FUEL FILTER OUTPUT CAP
Multiple Variants | Anodized Aluminum | E85 Compatible

The Precision Raceworks Fuel Filter Output Cap is the perfect finishing piece for your custom fuel filter assembly. Crafted from high-quality anodized aluminum, this cap offers a durable and versatile solution for high-performance fuel systems using E85 or pump gas.

Whether you're routing to your fuel rail or sealing off the end of your filter for a returnless or remote-feed setup, we have a configuration to meet your needs. Like all Precision Raceworks components, this cap is built to handle the demands of high-horsepower applications while maintaining OEM-style reliability.

Available Variants:

  • AN8 ORB Output – Standard high-flow outlet for return or feed line routing

  • AN8 ORB with Integrated Check Valve – Prevents fuel drain-back for consistent pressure on startup

  • Flat Cap (No Output) – Designed for use with input-side regulated return systems (e.g., AN6 Input to AN6 Output cap)
