Default Interesting issue.....Fuel pressure

Hey Gentlemen,

What would cause me to have no fuel pressure at the Fuel Pressure regulator, but good fuel pressure at the rails?

My setup is dual in tank pumps, each running to the back of the rails, then from the top of the rails to the FPR (2 lines) and then finally a return line. The intank setup is the RSI dual pump and all lines are -6an.

Just curious what you might see off the top of your heads.

Could you have a faulty FPR stuck open allowing the fuel pressure to bypass the valve? I have the same set-up but my FPR is located before the rails.
