I installed an auto meter fuel pressure gauge(electric) into my camaro and the gauge I know wasn't reading correctly (or so I thought). The gauge was only reading 27 psi at idle and 35 or so at full throttle. I have an adjustable fuel reg which can only go down to 35 psi. I am using eurl fittings and the set up is perfect. So, I sent the gauge back in hopes the I would get a good one. Put the new one on and it read wrong AGAIN!! I then decided to test a theory. Hook up a mechanical gauge and everything read normal. THe interesting part... I put the accel gauge onto the eurl fittings and the pressure read low. So, its the fitting, at least that is what I guess. Anyone have a problem with this??? For a S/D TPI.... thanks!!!
