Description
Product Overview
The AUTOVIC Braided Oil Supply Hose is engineered specifically for heavy‑duty Ram 2500 and 3500 trucks equipped with the 5.9L 24V Cummins diesel engine produced between 1998 and 2002. Measuring 7.87 inches in length and 1.96 inches in width, the hose features a robust braided outer layer that encases a flexible synthetic rubber core. This construction delivers exceptional resistance to corrosion, abrasion, and high‑temperature oil exposure, ensuring a long service life even in demanding environments. The part number DD-59L-VPOL matches OEM specifications, allowing a direct, bolt‑for‑bolt replacement of ruptured or worn oil lines without the need for additional adapters. Weighing only 2.4 ounces, the hose is lightweight yet built to handle the pressures typical of fuel injection systems.
Usage

The hose is intended for use in the fuel injection oil supply circuit of Ram 2500/3500 trucks with the 5.9L Cummins diesel. It is ideal for both professional service centers and DIY enthusiasts who need a reliable replacement for a cracked or leaking oil pipe. Installation requires standard hand tools and takes only a few minutes, making it suitable for routine maintenance, emergency repairs, or performance upgrades. The hose performs optimally in a range of conditions—from hot summer days to cold winter mornings—thanks to the synthetic rubber’s flexibility and the braid’s structural integrity.
