FAQ
WILL THIS CUMMINS 4983584 LIFT PUMP FIT MY 1989–1993 5.9L CUMMINS?
Yes. This is the correct OEM mechanical lift pump for all 1989–1993 5.9L 12-valve Cummins engines using the VE injection pump. It will not fit P-pump (1994–1998) trucks.
WHAT SYMPTOMS INDICATE MY FIRST-GEN LIFT PUMP IS FAILING?
Common symptoms include hard starting, surging at idle, low power, fuel starvation, and excessive cranking. A weak mechanical lift pump can also accelerate VE pump wear.
IS THIS A GENUINE CUMMINS PUMP OR AFTERMARKET?
This is a genuine Cummins 4983584 mechanical lift pump. We do not substitute aftermarket pumps for this listing.
SHOULD I PRIME THIS LIFT PUMP BEFORE STARTING?
Yes. Use the manual priming lever until resistance increases. This helps fill the VE pump and drastically reduces cranking time.
