End Cap -20AN Inlet w/ -10an Accessory Port

The End Cap -20AN Inlet w/ -10an Accessory Port is a precision fuel filter manifold component designed for high-performance fuel system applications. This aluminum end cap serves as a sealed inlet point for Peterson 400 Series fuel filters, directing fuel flow while providing an auxiliary -10AN port for secondary accessories such as fuel pressure gauges, bypass fittings, or distribution blocks. Professional mechanics and performance enthusiasts rely on this component to create organized, leak-free fuel delivery systems in race vehicles, street rods, and custom powerplants where plumbing flexibility is essential.

Manufactured from aluminum and finished in red anodizing, the end cap offers both corrosion resistance and visual identification within complex fuel systems. The -20AN male inlet connection accommodates 1.25-inch hose or hard-line fittings, providing a robust seal rated for typical fuel system pressures, while the -10AN accessory port allows installation of auxiliary fuel system components without requiring additional manifold blocks. The red anodized finish protects against oxidation in harsh engine compartment environments and simplifies system assembly by color-coding primary fuel flow paths, reducing installation errors during fuel system construction or troubleshooting.

This end cap is ideal for builders integrating Peterson 400 Series fuel filter housings into custom fuel systems requiring modular inlet and accessory configurations. The combination of a primary -20AN inlet and secondary -10AN port eliminates the need for separate manifold blocks, reducing system complexity and weight. Installation requires AN-compatible hose or hard-line tubing and standard AN wrenches; ensure all connections are properly sealed with appropriate thread sealant to prevent fuel leakage. Weighing just 0.4 pounds, this compact component is suitable for carbureted engines, EFI systems, and fuel cell applications where space and weight optimization matter.
