Product Description
CUMMINS 3923083 OEM P7100 INJECTION PUMP OIL FEED LINE – RAM 5.9L 12-VALVE (1994–1998) | CPP DIESEL
The CUMMINS 3923083 is the OEM-quality braided injection pump oil supply hose designed specifically for the P7100 pump on 1994–1998 5.9L 12-valve Dodge Ram 2500/3500 trucks. This flexible hose restores correct, pressurized engine oil flow to the P-pump — essential for lubrication, cooling, and long-term pump reliability. Built to Cummins’ exacting standards, it ensures a proper drop-in fit, durable service life, and improved reliability over worn or leaking original lines.
Install the 3923083 and you restore factory oil feed integrity and prevent pump wear or failure due to inadequate oil supply. For best results, inspect associated fittings and the oil tee — often replaced together (see “Fitment & Cross-Reference”).
