If you're experiencing repeated failures of the fuel lift pump in your 2002 Dodge Ram with the Cummins 5.9L engine, there are a few considerations to keep in mind.
Heat and location: Excessive heat from the engine compartment can potentially impact the lifespan of the fuel lift pump. If the current location of the pump exposes it to extreme temperatures, relocating it to a cooler area could help alleviate the issue. Installing a low-volume fuel pump on the frame rail between the tank and engine could be a feasible solution if it provides better heat dissipation for the pump.
Distance and strain: The distance between the fuel tank and the engine can indeed place strain on the fuel lift pump. If the current setup is causing undue strain on the pump and leading to premature failures, you may want to consider alternative fuel delivery options.
In-tank fuel pump: Installing an in-tank fuel pump is generally considered a more reliable solution. In-tank pumps are designed to be submerged in fuel, which helps keep them cooler and extends their lifespan. They also provide better fuel flow and pressure, which can be beneficial for performance.
Aftermarket fuel system: Another option is to install an aftermarket fuel system, such as a fuel sump kit or a fuel air separation system. These systems can improve fuel delivery to the engine and help alleviate strain on the lift pump.
