Fuel Pump 400 Ultra Light No Mount

The Waterman Racing Comp WRC-22108 Fuel Pump 400 Ultra Light No Mount is a hex-driven, high-flow fuel delivery system engineered for dedicated race and performance applications. This aluminum fuel pump handles gasoline, methanol, and E85 fuels, making it versatile across multiple fuel programs. With a 0.400 gear set and in-line configuration, the unit pairs 8 AN female inlet and outlet fittings for straightforward integration into custom fuel systems. The black anodized finish provides corrosion resistance in high-heat engine bays, while the no-mount design gives fabricators complete freedom in pump placement and bracket configuration.

Weighing just 1.56 pounds, the WRC-22108 exemplifies the weight-reduction philosophy central to competitive racing. The ultra-light construction directly impacts overall vehicle weight without compromising flow rate or durability. The 0.400 gear set specification determines displacement and fuel pressure characteristics—critical parameters that must match engine fuel rail demand and carburetor or fuel-injection system requirements. Proper sizing ensures adequate fuel supply under wide-open throttle and sustained high-RPM operation without excessive pressure that could damage regulators or injectors. The hex-driven design allows flexible coupling options to electric motors or mechanical drives depending on ignition system architecture and fuel system design.

This fuel pump is purpose-built for competitors, fabricators, and engine builders investing in custom fuel systems for drag racing, circle track, off-road competition, or high-displacement naturally aspirated and forced-induction platforms. The no-mount configuration appeals to builders requiring compact engine bays or unconventional fuel cell placements where OEM-style mounting brackets won't integrate. Multi-fuel compatibility—handling E85's corrosive nature, methanol's solvency, and traditional gasoline—ensures the pump performs across varied fuel programs without material degradation. Builders selecting this unit should verify flow capacity (in gallons per hour) and maximum operating pressure against their fuel system demand calculations and component ratings to ensure proper system matching.
