Product Description
CUMMINS 3286499 OEM TURBO OIL DRAIN HOSE – 5.9L CUMMINS (1989–2004)
The genuine CUMMINS 3286499 OEM turbo oil drain hose is the correct factory replacement for the return-side turbo lubrication circuit on 1989–2004 5.9L Cummins engines. This hose connects the rigid turbo drain tube to the crankcase drain port, allowing hot oil to flow freely back into the engine. A cracked, hardened, or leaking drain hose can cause oil consumption, driveway drips, burned oil smells, and premature turbo bearing wear. Installing a real OEM Cummins hose ensures proper heat resistance, fitment, and long-term sealing.
Compatible with VE-pump, P7100 (P-pump), VP44, and early common rail applications, the 3286499 hose features reinforced, oil-resistant rubber engineered specifically for high-temperature turbocharger drain conditions. For best results, pair this hose with new clamps and inspect both the upper drain tube and lower block elbow for wear or distortion.
