Product Description
The CUMMINS 5269589 OEM OIL GAUGE TUBE (DIPSTICK TUBE) is the genuine B-series dipstick tube used on many 1989–1998 Dodge Ram 5.9L 6BT / 12-valve applications. If your original tube is rusted, cracked, or leaking at the block, this factory Cummins replacement restores accurate oil level readings and a clean, leak-free seal at the crankcase.
Why Choose the Cummins 5269589 Oil Gauge Tube?
- Genuine Cummins part – correct bends, diameter, and end-form for B-series applications.
- Direct-fit replacement for many 5.9L 6BT / 12-valve Ram trucks and B-series equipment.
- Restores accurate oil level readings when paired with the proper OEM dipstick.
- Corrosion-resistant steel tube with OE-style flares to help prevent leaks at the block.
- Backed by Cummins engineering for durability in both on-road and industrial service.
Fitment Details
This tube is used on many B-series applications and is commonly installed on:
- 1989–1998 Dodge Ram 2500 / 3500 with 5.9L 6BT / 12-valve Cummins (verify by ESN and existing tube style).
- Certain 5.9L 4B / 6B B-series engines used in industrial equipment such as CASE and JCB 12V applications (always confirm by engine serial number and Cummins literature).
Cummins also associates this tube with and/or lists it as a replacement for the following part numbers on some B-series platforms: 3279104, 3280885, 3905425.
Always verify fitment by VIN and engine serial number (ESN) and by comparing your existing tube before ordering.

Installation & Usage Notes
- Carefully remove the old tube and clean the block bore before installing 5269589.
- Lightly lubricate the tube-to-block joint (such as Cummins 3279104) to ease installation and help prevent damage.
- After installation, confirm the dipstick seats fully and verify oil level against known-good service data.
- If the truck has a non-stock oil pan or has been converted/swapped, double-check tube and dipstick calibration.

FAQ
WILL THIS TUBE FIT MY 1989–1998 5.9L 12-VALVE RAM?In many cases, yes—Cummins 5269589 is used on B-series 5.9L 6BT engines in the 1989–1998 Dodge Ram era. Because of year-to-year and chassis differences, we strongly recommend verifying by VIN and engine serial number and comparing the shape and end style of your existing tube before ordering.
IS THIS TUBE THE SAME AS CUMMINS 3905799 OR 3905801?
No. Cummins 3905799 and 3905801 are other OEM oil gauge tubes used on specific 12-valve truck applications. Part 5269589 is a B-series tube that crosses to or replaces several Cummins numbers in certain builds and industrial applications. When in doubt, match by ESN and by the original part number stamped on your tube or printed on the Cummins label.
WHAT OTHER CUMMINS PARTS SHOULD I REPLACE WITH THIS TUBE?
Whenever you replace the oil gauge tube, inspect and replace supporting parts as needed: the tube-to-block joint (such as Cummins 3279104), the tube clip ( Cummins 3923016 ), the tube end on later trucks ( Cummins 3905802 ), and the correct OEM dipstick ( 3928740 ’94–’95 or 3923128 ’96–’98 ).
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This is a genuine Cummins OEM oil gauge tube supplied through CPP Diesel. We do not substitute off-brand or “will-fit” parts for this listing, so you get the correct geometry and material spec intended by Cummins.
WHAT IF MY TRUCK HAS A SWAPPED OR MODIFIED ENGINE?
If your Ram has a pan swap, engine swap, or custom conversion, the original dipstick calibration may no longer be accurate. In those cases, we recommend matching the tube and dipstick by engine serial number and confirming oil level using Cummins service procedures rather than relying purely on model year.
