fuel pressure gauge
 

where can I get the fitting for testing fuel pressure

A hydraulic shop. The fitting is 1/8 NPT x M12 x 1.5

I got mine from Diesel Manor, along with the fuel pressure gauge.

By the Way........ what's the correct fuel pressure I should be seeing with the blue spring upgrade ?

My gauge sits very steady on 65psi............. is this correct ?

TIA.............

If you want to order on online Glowshift sells the adapter only, but as posted above any tubing or hose shop should be able to hook you up

That is a good psi,, over 50 but under 70

ihandy....check out ITP (think they're merged with MKM Customs/Sinister)...they have a nice line with a schrader valve.

GSlahor....I read a steady 65psi...sometime it sits at 67.

I took the old plug left over from the blue spring upgrade drilled out the center then brazed on an air fitting so I could attach a hose with a guage to check the pressure worked great
