Product Description
Airdog A4SPBD136 FP-100-4G is a 100 GPH air/fuel separation system engineered for the first-gen 1989–1993 Dodge Ram Cummins 5.9L 12-valve with the VE pump. It mounts to the frame rail with the included sandwich-plate bracket, pulls fuel through the factory suction line, sends clean, de-aerated fuel directly to the VE injection pump, and returns air/vapor to the tank via the filler neck tee. This kit is ideal for stock-to-moderate builds that want steadier pressure, reduced cavitation, and longer injector pump life. Installation manual link below.

Installation Instructions
FAQs
What power level is the FP-100-4G best for on a 1989–1993 VE Cummins?
It’s designed for stock to moderate builds where 100 GPH supply stabilizes pressure and reduces aeration to protect the VE pump.
Does it replace my factory fuel filter housing?
Yes—this system routes clean fuel directly to the injection pump, bypassing the factory filter housing and pump.
Do I need to drop the tank for install?
No. It mounts on the frame rail with the included bracket, uses the factory suction line, and returns air/vapor to the tank via a filler neck tee.
Can I pair this with injectors and a mild turbo upgrade?
Yes. For higher demand, consider the FP-150-4G (A4SPBD137); for stock trucks wanting a simpler supply pump, see the Raptor RP-4G options above.
