Product Description
Cummins 3928455 — Genuine Engine Oil Pickup Tube (Oil Suction Connection)
MPN: 3928455 | Also Known As: oil suction connection, oil sump pickup tube, oil pump pickup
The genuine Cummins 3928455 oil pickup tube restores reliable oil supply on 1994–2002 Ram 2500/3500 5.9L engines (12-valve & 24-valve).
