pet peeve / pet cock

[GS450inSF]

My stupid petcock is dripping... I bought a rebuild kit, cleaned all the parts and put it all back together and it still dripping. Its the kind of petcock that only has a on/res option (no off position). From what I hear is that gas should stay in the tank and move only if the engine is turned over or running. I am at a loss. I took it apart a few times and can't figure out whats not sealing. Any ideas? Did I miss something...

The rebuild kit diaphragm might be just slightly a different size than the original or may have incorrectly been seated. Just a thought...

When disassembling the petcock, the last part you pull our/remove is the plunger. On the end of that plunger there is fitted an "O" ring. It is not uncommon for the "O" ring supplied in rebuild kits to be slightly undersize (thickness) and consequently, you can assemble everything correctly and it will still leak just as badly as before. Replace that "O" ring.

I just took the assembly apart, again... Then looked to see if the o-ring was seating & sealing and it's not! I am now on the way to the hardware store to get a bigger o-ring. Thank you everyone for your help and suggestions. This is by far the most helpful website I have ever found!

The O Ring point is a good one - we've notice this problem with some kits. However, often the problem is wear / corrosion on the seat in body of the petcock - in these cases putting new seals and O rings doesn't always solve the problem. Sometimes it is possible to dress this surface and get it smoother - but often the petcocks just cannot be effectively repaired.

o ring, o my...

I went out and found an o ring that was just a shade larger (od). I then stretched out the spring a little and put it all back together for the 80th time and it works! I think the big factor was not so much the o ring but the spring. I think the o ring wasn't sealing because it was not being pushed hard enough by the spring. I could be wrong but I don' care cause it now seals. Thank you to everyone in helping me solve this issue.
