Got a Case/IH dealer close? Take the Cummins number, change the first 3 to a J, and it will be even cheaper than Cummins. I bought everything but the pump at a Case dealer for $42.
Hate to disagree with some of you but the correct Cummins part number for a 1st gen lift pump is 3970880 and the gasket is 3939258. Shadrach
