Petcock fix with JB Weld

[Larzfromarz]

Yep, see my new thread and how mine is fixed (at least for now). Just did this today. Can you say "Swiss Cheese?

It's a hard call to advise what to do. I am trying to save a fuel bowl by an application of a heavy coat on the inside of the bowl, polishing the outside and send it off to be chrome plated.

I guess that I would take the epoxy route as a last resort to seal the petcock to the tank. IMO

If it is the bowl that's the issue, I don't see why the inside couldn't be coated with tank Sealant, I'd avoid the prep part of the kit because that stuff will eat aluminum. The gasket leaking issues are a whole other story. I avoided that whole deal and just fit an adapter plate with standard N. P.T. threads, bought a standard Harley petcock. Polished the original one I had, and gave it to Smithers. I like the form of the original, but really dislike the function.

I've used that red epoxy that is cured with heat with success on my fuel tank. It's been over 2 years now and no leaks at all. I would use that to mate the petcock to the tank, especially if the tank is not flat, a gasket will not seat it properly. I think JB weld hold for a while but not too long.

I used a heat gun to cure the red epoxy. No flame of course.....

This is definitely the way to go, and I'd just like to add that you can get these petcocks with a side outlet which I highly recommend as the one that comes straight down puts the fuel line very close to the engine...
