Product Description
Airdog A4SPBD101 FP-100-4G is a 100 GPH original AirDog system for 1998.5–2004 Dodge Ram Cummins 5.9L 24-valve trucks without the in-tank fuel pump (VP44 and early CP3). It mounts to the frame rail with the supplied sandwich-plate bracket, draws from the factory sending unit, feeds clean, de-aerated fuel directly to the VP44/CP3, and returns air/vapor to the tank via a filler-neck tee for steadier pressure and longer pump life.

Installation Instructions
FAQs
Is 100 GPH enough for mild injectors/tune?
Yes. FP-100-4G supports typical street builds. For more headroom, choose the FP-150-4G (A4SPBD104).
Does this replace my factory lift pump and filter housing?
Correct—this kit feeds the VP44/CP3 directly, bypassing the OE block-mounted lift pump and filter base.
Do I have to drop the tank?
No. It mounts on the frame rail; air/vapor returns via a filler-neck tee using the included hardware.
Which trucks use the “without in-tank pump” kit?
VP44 (1998.5–2002) and some early 2003–2004 CP3 trucks that still rely on the block-mounted pump.
