Dodge Diesel/Cummins Mechanic Advice Needed

Dumb question, I assume the fuel filter's been changed thru all of this? There is nothing wrong with the stock Carter lift pump; the problem is the LOCATION. It's too far away from the tank, and eventually will burn up trying to SUCK fuel rather than push it. That's why on a drag car you mount the electric fuel pump as close to the fuel tank as possible. Electric pumps work best at pushing fuel rather than trying to suck fuel, and the distance away from the tank on a stock Dodge is more than the distance from the lift pump to the injector pump. They make kits to move the lift pump back by the tank, or even IN the tank.
