FAQ
Is this pump compatible with the VE (VE44) injection pump?
Yes. This RP-4G-150 system is designed for the 1989–1993 VE-pump 12-valve Cummins and plumbs directly to the factory locations.
Do I need to run a return line with the Raptor-4G?
No. The Raptor-4G pump is internally regulated and does not require a return line.
How much power will 150 GPH support?
150 GPH comfortably supports stock to moderately modified first-gens (bigger injectors/turbo, fueling tweaks). For heavy fueling upgrades, consider AirDog 4G/II-5G systems listed above.
Does it include the frame-rail bracket and hardware?
Yes. The kit includes the sandwich-plate frame mount, hardware, hose/fittings, and wiring pigtail per the install manual.
