Fuel pressure gauge reads 7psi?
For some reason on Jason sadler's car, the fuel pressure gauge currently reads 7 psi at idle and 10 psi while moving. What could be causing this? Obviously the car is seeing more than 7psi of fuel pressure if it runs, but what would cause the gauge to read this?
The fuel setup is a stock FPR with a Cartech FMU, and he has a full sweep Autometer fuel pressure gauge. Everything was brand new. Currently the fuel pressure gauge is tapped into the line exiting the fuel rail, right before the FMU. Should we put the sender before the fuel rail?
On my car, we put the sender right after the fuel filter, and it always read accurately. But someone told us it would be fine to tap it right after the rail, so he did it.

It should be on the exit line after the Cartech going back to the tank. Most people recommend this spot instead of the supply line.
I told Jason when he called me to put it on the fuel return right before it hits the tank, basically being after the cartech.
