I have the BSA style with cork. I have replaced cork but still leak. What is the best complete replacement for them?

Thanks for the help.

There is someone on eBay that does a replacement with 2 o rings. I have not used them but worth a look.

Also Britgaskets.com did one but can't see it now on their website, I have used Steve's gaskets and they are good.

BSP ball valves work very well, don't leak and don't vibrate themselves shut when giving it the berries

Anything not made for bikes works better and costs less than anything that is!

Do these ball valves have correct threads?

Red, I've found the 1/4-turn, all metal taps I got from British Cycle Supply to be very reliable. There are cheap ones and better ones; I think the better ones are made in England. If you talk to the guy at BCS, he'll know. They only come in the 1/2" diam. (I'm talking about the outer diameter; I know they're not sized that way), but they have solid brass adapters to fit the larger BSA tap holes. If you go this route, also ask for the "squish washers" (rubber sandwiched between copper) that go between the tap nut and the adapter. The adapters come with fiber washers to mate to the tank.

I am currently using the eBay orings in my taps. They aren't the easiest to pull out or push in now but so far no leaks. Granted I have very little fuel in the tank just for test starts but it's had some fuel in there for a few weeks with no leaks.

I'm with Mark Z.

Had one on my bike for over ten years without any issues. Easy to operate with gloves. Look okay.

I had the two o-ring type at one point. The inner o-ring always got nicked, defeating the purpose of a fuel cut off. I stopped using them after I walked out to my shed, smelled gas and realized that my crankcase had filled with fuel. BUT it did keep the fuel from leaking out of the end of the petcock all over the crankcase.

The o-ring push-pull do seem to give up and quit after a very short time.

Most which fail get damaged before installation,
when the buyer starts operating them dry.

I boil my old plungers with corks in some water with oil and install them using liquid soap.
Am good for a season.

Mark Z. I might go that way if it starts leaking again.

Adam M. I will have to try that. I soak mine (not boil) and use petroleum jelly to lube.

Thanks for all the suggestions.
