FAQ
Will the A7SABF594 replace my factory frame-rail lift pump?
Yes. This II-5G DF-165-5G system mounts on the frame rail and fully bypasses the factory pump while connecting to the OEM supply/return lines with quick-connects.
Is DF-165 enough for tuned injectors and basic performance mods?
For stock to moderately tuned 6.4L builds, DF-165 is ideal. If you’re targeting higher fuel demand (big singles/compounds, heavy fueling), step up to the DF-220-5G.
Which filters come on the pump and what do I replace them with?
The II-5G ships with a fuel filter and water separator. Replace with FF100-2 (2-micron) or FF100-10 (10-micron) and the WS100 water separator as needed.
Do I need to drop the tank?
No tank drop is typically required. The system draws from the factory suction line on the frame rail and returns through the OEM return/Y—follow the install manual for details.
