UPDATE:


Had someone clamp down on the return line while I primed the pump......fuel pressure gauge read about 70 psi or so for about 2 seconds.


This tells me:

1) The fuel pressure gauge DOES work
2) The fuel pump is capable of still producing a fuel pressure of 70 psi or so.


The next test to do is to prime the pump while hooking the vacuum line up to a 20 psi boost source (probably will just used a small air compressor).



This should prove whether or not the FPR is actually working correctly.
