Slow petcock leak?

98 vt1100c
Garage has been smelling of gas lately; I looked a little here and there, and this morning found a drip of gas hanging from the bottom of the petcock and the attached fuel line was wet. Didn't look like the petcock was wet above the bottom. Anyone ever heard of a petcock leaking? Is replacement the only fix? Thanks for your thoughts on this, Jon

How ever the petcock is attached to the tank, I'd be checking to be sure that's secure first.......and replacing the hose too. Fuel can sometimes "migrate" to a point slightly higher than the actual leak.

they can leak if the rubber inside gets riped or as such. you may be able to buy an internal parts replacement kit, depending on what one you have.

Looks like there a O ring that seals the petcock to the tank but the petcock is showen as a unit, BUT I think there's a O ring behind the arm that can be replaced

If you're looking at replacing it I would just replace it with a Pingel fuel valve. They are rebuildable.

Well, that's a fine looking fuel valve; just $10 more than OEM. Sure would rather just replace a couple of o-rings. I'll see if I can get it apart to replace o-rings and if I can't I'll replace. This girl is reaching the age where I'm afraid she's going to nickel and dime me; who would have thought a petcock could could go bad? Think it could be a result of using Seafoam periodically through the years? Ate away at the rubber or something? Jon

little grit in the seal and it leaks

you could add a manual on off valve after the petcock, would stop the fuel from running

Something about this advice doesn't sound right; the petcock itself seems to be leaking. Fuel isn't running when bike is stopped. Adding on/off valve after the petcock wouldn't do anything would it? Jon

Define nickle and dime LOL

I have seen these old girls last beyond 100,000 miles before anything really major--but it's always little stuff isn't it. I yanked my OEM petcock off and put a Pingel on and it definitely flows fuel much better--and I have had it since 1996. If you are going to keep it a while longer then why not use a Pingel over the OEM? That way when it needs a rebuild, you can get a rebuild, and not have to worry about buying an entire assembly. That is if you plan on keeping it--if you plan on parting ways in the near future then I would try also to replace with minimal investment.

Good luck!

Tell me, did the Pingel bolt right on as if it were made for your tank? How pray tell did you you definitely know fuel flowed much better; fuel has seemed to flow just fine with my original petcock. Jon
