Product Description
CUMMINS 3949692 OEM ENGINE OIL PICKUP TUBE (OIL SUCTION CONNECTION) – ISB 5.9L (2003–2007)
The Cummins 3949692 OEM engine oil pickup tube (oil suction connection) is the genuine Cummins part that draws oil from the pan to the pump on 2003–2007 Ram 2500/3500 trucks with the 5.9L ISB. When you are rebuilding the bottom end, resealing the oil pan, or chasing low oil pressure, this OE-geometry pickup tube restores the correct pickup height, pan clearance, and oil flow your 5.9L Cummins needs for long life.
Unlike generic aftermarket tubes that can sit too high in the sump or leak air at the seal, the genuine Cummins 3949692 pickup matches OE bend geometry and mounting points. That means stable oil pressure under towing, racing, and high-mileage daily driving. Cummins also catalogs this number as an oil suction connection used on select EPA13 ISB/QSB applications, so you get a robust design proven in demanding on- and off-highway service.
Key Features & Benefits
- Genuine Cummins 3949692 oil pickup tube – not an aftermarket reproduction.

FAQ
Yes. This is the correct OEM oil pickup / oil suction connection for most 2003–2007 Ram 2500/3500 trucks equipped with the 5.9L ISB common-rail engine. For absolute accuracy, always confirm using your VIN and Cummins ESN, especially on swapped or mixed-year trucks.
DOES THIS PART ALSO FIT 6.7L OR INDUSTRIAL CUMMINS APPLICATIONS?
Cummins catalogs 3949692 as an oil suction connection used primarily on certain EPA13 ISB/QSB engines in addition to the Ram 5.9L ISB coverage. Industrial and equipment applications vary widely, so you should always confirm by ESN and compare the pan and pump configuration before ordering.
DOES THE CUMMINS 3949692 PICKUP TUBE COME WITH THE O-RING OR SEALS?
No. The pickup tube is typically supplied by Cummins without the O-ring or additional sealing hardware. Always install a new OE-quality O-ring or seal when replacing the tube to prevent air ingestion and oil aeration.
DO I HAVE TO DROP THE OIL PAN TO REPLACE THIS PICKUP TUBE?
In nearly all Ram 5.9L ISB applications, you must remove the oil pan to access and replace the pickup tube. This is an excellent opportunity to clean the pan, inspect for metal or sludge, and check bearing and crank condition before reassembly.

This listing is for a 100% genuine Cummins OEM 3949692 oil suction connection. CPP Diesel does not substitute aftermarket components on Cummins genuine parts listings, so you get the exact fit and performance Cummins engineered for your engine.
