fuel pump arrangement is substantially different from this, but I found your video superbly done, Your thought processes and procedures exquisitely explained, and the editing first rate. And, pretty sweet trick about the fuel filler flange/gasket! Thanks so much for taking the time and effort to make and post this video.

Yo man I just want to take the time to say I can’t thank you enough for a great explanation on this video my bike randomly stopped cranked so I went and replaced fuel pump and fuel filter turned the keg few times just like you did to get air out of lines and finally started right up after 2 weeks of trouble shooting
Hey, I'm really glad it worked out for you! Here's another tip you might want to do just as preventative maintenance. I've come across 2 Ducati in the last 6 months with issues where the engine will randomly die. These are really hard to diagnose because you can't reliably duplicate the problem. Sometimes they start right back up again and run fine for days. Apparently it's a super common issue. There's a fuel pump relay that's very common problem. Just look up Omron G8HL-H71 on Amazon. They're $9 for two relays. Perfect because the bike has 2 relays this size. Replace them both. This fixed the problem on both bikes. One of them had been randomly dying for years and and finally completely died. So, I was able to catch the relay failure.
Very informative video. Hope I don't need it for my 2002 monster 900IE. It still runs fine, but 20 years... I can imagine I''ll encounter this problem some day.
My m750 had starting problems sometimes. It would run with starter spray ok. Eventually I discovered that the fuel hose had a small leak for a long time (when it became a big leak and tank emptied on the pavement overnight). Before that if I did not ride for a few days, the fuel in the hose become empty and the mechanical pump would not work propely. I replaced the fuel hose, measured with the original that it's the same (mistake!) and put things back together. The problem was that the original fuel hose is kind of molded in shape, while the one I bought would sometimes bend over itself and then I would have fueling issues. If I took the tank up and examined the problem, fuel hose would straighten up and work... it was all luck if it went properly in place or not. That took a while to diagnose. Unfortunately the bike had other physical damages and I sold it since replacing the frame would not be feasible.
@@redneckoriental Thanks to your video I have already confirmed that the pump is good by applying 12V to it.....

