This is the genuine Cummins 3942592 fuel drain tube — the OEM-formed steel fuel return line that runs from the tee fitting to the quick-connect return-to-tank on 1998.5–2002 Dodge Ram 5.9L 24V (VP44) trucks. Engineered to meet or exceed factory spec, this direct-fit line requires no cutting or bending. Installation restores proper return-to-tank flow and helps maintain a leak-free, factory-spec fuel system. Includes original-style grommet and nut. Use this tube when replacing damaged or corroded return-to-tank plumbing — or when refreshing the fuel plumbing for a clean, reliable install.

FAQ

WILL THIS FIT MY 1998.5–2002 5.9L 24V CUMMINS RAM? Yes — this tube is designed specifically for VP44-equipped 24-valve trucks ('98.5–'02) and follows factory routing from the tee fitting to the return quick-connect.

IS THIS THE LINE THAT GOES FROM THE TEE FITTING TO THE TANK QUICK-CONNECT? Correct. This is the return-to-tank section; other adjacent sections (and the tee fitting) are available separately.

WHAT OTHER PARTS SHOULD I REPLACE AT THE SAME TIME? Common pairings include tube 3942966, tee fitting 3905353, and VP44 return line 3945707. Consider replacing any aged grommets or clips for a leak-free job.

IS THIS A GENUINE CUMMINS PART AND DOES IT INCLUDE HARDWARE? Yes — this is an OE Cummins tube. It includes the grommet and nut consistent with original hardware, per OE kit/retailer listing.

WILL THIS FIT 2003+ COMMON-RAIL TRUCKS? No — this line targets VP44 ('98.5–'02). Common-rail trucks use different hard lines and connections.
