thank you! You just saved me a big repair bill. My mower would start but only roll a foot or two and die out like it wasn't getting gas. Opened the hood and saw a tiny tear in the tube. Touched it to verify that was what I was seeing and it tore more. Really tender. Waiting for the mail to drop the tube off any minute now. While I'm at it I'll change the fuel pump and filter too. Mine is an older D130 but essentially the same. The repair shop would have charged me $135 an hour plus travel time and parts so I could have been nailed for nearly $300 for a very simple thing.
Dude you just saved my mind from “future” frustration. I never checked that little hose. I have changed out the fuel pump. I think I did that like 3 years ago. But I do change out the fuel filter once a year. All of these components are cheap to replace. THANK YOU.
I have been trying to help my Dad get his lawnmower JD D130 and you found my problem. Thank you. Well I found crack in vacuum line, will go get new pump and line.
@@MowerMike he has dementia and is all about mowing and I have had such a hard time with this mower. I have to say, every video I watched (mower kept stalling) never mentioned vacuum line. Again, Thank you so much.
@@MowerMike well.....mower stayed running a bit longer but continues to stall long before I can even engage blades. I have tuned up mower before replace vacuum hose. I think I should clean carburetor, which I haven't done before. If that doesn't work, I don't know what to do, but I am stubborn enough to keep trying. If you have any ideas, I would be appreciative.
i took my gas tank out thinking it was cloged bought a new gas cap blew out all the hoses put a new pump on never knew i had a vacum hose thank you thank you thank you
Hey man I really appreciate the comment. These videos take work but are fun. 3 Acres! Time to upgrade to a zero turn. I will be get into some zero turn videos once I finish the Deere series.
Thank You! You! , Thank You! , !!!!! I have been restoring a 20 yo generator. I began to suspect a fuel pump problem but your video just said replace the lines and the pump!! $30 using your affiliate links. I probably just bought you your next postage stamp!!! I am betting this will go a long way to solving the problem!
This looks like the right one. When replacing the tank I suggest finding a way to bend up the sheet metal above the tank and just slide it in there vs taking the mower apart. Be careful! amzn.to/4f0lcAv
I also have an LA145 and it has been hard to start. I have since replaced the fuel pump and this vacuum hose. While I was at it, I replaced the fuel filter, and spark plugs too. Of course after doing so the mower did take about 20~30 or cranking (far, far less time starting than prior to replacing the parts) before it started. Then a week went by and I try to start it up again and the struggle is real. Several attempts of cranking (4 to 6 times of long periods of cranking) before it finally started (runs great). Yes, the choke was one during initial start. I testing the fuel flow while cranking and I see fuel is pumping. Would you do a video of cleaning the carbonator on a LA145?
Yep I will do one eventually. But in that engine it is easier to just replace the carb they are cheap on Amazon. I suggest checking your valve clearances first though.
Check out my Briggs playlist. I am sure I have something. But if it is a newer one with the plastic inside the carb you are better off just buying a cheapo new one on Amazon
Sounds like that head is getting way too hot. Sometimes grass gets built up under the cover and in the engine fins. You may take the plastic piece off ant give it a pressure washing to blow all the crud off the motor
I have a similar situation. When I replaced the vacuum hose I did not destit properly it was getting dark and pushed the seating part all the way through . It appears to be tight but not seated properly will it work. I will try in the morning. I replac the straight tube cause it was dangling with hole wide open. It probably has some dirt in there as well.
Mine has a 17.5 briggs buy oil is going to the screen of the fuel pump I adjusted the valves new gasket and still it oil seeps out would it be the fuel pump?
My guess is the crank case is pressurized because the rings are worn out and causing oil to push through the tube on the valve cover. Or maybe you just have overfilled it with oil.
I'm going to clean the carburetor, i didn't have any fuel in my line when i replaced my fuel filter..I hate having to replaced these parts with other bad parts😔
Thanks for this,my mower only has 40 hrs on it,I'm changing the fuel pump out now. I have no help and little $$ so here I go. 26.99 is what I just paid in 2024. Again, thanks for your video. Nope, must not be the pump still won't start
Is it possible that the pump is somehow restricting the vaccum and the engine start burning oil? My engine runs goods but when I started it for the first time after the winter it started burning oil and it was spitting oil from there. Please help me
My JD 102 has a long vacuum hose coming from engine. There is no small elbow tube like you show here. But I also have no vacuum coming from engine to run the fuel pump.
The long line is probably going from the engine to the fuel tank is just a breather line. If you are not getting fuel pumping I suggest a new fuel pump
I have a z345r with 22hp. When I take off hose from valve cover at fuel pump there is back pressure coming out of the hose. There is also oil residue at top of oil fill and drain, leaks at oil filter and maybe shaft seal. Mower has 215 hours on the clock. Compression check readings are 75 to 80 psi. What's going on?
@@MowerMike Thanks Mike. Are there any recalls on this engine? Why would rings go bad with only 200 hrs? I take care of it oil & air filters, oil change twice a mowing season.
Found the trouble , last person did not do the job correctly there was a metal chip between the cylinder head and the intake gasket ( the guy probably used a screw driver and chipped the head )
I would not use W40 or any other penetrating oil on rubber parts (unless they are silicone rubber). It will cause they to degrade prematurely. A better choice, on petro-based rubber, is silicone oil.
@@MowerMike Yeah, my step mother used to work for them and I've been in the military too, but that doesn't have anything to do with the chemistry behind it. WD40 also makes a silicone oil, BTW.
@@akonitony2 - WD40 may _now_ be a product line, but it originated as a single product. It's like 'Loc-tite', which is _one_ product. Now the company uses it as a portmanteau for all of their 'tite-n' thread locker compounds. So, when you say 'wd40 silicone oil', anyone with a memory will get whiplash looking at you funny.
@@tbelding Yes, Captain Obvious, Crescent Wrench, Vice Grips, and a plethora of others are the same way. Not sure what your point is tho? WD40 is the 40th try at a Government Issued Water Displacement formula. It's very close to kerosene. I've had years of chemistry courses at the U of F, which is why I made my comment. Care to address the actual topic? Petro-based oils will degrade and dissolve petro-based rubber in a reaction that is known as like-dissolves-like we learned in the very first semester of General Chemistry I. WD40 is a petro-based oil in it's original formula, but like I said, they now make a version that is silicone oil, which one should not use on silicone rubber hoses, but should use on petro-based rubber just fine.
Do you know if the fuel pump has a check valve in it? My L118 starts hard (extended cranking) when it sits for about a week. I did adjust the valves on it. If I spray starter fluid in, it starts right up. After the initial start, when I shut it off, it starts right back up. It almost seems like the carburetor bowl is empty after it sits for a few days or a week or so. I appreciate any help!
I converted one of my lawn tractors to the vacuum port in the dipstick tube as it seems to pulse better. I'm just tired of ethanol and it went up 5 percent while the price shot up. Makes zero sense.
@@MowerMike my vtwin has an intermittent pop from the carb and surge or sputter. I can’t completely get it away! Some days it doesn’t do it at all and runs fantastic. I’ve set valves, changed plugs, filters, coils. Tried cleaners boosters, but being intermittent I just can’t pinpoint the issue. I always have fresh gas, the battery is charged. I just am at a loss. This thing has 65hrs on it. I guess the next thing I put will be a new fuel pump, can’t hurt
@@walter2670 It sounds like the plunger on the bottom of the carb is not working right. It is the deal the wire is hooked to on the bottom of the carb that plunger is a backfire preventer. Make sure it has a good connection and you can remove it and check it. When you turn the ignition on the plunger should come down and when it is off it goes up to stop the fuel flow and prevent that pop you hear.

