I hooked up my Aeromotive FPR. No matter what I do the gauge won't read past 20 psi. I took the plug out, backed out the vacuum nipple to see if that was blocking it. The spring moves fine. How are you guys routing your fuel lines and any suggestions to why this gauge is only reading 20psi?

Aeromotive 340. 100% sure it's hooked up correctly. Had a walbro 255 in it that was already hard wired.

We'll of your sure you have it hooked up right then either the gauge you have is bad or something is loose on your connections that's why your getting less pressure