Hey man. I have a ducati monster 750 cc. What if the ignitation fuse is burned everytime I turn on the keys only? The bike won't start. No sound nothing. Only a burning ignition fuse.
Can I ask you? What do you use to clean the fuel pump because I just got Ducati 620 monster and I have the same problem and I would like to just clean the filter and the fuel pump so I would like to know what liquids cleaners do you use?
Hello friend, how are you? Look, I have my ducati monster just like yours, but mine activated the immobilizer system and that won't let it start, what can I do? thanks
It was a short explanation in the video. That strainer sock tends to deteriorate and fall apart, as this one did. The system already has a fuel filter to protect the injectors. The sock just keeps large particles greater than the size of sand from entering the pump. I've never found rocks at the bottom of a motorcycle fuel tank. So, I don't think the sock is necessary.
Love the video. I have the same issue and bike. Trying to find a replacement fuel pump and the filter. Dealer wants $1,228! Can you let me know or send me the links for the two items?
Here's someone selling the fuel pump in eB www.ebay.com/itm/173883408497. Here's the Wix fuel filter: www.amazon.com/gp/product/B000C9WJBM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. Here's the fuel hose (get 2 if you plan to replace both in-tank hoses): www.amazon.com/gp/product/B001R5XSGU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1.
I have a Ducati Monster 900 with a hard start, I paid a shop to diagnose and fix it, they did a $2000 topend rebuild but the exact problem remains. Is that something you might be interested in taking a look at?
First, find out if it's lack of spark or fuel that's causing the hard start. Remove the air filter. Spray carb cleaner or brake cleaner into the intake for 2 or 3 seconds and crank the engine. If it wants to start right away instead of the usual hard start, you know you have a fuel problem. If it's a fuel problem, you may want to start by replacing the 2 relays. They're cheap. Look up "GH8L-H71 Relay" on Amazon. If these look like your relays, replace them. Otherwise, do like in the video and check for power to the fuel pump while cranking. Where are you located?
@@tychormthorp Cheapie one with a light bulb inside. You can get one from Harbor Freight tools if you have one nearby. Otherwise I think mkst auto parts stores sell them.
@@redneckoriental The bike is actually capable of starting, but it's a hard start that will stall and die after 3-5 seconds, even with the fast idle on. Both of the headers were warm after attempting to start a couple times, and I was getting a burning/fuel smell from the right pipe for some reason (even though they meet in the middle before splitting off to each tailpipe?). If I give it any throttle while cranked it will almost immediately stall. I recall the previous owner mentioned something about fuel pump issues and finding pieces of the sock in the tank, and I suspect he may have never properly cleaned it out. Last year I put it in a heated garage and dumped a bottle of injector cleaner / stabilizer into the tank, and there's ethanol added to the 91 up here so I suspect the fuel is muck with bits of broken sock and gunk by now. I pulled the plugs and they were black as night (not blued, everything from the gasket up to the electrode was thoroughly fouled). Would you mind if I sent you pics / video? Might make things less abstract. I started in on it this week! So far I've; 1) Verified spark with a bulb tester, looks consistent. ______________________________________________________________________________________________________________________________________________________________________ 2) Verified battery is making ~12v and appears to be in spec when checked with a load tester. That being said when I turn my ignition on, a multimeter indicates the battery is producing 10v, and when I attempt to crank it the voltage drops to ~ 7-8v - I had the battery tested at two different shops in town and the folks there said it seems perfectly fine but could we be missing something? ______________________________________________________________________________________________________________________________________________________________________ 3) Replaced the fouled plugs, the bike seems more willing to start and idle is slightly more healthy but still has issues w/ idle rpm slowly dropping then stalling. ______________________________________________________________________________________________________________________________________________________________________ 4) I have checked the fuses, ordered the relays ______________________________________________________________________________________________________________________________________________________________________ I will drain the tank and check the tank / pump for debris while I do - like I mentioned above I suspect the fuel in the bike is sludge and am curious to see if fresh starts it. I'll comment again after I've changed fuel/verified pump, filter/installed new relays. Will also spray some carb cleaner into the intake to see if it starts more easily. Thanks so much for the helpful advice so far, I can't wait to get back on the road!
8:39 I found this sleeve also, and it doesn't look like it fits on the gas pump. Have you considered it being meant for the filter so it doesn't rub against the inner walls of the tank? I happen to have 2 tanks and while the replacement one has claws to hold the filter in place the original tanks doesn't. I will try and see if it fits :-)
I've figured it out! It's a sleeve for the pump nozzle when you're gassing up. You should've connected it to the bottom of tank cap. Part 802.1.005.1A (they call it just "hose") parts.powermotorcyclesusa.com/p/Ducati__/Hose/42747804/802.1.005.1A.html
Hi there, I ended up here on your video because I think my fuel pump is also on its way out on my 04 monster 620. It started acting weird after short trips, stalling on my and dying then not wanting to start. Last time it did it when I turned the key to on the fuel pump or something made a loud clicking noise and the bike wouldn’t start then I let it alone for a few minutes and the pump would whine and prime normall for the 2 seconds or so and the bike would turn on fine and run for a few minutes then die again and the priming period was another loud clicking instead of the usual whine and prime and bike wouldn’t start then I’d let it alone and it’ll prime fine and start gain but can’t ride long without the bike gasping for gas and making loud explosions. It had been running just fine before I parked it for winter. Any help or ideas?
Your problem is is harder to pinpoint because it's intermittent. Normally, you'd check for power to the fuel pump when it's supposed to be be on, like during priming. If you have power, but the pump doesn't run, then you have a pump problem. If you have no power when there's supposed to be power, the problem is somewhere upstream. A cheap thing to eliminate would be the fuel pump relay. This is a high failure item. There are 2 relays. I don't remember if they both affect the fuel pump, but I replace them both anyway because they're cheap. You can find them on Amazon for $9. Search for "g8hl-h71". Stick to a good brand, like Omron or Bosch. There is a way to bypass the relay with a jumper wire if you want to do this before buying the relays. If you look at the relay, there are 4 pins. Google the "g8hl-h71", go to images and look at a diagram of this relay. Pins 3 and 5 are the ones that need to connect when the relay is on. Remove the relays from the bike On the sockets for the relays, install a jumper wire to connect 3 and 5. Do this for both relays.
@@redneckoriental so all the relays and fuses look good and in great shape, nothing corroded or burn and everything is clean. I replaced the two relays since they’re were cheap and bike still runs fine but sometimes I can hear the pump inside the tank while cap is open it’s kind of sputters and clicks when priming. I got a new pump and fuel filter too. Now my question is how do you take off the old pump? I can see it at the bottom of the tank but don’t want to pull or twist anything and damage something.
@@Leona31007 It does sound like your fuel pump is going bad then. If you have a steel tank, like the one in the video, just pull on the pump and it will come out. It just slides into a rubber sleeve. There are no fasteners holding it on.
Awesome tutorial! I was smacking the fuel flange with a rubber hammer and thought, this can't be right?!? Your the best man! thx for the tip.

