    plumb a foot pump into the fpr pipe and press if it holds on the foot pump gauge its ok. you can also do this with the aei unit aswell but only do it to 20 psi no more or you my damage the diaphram.

    The STD FPR should maintain fuel pressure 4 psi above boost pressure so you always get a positive supply of fuel.
