ok so i had an aeromotive fpr with external gauge that went bad and insted of rebuilding it i bought a new fuelab 51502-5 fpr with install kit and gauge. all was going well intill i got to adjusting it. it will not go below 50 psi, the adjustment screw has plenty of room for adjustment. i've tried with the vacuum line off, still will not go below 50 psi. the reason for replaceing the aeromotive fpr was because it was reading at 60psi and it was set for 38 psi. after trying to adjust up or down with no change in idle i figured it was bad. i hadn't changed anything before it went bad, i was just check the oil level when i noticed that it was reading at 60 psi.
so now that the new one is doing close to the samething, any ideas why i can't get it to 38 psi?
have- walbro 255 fp, 450 injectors, 2gen fuel rail and intake manifold, 6-bolt block and head. emissions delete, a/c delete, 2gen ecu
don't have yet but soon- wideband O2, logger, larger injectors, eprom ecu

i could hear the air gurgling in the tank from the compressed air. i took the line off right at the fpr, there was very little resistance at only 60psi from the compressor, probably just the fuel that was in the line.
