surging and dies when around 1/4 tank of gas?

[chargedc5]

Need some help..truck runs great until i get around 1/4 tank of gas! took it to the dealer which replaced the fuel pump,(28psi), #1 & #2 injectors, and filters Ran fine for a couple miles and started back up again, (tank was around 1/4 tank).

Truck will start surging with little power and if i don't keep my foot on brake and gas it will die.

Any ideas

What kind of fuel pressure do you have now at idle and at WOT did they install a new fuel reg. spring so does it run OK on the full side.

He said fuel pressure was good, i'm not sure if he installed a new regulator?

sounds like maybe a problem with the pickup in the tank or maybe your sending unit is off and you are actually lower than 1/4 tank? How much fuel does it take to get from 1/4 tank to full?

I will check at next fill up but i believe when i filled with around 18-20 gallons Sunday, right when it started acting funny

Is that normal to start out of know where? Is it difficult to do?

I have read a few threads on here about the fuel pickup cracking and causing this issue.
