I disconnected the fuel line from the fuel rail and then plugged it (the line) with my thumb so that there was a very definite very tight seal around it. I know my thumb wasn't leaking. Then I had a friend turn the key to prime the system. Again, the pressure went up to about 40-50PSI when it primed, but dropped back down to 0 within 2 seconds.

That being said, tomorrow I need to make sure that the gauge isn't somehow leaking.

I mean... it's starting to look more and more like the fuel pump, or the check valve that's integrated into it, because if it were actually a leak like this would cause fuel to actually come out from SOMEWHERE in the system, and I'd smell or see it.

Any opinions?

Thanks for all the help so far!!
