-8AN Fuel Inlet Fitting

The -8AN Fuel Inlet Fitting from HOLLEY is a precision adapter designed for high-performance fuel system applications where reliable, leak-free connections are non-negotiable. This straight-configuration fitting bridges 8 AN male ports to 7/8-20 inch male threads, making it essential for custom fuel systems, racing platforms, and aftermarket carburetor installations. Whether you're upgrading a street rod, competition vehicle, or performance engine build, this adapter ensures proper fuel delivery without compromise.

Manufactured from aluminum and finished in blue anodize, the -8AN Fuel Inlet Fitting combines corrosion resistance with lightweight durability—critical factors in fuel system environments where oxidation can degrade performance over time. The washer-sealed design creates a secure mechanical bond that resists vibration and thermal cycling, preventing leaks under pressure. HOLLEY's AN fitting standard ensures compatibility across industry-standard fuel lines and components, while the straight orientation allows flexible routing in tight engine bays without complex bend configurations that could restrict fuel flow.

This fitting is ideal for installers and builders integrating HOLLEY fuel systems, aftermarket EFI conversions, or custom carburetor setups requiring AN-to-NPT adapter solutions. The compact 3.5 x 1.15 x 4.95 inch profile and minimal 0.05 lb weight make it suitable for engine compartments where space is limited. Installation requires standard wrench sizes and hand-tight assembly techniques—proper torque spec adherence prevents damage to the anodized finish and ensures long-term seal integrity across seasonal temperature variations and prolonged storage.
