This is the adapter I bought with the gauge. If I'm understanding you correctly, This one doesn't have a valve or a place to bleed air.
Fuel pressure?

Thanks for the response. ... I'm not running tuned. Truck is completely stock. My regulater did not use the black bushing either. i do have a good snap on mechanical gauge so I will plumb that in today and compare readings.

How did you install your Fuel Pressure Sending unit?
If there is any air in the line/sending unit it might read inaccurately.
I used this and my sending unit is down low by the pass-through wires.
I get 65-70 at idle and 60-ish at WOT..

Common belief, but it won't change the pressure. In less then a second it will just compress to a smaller volume in response to the pressure and act as a dampening accumulator diminishing any pulsations of the fluid.

Yes, we all have electrical fuel pressure sending units. The adapter just lets us keep the sender away from the vibration that can kill them quickly, and the adapter has a valve to bleed air, or mount it low so air just rises on its own.

Another check you can do is disconnect the lower line on the rear of the hfcm and check for anything over 6in of restriction on the feed line from the tank. Do this with a simple brake bleeder. It is a quick check I do before replacing the high dollar hfcm. Healthy systems will pump fuel very easily without any restriction (with the bleeder).
