The Aeromotive FPR has a 1/4npt port for an accessory gauge and we are now offering a fuel pressure gauge which screws directly into this port. Most every tuner likes to be able to see the fuel pressure directly at the FPR and this mechanical gauge is just the right set-up and the price is great as well.
Liquid filled to minimize shock and with a reading of 0-100psi it covers the entire range possible. EFI system pressure compatible.
