Continuation from last post...

Last week when I did test runs, I took a couple turns and had low fuel in cell and the truck bogged shortly after turn but then picked up. So I figured pump was not getting fuel through turn because of low fuel level... But the next day when I took it out, after the pump started making the high pitched squeal, it bogged down anytime I tried to give it some throttle. (I added about 5 gallons so it wasn't low on fuel).

Could air be in the line and not releasing through return? I haven't checked fuel pressure, guess that would be a good start?

In park if I rev the engine it's smooth, no bogging down? I have always kind of had an issue with starts as sometimes I have to give it a little gas... but checked fuel pressure at first start up and it was at 58psi. That was a year and a half ago...
