FAQ
Is DF-220-5G overkill for a stock LML?
Yes — 220 GPH is aimed at high-horsepower builds. For stock or lightly modified trucks, consider the 165 GPH (A7SABC510) or 100 GPH (A7SPBC260) systems listed above.
Does this replace the CP4 injection pump?
No. This is a frame-mounted lift pump and air/fuel separation system. It supplies clean, de-aerated fuel to the factory high-pressure pump.
Does it work with factory quick-connect lines?
Yes. The kit interfaces with factory lines and returns separated air/vapor back to the tank as part of the design.
