'01 Dodge Cummins lift pump failures
Bought this truck new. Had a 54g TransferFlow fuel tank installed. Now has 155K miles. Have replaced the fuel lift pump three times. Dodge claims a redesign installed in the tank instead of on the engine block has cured what Cummins claims is an undersized tank to engine fuel line. My Dodge service center says the tank mounted pump can not be installed in my tank. TransferFlow tech dept sees no reason it can't.
Do any of you have any experience to share here? But for the lift pump concern, I'd prefer to keep our truck. Thanks in advance for any insights.

Place the lift pump between the tank and engine. Our 5.9 had this arrangement when we bought it. It's easy to install there and allows easy access to an inline filter placed before the pump. There are several to chose from and as stated by other posters the TDR and Dodge Cummins Diesel forums can help. You also should consider a fuel pressure gauge to monitor pressures to the injector pump.

An old tried and proven remedy that has been used to cure sluggish and tired lift pumps on a great many Detroit and other diesel systems for decades is to install an inline 12 volt fuel pump between the tank and engine , powered through a relay that is activated when the system is turned on. It does not have to be higher pressure than supplied by a low cost electric in line fuel pump from just about any parts stores . All the ones I have personally installed were for gasoline , and they work just fine for diesel. I have one that's still in use after 30 years .

Our shop truck has had an issue with the lift pump, and Dodge has repositioned it on the frame rail, next to the tank. They say there is a TSB that outlines this procedure. According to Dodge, the original location was at the front edge of the cab, near the engine.
