Going thru this myself on my 98 RK. But oddly no leak. Went to drain my tank and had to constantly pump on the mighty vac to keep enough pressure on the diaphragm to keep it open. Once off the hose to the VOES and carb had fuel in it. Think I finally solved my lean issue with fat jetting and my occasional dexel pop. Thanks for the video.
I'm having same problem with my 2001 fatboy wasn't sure what the vacuum line was for thanks for the info I hope I can find the peacock I hate dealing with the Harley shop always a pain in the a## great info
I’m 66 years old and been riding for 50 years. When I started riding, it was on Triumphs and I got into the habit of turning off my bike in the following way, every time; Key off, petcock off, stand down. I had seen what can happen to a bike if you leave the taap on and the fuel drains through into the engine, past the pistons and rings, and into the sump. NOT PRETTY! One or two examples of the kind of catastrophic damage thata can occur was all it took for us all to keep a sharp eye out to ensure that none of our buddies forgot to do this and of course, they did the same for me. It became so second nature, that I do it without thinking about it, but I STILL doublecheck that it’s off, after I actually get off the bike. All that said, what I DON’T like about these diaphragm petcocks is that they encourage laziness and that’s never a good thing with motorcycles. When I bought my 97 Sportster back in 2007, I didn’t think too much of it, but after the diaphragm started to act-up, I replaced the petcock with a Pingel one, which is brilliant. I wouldn’t go back to the factory setup for any reason.
2000 harley flxts springer, Installed a new petcock from amazon. Bike off full of gas found a puddle of gas tue next day after filling it up non ethenol only It leaks tightened up the nut leaks more. I am confused Is it customary to add teflon tape to the fitting?
Best explanation I've seen yet, only question, can a replace a vacuum type valve with an older, original style valve, plug the vacuum line, on my 1999 Sportster? Thanks, Dave
@@WrenchesCorner thanks for your reply, I'm old school, I'm used to checking the valve anyway. It doesn't seem like much of a safety feature when it dribbles gas on your engine. I just bought a old 1999 sportster, the newest Harley I've ever owned, already outdated! Dave
hello dear I have 1996 heritage evo storage for 7 month without starting the fuel tank have gas from 7 month I try to started but not start did you think that because the fuel is too old ???
While riding about 60 mph the other day, my bike lost power and after i pulled over noticed that the fuel line detached from the bottom of the petcock. The fuel valve outlet on my Sporty detached from the petcock itself and is being held in the fuel line. Can that outlet be pushed back into the valve someway then reassemble the fuel line, or do I need to replace the whole valve?
I would get a new fuel valve. The brass fitting could be pushed back in or tapped back in, but I would get a new valve so that it's not as likely to happen again. Think about a valve that points to the left or right so it's not always pulling down on it. Good luck, and thanks for watching.
That's a good question. The advantage of the vacuum fuel valve is not having to remember to turn your fuel off every time you turn the bike off. You can use a regular fuel valve without a vacuum actuator, but remember to cap off the vacuum line that was going to your original one.
Any idea where to get an after market vacuum petcock for a 2005? I saw some on amazon but they are specified 95-01 , although they look exactly the same as mine fuel outlet to the left just like the one in the video, is the fitting the same on these bikes?, if not , can I just buy this aftermarket and use the diaphragm and build my old one with it.? thanks
I would get a new Harley fuel body. The aftermarket ones aren't vacuum operated. The one for the earlier years should work with your fuel tank fitting. The diaphragms are going to be different and aren't interchangeable. Good luck with your project!

I'm glad you were able to figure it out! Fuel in the vacuum line is not good. Thanks for watching!
AWESOME INFO!!!
Thanks! I hope it helped out. Thanks for watching!

They do promote laziness. I agree, but with a little maintenance, they do work well. Thanks for watching!

Is it customary to add teflon tape to the fitting?
You shouldn't need teflon on the threads. You have to have a screen in there. It has a plastic ring that seals it.
You broke the thread's unfortunately.. try teflon

Yes you can remove the fuel valve and replace it. But don't ever forget to turn your fuel off !

@@WrenchesCorneri have replaced the petcock with an old standard one.. Never two years now ever closed the line.. Never had any issues 😊
whats the best way to cap off the vacuum line
I've had bad luck with vacuum caps disintegrating from dry rot. I like to use a short length of hose and screw a bolt in it.
hello dear
I have 1996 heritage evo storage for 7 month without starting the fuel tank have gas from 7 month I try to started but not start did you think that because the fuel is too old ???
also before I stopped the bike I was clean carburetor after that I storage
That is likely, fuel doesn't store well. You should check out my video on motorcycle storage. ruclips.net/video/638rcgxj4rs/видео.html
Would a leaking diagram cause a vacuum leak, affecting performance?,...🤔
Absolutely! The fuel wouldn't flow properly and there would be a vacuum leak.
I got the value out but the screen is stuck in tank any idea what I should do????
I have had to use a pick before to pull it out. It wouldn't be the best solution, but you could push it into the tank and shake it out of there
Ok thanks
Any idea what the part number is ? Only thing. I found was Japan

You're welcome! Thanks for watching!
45 Bucks from WHERE? Order the "right one" from WHERE? What was your parts source? That would help a lot.
Harley Davidson only. I don't buy aftermarket fuel valves. They are all made cheaply. Just go to your dealer. Thanks for watching.

Do I have to use a petcock with a vacuum, or can I you use one without a vacuum. on a sportster.
That's a good question. The advantage of the vacuum fuel valve is not having to remember to turn your fuel off every time you turn the bike off. You can use a regular fuel valve without a vacuum actuator, but remember to cap off the vacuum line that was going to your original one.
@@WrenchesCorner Thanks, I think I will go with the vacuum one. There are a lot of after market petcocks for $ 20 with on vacuum.
