Someone had a gazillion of these petcocks made in China or somewhere, and the Chinese supplier really screwed up. Some leak through the valve, some leak out the flippers, and some won't "pass gas". But vendors keep selling them even though they are junk.

These old-style petcocks are hard to find used, and even harder to find in working condition. One problem is ethanol gas - they didn't have that in the 1950s and 1960s, and the rubber they used for the seals wasn't designed for alcohol.

Here's an idea:

There's a million Harley petcocks on eBay, but not the ones we're looking for. On eBay, click the Advanced Search - up in the right hand corner of the screen. Type in Harley petcock, scroll down and click "used". This will screen out most of the garbage.

Maybe you can find a used one that way. It's a crap shoot, unless you find an honest seller that will test it, and guarantee that it works and doesn't leak.

This one comes up - - but it's not the one you want - you want the one with the threaded lower connection.

Years ago, someone on here used to convert the hose-style to the threaded style. Are you still around? I'm thinking that the thread is a standard SAE flare fitting - but I'm not sure about that !!!

The guy would remove the lower lip from the hose-style, modify a flare fitting by drilling it out to a press fit. Then press it on the de-lipped hose style. Maybe red Locktite too.

Harley transitioned from the threaded to the hose-style during the 1950s. The hose style was used until the late 1960s or 1970s - when they changed the configuration of the petcock. So the hose-style are easier to find.

Not a great solution, but maybe workable.

I purchased the petcock fuel valve from J&P Cycles. It is
possible that another one from their inventory may work
just fine. However, this one leaked so badly I prefer to
just get my money back rather than ask for a replacement.
