Product Description
Upgrade your 24-valve Cummins fuel supply with the AirDog II-5G DF-100 (A7SPBD253). This 100 GPH demand-flow lift pump is engineered for 1998.5–2004 Dodge Ram 2500/3500 5.9L Cummins trucks without the in-tank fuel pump. It mounts to the frame using the included sandwich-plate system, pulls fuel through a water separator, pressurizes via a gerotor pump, filters to 2 microns, and returns de-aerated fuel back to the tank for smooth, consistent pressure at the injection pump.
- 100 GPH system optimized for stock to mildly upgraded fueling
- Demand-flow design reduces heat, noise, and wear
- 2-micron post-pump filtration + water separation
- Air/Vapor return to tank for stable pressure and cleaner fuel
- Direct feed to injection pump; bypasses factory filter housing/block pump
- Complete kit with bracketry, fittings, fuel line, harness, and hardware
