Product Description
Keep your 5.9L Cummins properly lubricated with the CUMMINS 3928455 OEM ENGINE OIL PICKUP TUBE. This genuine oil suction connection feeds oil from the pan to the pump on 1994–2002 5.9L 12V and 24V engines. If your pickup tube is cracked, damaged, or loose, you risk aerated oil, low oil pressure, bearing damage, and catastrophic engine failure. Installing a genuine Cummins 3928455 pickup tube ensures the correct length, correct sealing, and the precise OE flow path your engine needs.
Many failures on high-mileage 12-valve and early 24-valve trucks come from leaking O-rings, cracked tubes, or improperly seated aftermarket parts. This factory Cummins oil suction tube restores confidence with OEM-engineered geometry, proper oil pump alignment, and long-life steel construction. Perfect for pan reseals, cam swaps, in-frame rebuilds, or oil pressure troubleshooting.

FAQ
WILL THIS CUMMINS 3928455 OIL PICKUP TUBE FIT MY 12V OR 24V 5.9L CUMMINS?
Yes. This is the correct OEM oil suction tube for all 1994–2002 5.9L Cummins engines, including both 12-valve and 24-valve ISB variants. Always verify using your engine serial number for best accuracy.
WHAT SYMPTOMS INDICATE A FAILING OIL PICKUP TUBE?
A cracked, loose, or clogged pickup tube can cause low oil pressure, bearing wear, lifter noise, turbo failure, or intermittent pressure loss during braking or acceleration. These issues can quickly lead to catastrophic engine damage.
SHOULD I REPLACE THE O-RING WHEN INSTALLING A NEW PICKUP TUBE?
Yes. Always replace the O-ring to ensure proper sealing and prevent air from entering the lubrication system. Oil aeration is dangerous and can mimic low pressure conditions.
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This is a 100% genuine Cummins OEM part. CPP Diesel does not substitute aftermarket components on OEM Cummins listings.
WHAT OTHER PARTS SHOULD BE REPLACED DURING A BOTTOM-END REFRESH?
Many owners replace related components such as the front crankshaft seal, turbo drain expansion plug, and front crank seal service kit while servicing their oil system.