I put the part numbers in the description of the video. Please diagnose it before you throw money at it.
I think it is one of the first 620ie, is it right?? model year?
you slide the pump into the rubber sleeve but you dint put the fuel strained at the end of the fuel pump why?
It was a short explanation in the video. That strainer sock tends to deteriorate and fall apart, as this one did. The system already has a fuel filter to protect the injectors.

8:39 I found this sleeve also, and it doesn't look like it fits on the gas pump. Have you considered it being meant for the filter so it doesn't rub against the inner walls of the tank? I happen to have 2 tanks and while the replacement one has claws to hold the filter in place the original tanks doesn't. I will try and see if it fits :-)
I've figured it out! It's a sleeve for the pump nozzle when you're gassing up. You should've connected it to the bottom of tank cap. Part 802.1.005.1A (they call it just "hose") parts.powermotorcyclesusa.com/p/Ducati__/Hose/42747804/802.1.005.1A.html
@@IanSampaio Great find! I'll have to reach in there and grab it.
What year is that bike??
Great video ! can you please include a link for the parts? I have the exact same issue
I just updated the video description with links to where you can buy the pump, filter and hoses.
@@redneckorientalcan you please include the link for the parts. Pomp and filter please. I am need need

@@redneckoriental yes ser. Thaks
personally, I would have put a new screen on the pump.
Please come fix my 05 monster
Hi there, I ended up here on your video because I think my fuel pump is also on its way out on my 04 monster 620. It started acting weird after short trips, stalling on my and dying then not wanting to start. Last time it did it when I turned the key to on the fuel pump or something made a loud clicking noise and the bike wouldn’t start then I let it alone for a few minutes and the pump would whine and prime normall for the 2 seconds or so and the bike would turn on fine and run for a few minutes then die again and the priming period was another loud clicking instead of the usual whine and prime and bike wouldn’t start then I’d let it alone and it’ll prime fine and start gain but can’t ride long without the bike gasping for gas and making loud explosions. It had been running just fine before I parked it for winter. Any help or ideas?
Your problem is is harder to pinpoint because it's intermittent. Normally, you'd check for power to the fuel pump when it's supposed to be be on, like during priming. If you have power, but the pump doesn't run, then you have a pump problem. If you have no power when there's supposed to be power, the problem is somewhere upstream. A cheap thing to eliminate would be the fuel pump relay. This is a high failure item. There are 2 relays. I don't remember if they both affect the fuel pump, but I replace them both anyway because they're cheap. You can find them on Amazon for $9. Search for "g8hl-h71". Stick to a good brand, like Omron or Bosch. There is a way to bypass the relay with a jumper wire if you want to do this before buying the relays. If you look at the relay, there are 4 pins. Google the "g8hl-h71", go to images and look at a diagram of this relay. Pins 3 and 5 are the ones that need to connect when the relay is on. Remove the relays from the bike On the sockets for the relays, install a jumper wire to connect 3 and 5. Do this for both relays.
@@redneckoriental so all the relays and fuses look good and in great shape, nothing corroded or burn and everything is clean. I replaced the two relays since they’re were cheap and bike still runs fine but sometimes I can hear the pump inside the tank while cap is open it’s kind of sputters and clicks when priming. I got a new pump and fuel filter too. Now my question is how do you take off the old pump? I can see it at the bottom of the tank but don’t want to pull or twist anything and damage something.
@@Leona31007 It does sound like your fuel pump is going bad then. If you have a steel tank, like the one in the video, just pull on the pump and it will come out. It just slides into a rubber sleeve. There are no fasteners holding it on.
