Product Description
THE MOST AGGRESSIVE FASS COMPETITION SYSTEM—540GPH @ UP TO 70 PSI. The FASS COMP540G Competition Series is purpose-built for sled pulling, dyno, and drag applications that demand massive, stable fuel delivery. It pairs extreme flow with elite filtration—removing water, air, and particulates down to 2 microns—to protect hardware at the ragged edge. Pressure is user-adjustable (0–70 PSI) via the High Flow Adjustable Regulator for precise fueling under boost. (Universal mounting bracket included; lines/wiring/fittings not included.)
- Flow: 540+ GPH free flow; maintains high volume through 10–70 PSI
- Pressure: Adjustable 0–70 PSI (High Flow Adjustable Regulator)
- Filtration: Extreme Water Separator, 2-micron absolute (3rd-party tested)
- Ports: -10 AN inlet, outlet, and regulator; 1/8" NPT gauge port
- Electrical: Each motor up to ~10 A (recommend 30 A fuse & 10-ga wiring per motor)
- Bracket: Universal mounting bracket included
Fitment & Use
Application: Universal/competition diesel fuel system for high-performance builds (race, sled pull, dyno). Not supplied with vehicle-specific plumbing or wiring. Designed to replace dual systems and reduce weight while delivering stable fuel supply for extreme HP builds.

FAQ
Q: Is the COMP540G vehicle-specific?
A: No. It’s a universal competition system. You’ll build or source your own -12 suction, -8/-10 engine feed, and return lines, plus wiring. Use the WH-1006-3R harnesses if you prefer a plug-and-play wiring solution.
Q: How much electrical current does it draw?
A: Each motor can draw up to ~10 amps. Use a 30A fuse and 10-gauge wiring per motor as recommended.
Q: What filtration does it provide?
A: Extreme Water Separator with 2-micron absolute media. It removes >99% of water (3rd-party tested) and traps particulates to protect injectors at high load.
Q: What pressure should I run?
A: The integrated High Flow Adjustable Regulator allows 0–70 PSI. Set pressure based on your fuel system/injection pump requirements and monitor with a gauge via the 1/8" NPT port.
Q: Is it easier to prime than a mechanical gear pump?
A: Yes—this unit is easier to prime than a typical mechanical gear system and is designed specifically for extreme-duty competition use.
