Anyone have one?..Bought one today to check my fuel pressure...It leaks where the threads of the hose goes into the gauge...Does it need a washer for the fitting or do I just keep tightening it till it stops leaking..?...Thanks...

 

if the threads on the guage are pipe thread, then yes you do need to put thread tape or sealer on them and snug them up.

 

Thank you, that did the trick......Good news...fuel pump mantaining correct pressure while running...Bad news...pressure quickly drops after shutdown...Will be doing leak-down test tommorow...
