460 fuel problem

Hello, I got a 96 f250 7.5l that ive experience loss of power when accerlating, this only happens on the rear tank. Pulled the bed and replaced both pumps and noticed the rear been changed before. Still acts the same way and I followed the fuel line to see if maybe its kinked but im not seeing anything. To my understanding these gas engines doesn't have some selector mounted on the frame so im kind of a at a lost here since the front drives perfect. Any suggestions would be appreciated (fuel filter also replaced)

I just went through this with my 97 460, everyone recommends the Delphi fuel fuel pumps and I believe they are one of the better options, however, I got three Delhi fuel delivery modules in a row that were bad out of the box. Two of them the pump was low pressure and had same symptoms, the third had a faulty shuttle valve. The fourth worked as it should. I would definitely check your new fuel pump pressure under load with the pressure gauge taped to the windshield. Don't assume the pump is good because it is new. New parts are so bad anymore that it's a total crap shoot if they are good or not out of the box.
