is ptfe tape petrol resistant? got a problem on my pressure reg, its got a take off for a gauge but the blanking bolt that comes with it wont seal. its only brass into ally and i dont want to over tighten it!

Any suggestions folks?

 

soak the tape in some petrol,and see what happens

 

cheers wil give that a try

 

try a fibre washer.

 

tried that. no shoulder on the plug for the fibre washer to seal to.

 

Should be fine

i used it on my fuel pressure guage and it worked fine.

 

How about one of these, if they do them small enough ?



It's called a sealing washer, or dowty washer Got them from a company called Pirtek, I think they've got branches nationwide.