Thank you so much. I love how simply and to the point.
Ah shucks, glad it helped
Thanks for the number of that little hose. I needed that
Sure thing there are a few different ones I put the links in the description.
My L100 has a cracked fuel tank, a bad fuel pump and a few hard fuel lines. Ordered the fuel pump, fuel line. Need to order the tank.

Hey the fuel pump for my mower was bad. I fixed it thank you. :)
Well done, you fixed it not me.
@MowerMike haha. That's right. Thank you for the info though. :)
This looks like same fuel pump I have on my snapper zero turn. It's a 25hp Briggs and Stratton. Hopefully it will work, TKS Boss for the video!
Yep they are mostly the same, there are different styles of hoses though make sure to get the right one.
GREAT video, super clear and great presentation. Fun stuff!

Great video
Glad it helped, get to cuttin
My bolt hole is stripped, how do I get the fuel pump to stay on now?
Just use a bigger screw, it just goes into the plastic.
Hey ? Deer d 170 have to hold my hand over breather hole to get cranked
Just throw a new pump on they are only a few bucks

Your engine is shot and pressure is getting past the pistons. Your compression should be over 120 lbs on that motor.

@@vincentpascale9371 No idea. Maybe try and pull the valve covers and see if a valve is broke or a push arm issue
Do you have a link for that vacuum line?
Look in the video description, I have Amazon links to the ones I used there
My vacuum line was good, but there was no fuel in the lines or pump when I removed it. I have a new pump on order.
Get’r done
My vacuum line is blowing air and air gets stuck in the fuel filter . What could be the cause?
That maybe blow back, sounds like your engine is getting pressurized which means it may have an internal engine issue.
When i choke my LA145 I smell gas and it seems to flood out. Any ideas?
The gas isn’t getting through the carb jet. Need to take it off and clean it or replace it
I have a 24hp briggs on my la 165 is it normal for me to hold it cranking for 8 sec when i dont use it for 2 or 3 days ?
No it should start right up, may have a weak fuel pump. But the important part is that it still starts!
All right thanks ill try to make a debit test on it
Fuel pump is fine and the tube is also fine i got the carb off and will clean it

$6 for a fuel pump!? where!? haha. Cheapest I saw online was $20....$30 at my dealer of course
I have no idea, half the stuff I spew in these videos I just make up as I go. Ohoh my secret is out lol
"What" what' lowball ! No body does' that ! 😜
Haha right
Why didn't you start it for us? Pretty sure it will run but you left me wantin more brutha.....
Haha dang it, sorry for the tease. Won’t let that happen again
my "John Deere" replacement pump was $46!!!
L110
They are all the same pumps
Nothing runs ( as high price) like a deere.
I paid $56 at john Deere dealer
Damn, as long as it works right
Those pumps are more like $25 not $5, or $6, dollars. Always make sure to use OEM.
Weak sauce, I say use the Amazon ones.
Six dollars? Try $37.94 at the local implement.
Try the Amazon link in the video description
$6????? Can you sell me a few????
Haha yep the price has gone up a bit since I made this video. Still a cheap fix
The fuel pumps are about $20-$25,
Not $5-$6.
And even the name brand fuel pumps on
The market today are all junk!
All of these parts are made in China these days just how it is. Most have worked good for me though
One day at band camp I fixed my mower !!!!
Haha congrats my man on the fix and the very witty smartass comment! Well done, had me giggling here.
