Cummins 4BT 3.9 and 6BT 5.9 Lift Pumps

Show/Hide Details
Cummins 4BT/6BT Lift Pump

Maximize power in Cummins B-Series engines with lift pumps from Diesel Parts Direct. Significant drops in fuel pressure from malfunctioning lift pumps can create problems in the Cummins 3.9 and 5.9l engines. Failure to replace the lift pump prevents Cummins 4BT and 6BT fuel injection pumps from functioning efficiently. Before major repairs are needed, upgrade with a 3.9 or 5.9 Cummins lift pump from Diesel Parts Direct.

Loss of power and high fuel consumption indicate the lift and fuel injection pumps need replacing. You’ll be glad to know various pumps are held in stock, come with a 12-month warranty and ready to ship the same day to minimize downtime.

Make sure that fuel is flowing to your Cummins 5.9 with lift pumps from Diesel Parts Direct.
