Not that it fixed the problem but atleast i realize i need to vent my tank.
This could have something to do with the air never getting out of the system.
I will hook up an gas pressure gauge tomorrow to see what its running at.

Even if you do replace your fuel pump, make sure to still get a vented cap. Since most of us have no evap setup, I'm assuming we still need a vent/bleed point for the gasses. Plenty of cars have vented caps, hopefully you can find something that fits.
