Thanks for the quick response. The tank is almost full, about 50 miles since fill up.
I'll do a pressure test tomorrow to verify if the pump is the problem.
Is a Delphi pump good quality? I see that Auto Zone sells the pump locally only for $144 with lifetime warranty.
FCP and Pelican sell Delphi pump and sending unit assemblies, so I'm thinking the Delphi pump must be an ok alternative. But FCP and Pelican don't sell just the pump by itself.
Pelican does sell URO brand pump and sending unit assembly for $125, with a 24 month warranty. Is the URO assembly good quality? I've had good luck with Pelican, but not sure about URO quality.
