Fuel Pressure Testing

Fuel Pressure Testing
Am testing fuel pressure on my S. Due to easy access of the rubber return fuel line at the FPR I am using this. Would the fuel pressure be a useable number after the FPR on the return line? I am getting a reading of 12psi which is drastically low and would provide reasoning behing my intermittent stalling and hard starting...
I assume this pressure is lower being down stream in the system... However how much lower would this be..

Realising my mistake while thinking about it last night I am now sitting in the office trying to think of an easily accessible fuel supply line prior to the rail. Is there a rubber fuel line that is close?
Anyone have a picture of their bay around that area or a decent diagram?

According to the helms, you need to remove the fuel pulsation damper on the fuel rail (looks like a big knob thingy) and attach the pressure gauge there. fuel pressure should be between 47 and 54 psi.
