Obs 7.3 fuel system leak test question

[F350stroker]

I put together a efuel setup in the valley and replaced the factory seals on the feed lines. Before I throw the turbo and up pipes back on I wanted to pressure test the system up and make sure it has no leaks. Basically just the stuff I changed in the valley, my question is if I hook into the feed line (top line on the frame ?) with air and a pressure regulator should I be able to pressure the system up to when the fpr (tightwad mod) releases and then check for leaks that way? Will the air push through everything and pressure up to the fpr?

I would think so.
