Manifold 4 Port For WRC Pumps

The Manifold 4 Port For WRC Pumps is a precision-engineered fuel distribution component designed for high-performance racing and custom fuel system applications. Manufactured by Waterman Racing Comp., this aluminum manifold consolidates multiple fuel pump outlet lines into a single, organized connection point, making it an essential component for complex fuel delivery architectures in modified vehicles and racing engines.

The manifold features four 6 AN male outlets, providing the standard SAE 6 AN port configuration widely used in performance fuel system plumbing. The black anodized aluminum construction offers excellent corrosion resistance and durability under the demanding conditions of fuel system applications—where exposure to fuel additives, moisture, and temperature cycling can degrade unprotected materials. Anodizing also prevents galvanic corrosion when the manifold interfaces with different metals in the fuel system. At 0.3 lbs and measuring 3.35 x 2.4 x 8.3 inches, the compact design integrates cleanly into tight engine bay layouts while maintaining robust port capacity for fuel flow requirements in multi-pump setups.

This fuel pump manifold is ideal for builders working with Waterman Racing Comp. fuel pumps or equivalent systems requiring consolidated outlet distribution. Common applications include custom fuel rail systems in drag racing, circle track racing, and street performance builds where multiple fuel pumps feed a single fuel rail or distribution block. The four-port design accommodates single-pump configurations with extra ports for future expansion, or multi-pump setups where redundancy and system pressure balancing are critical.

6 AN fittings have become the industry standard in performance fuel systems because they minimize turbulence and pressure drop compared to smaller port sizes, supporting reliable fuel delivery at high flow rates. Proper manifold selection ensures that fuel distribution does not become a restriction point in the overall system, particularly in engines requiring 400+ hp where fuel delivery becomes a precision engineering detail rather than an afterthought.

Each manifold ships as an individual unit and does not include hoses, fittings, or end plugs—plan accordingly for your complete fuel system assembly.
