The BD Diesel Flow-Max Lift Pump/Fuel System for the 2003-2004 5.9L Cummins is built with a proven gerotor design that flows 150 gallons per hour (GPH) that can supply your truck with enough fuel for more than 600 horsepower. This ultra quiet and compact Flow-Max lift pump utilizes vibration isolators along with aluminum brackets and stainless straps for quick and versatile mounting on the frame rail. No drilling is required!

The fully modular design allows for the addition of a water separator and high efficiency low-micron filters using non-proprietary cartridges that can be purchased at most auto parts retailers converting your Flow-Max from a standard Lift Pump to a full fuel system comparable to Air Dog or the FASS Titanium Series. The Flow-Max is an ideal replacement for the OEM pump which is known to fail at even stock horsepower levels.

Note: Vehicles with intank lift pump conversion require the Flow-Max retrofit kit.
