Product Description

The AirDog R4SBD048 Raptor 4G 100 GPH Lift Pump is engineered specifically for 1994-1998 Dodge Ram 2500 and 3500 trucks equipped with the 5.9 L 12-valve Cummins diesel engine and mechanical P-pump.

Its advanced gerotor design and built-in adjustable regulator ensure smooth, continuous performance and simplified installation without the need for a return line.

Installation is made easy with the included sandwich plate mounting system, wiring harness, fuel line, and fittings. The pump's internal pressure regulation means fewer lines to run and less plumbing complexity, while its robust construction and 4G motor technology offer quieter operation and long-term durability. Ideal for stock to lightly modified Cummins trucks, the R4SBD048 delivers reliable fuel delivery and improved throttle response backed by a lifetime limited warranty.
