fuel pressure question

[dsmoverboosted]

Is the pressure at the pump suppose to be the same as at the rail? Would 70 psi at the pump be normal on a stock 1g turbo fpr at idle with or without the vac line in?

No. Measure from the banjo fitting on the top of the fuel filter, mounted on the firewall.
Stock pressure for a 1G is 36psi no vacuum to the FPR, or ~27psi with vacuum.

Not to be a douche, but its 37 psi with the line off. It should drop around 10 psi when the line is connected.
