FAQ
WILL THIS FIT MY 1989–1998 5.9L 12-VALVE CUMMINS RAM?
Yes. 5269589 is intended for pre-common-rail 5.9L B-Series (12V) applications used in 1989–1998 Ram 2500/3500. Verify by VIN/ESN.
DOES THIS TUBE FIT 1998.5–2002 24V OR 2003–2007 5.9L?
No. Those engines use different tube/dipstick combinations. Order the correct tube for VP44 (’98.5–’02) or common-rail (’03–’07) platforms.
WHAT OTHER PARTS SHOULD I REPLACE WITH THE TUBE?
The tube-to-block joint/clip (often P/N 3279104) and a known-good dipstick matched to your year/engine. Inspect brackets and seals.
IS THIS A GENUINE CUMMINS PART?
Yes—OE Cummins part 5269589 for proper fit and durability.
HOW DO I VERIFY FITMENT?
Match by VIN/ESN and engine family (5.9L 12V). Industrial B-Series variants should also be verified by ESN.
