So I installed a fuel pressure sensor on my Perrin fuel rail and its leaking at the threads. What kind of sealer do you use on this. I'm not sure what wont break down over time from the gas.
Thx for the help guys.

 

Beuler?

 

Bump

 

Nobody has an answer to this problem? Will teflon tape work or will it break down also?

You should not use teflon tape. I'd use the paste thread sealer made by Loctite or a similar product.

 

I have thread sealant, but its used in plumbing applications. It's a heavy grey sealant but it didn't hold against the gas. Is there a special thread sealant that holds up to the degrading properties of gas?

 

Yes. Look at Permatex and Loctite product lines
