Fuel Pressure Drop with inline regulator...

At idle I'm holding 60lbs of pressure... driving at a constant speed its fine.. if I give it a little gas it drops off to 40-50 depending how much I give..

I'm running walbro pump, braided line to front, fast fuel rails, magnafuel pressure regulator with boost ref that I am not using..

So far I have

1. replaced pump.. then swapped entire bucked with a friends.. nothing
2. cleaned filter..
3. checked for leaks..

Regulator -

I doubt the diaphragm has a leak but I could buy a new one to check..

Is there a way to just open it up fully to test it?

any opinions appreciated at this point..

OH... Voltage and ground to pump... That's my next thing but I do have the aftermarket racetronix wiring kit.

I see in your sig it says turbo. If you do have a turbo, and boost ref'd regulator, why not hook it up?

Need more info on fuel line size, how its routed, and is there a return. Sounds like the only variable you havent checked.
