Cummins Genuine Mechanical Fuel Lift Pump — 1989–1993 Dodge Ram 5.9L Cummins — 4983584

Genuine Cummins mechanical fuel lift pump for the 1989–1993 first-generation Dodge Ram 5.9L Cummins.

The 12-valve Cummins uses a mechanical lift pump driven off the camshaft. They are reliable, which is why a failure tends to be a surprise rather than something you saw coming.

This is the genuine Cummins replacement. It goes in where the factory pump came out and installs using the factory hardware.

On a first-generation truck, keeping the fuel system to the original mechanical arrangement is often exactly what the owner wants.
