Well I installed my fp gauge, now I have a leak. Used a brass needle valve, and one other brass fitting. All the other stuff are race fittings from a local performance shop. I couldn't get a straight answer on thread lock, so I didn't use any. Should I have? Is there really a need for the needle valve? Any help would be great.

 

Pipe threads need to have dope on them, to prevent leaks. A valve is a good idea, in case of a leak anywhere, going to the gauge.

 

Where is the leak?

Between which part and which part, back of guage? or out of the needle valve itself?

The brass fitting tapping off a fitting with a fp tap that is conected to the needle valve. I'm headed out first thing in the mornin to get some thread sealer.

 

I use Loctite hardening sealer...no leaks.
