Ian-
In my experience, regular teflon plumbers tape dissolves in a very short
while. You might try the yellow tape for natural gas fittings though...I
think it is made to withstand chemicals a little better. I haven't tried it
yet, but when my petcocks start leaking again, I'll probably use it. BTW,
remember that they do not use washers...those were the cause of 99% of my
leakage problem. The threads on the petcock are slightly tapered (like iron
plumbing parts) and will seal real good without too much help. I have no
tape on mine and only get one drop every few days which is wonderful in my
opinion.
Hope this helps!
Cheers!

Hi All,

Well...I must say...I am about sick and tired of always dealing with leaky
petcocks.

The originals on my 70 Ambo are seeping a bit and I was wondering what
others have done to combat this cantankerous issue. By the way....does
standard plumbing thread tape hold up against gasoline?

On my 69 Ambo I have installed the newer type (from Convert etc...)
petcocks with an adapter available from Moto International. Works perfectly
except the petcock comes down too far on the left side and gets in the way
of the throttle cable coming out from the top of the carb. Right side is ok
though.

I was thinking of running an adapter 90degrees and bringing the petcock
further back. The pitch on these threads are 12x 1.0 right?

Any thoughts would be appreciated.

Regards....Ian
