Product Description
AIRDOG R4SPBF357 RP-4G-150 is a direct high-pressure replacement for the factory frame-rail pump on the 1999–2003 Ford Power Stroke 7.3L. Designed around the Raptor-4G platform, it delivers a robust 150 GPH flow with an internally adjustable regulator—no return line required. The kit mounts to the frame rail using the included sandwich plate, ties into the factory suction and feed lines, and restores consistent fuel supply for stock to moderately modified 7.3L builds.
