Fuel Pump Gasket

The fuel pump gasket (model 5182) is a precision composite mounting plate engineered for Small Block Chevy fuel pump assemblies. This gasket serves as a critical sealing component between the fuel pump and its mounting surface, preventing fuel leakage and maintaining system integrity under operating pressure. Whether you're rebuilding a classic Chevy engine, performing routine fuel pump maintenance, or restoring a vintage muscle car, a quality gasket replacement is essential to reliable fuel delivery and engine performance.

Constructed from composite material at 0.022 inches thick, this fuel pump gasket provides optimal compression and durability without the brittleness of older cork designs. The composite construction resists fuel degradation, maintains consistent sealing pressure across thermal cycles, and compresses evenly under the mounting plate load to create a reliable, long-lasting seal. The gasket's compact footprint (measuring 4.4 x 0.3 x 7 inches) ensures proper fit within the fuel pump assembly cavity while its minimal weight (0.02 lbs) poses no stress on mounting hardware or fasteners.

Small Block Chevy owners—from vintage car enthusiasts to street rod builders—rely on gasket replacement as preventive maintenance during fuel pump service. Installation is straightforward: simply position the gasket between the fuel pump body and mounting plate, ensuring even seating before torquing fasteners in a star pattern to prevent uneven compression. This gasket is the ideal choice for those seeking OEM-quality sealing at accessible pricing, whether as a replacement for failed units or as a preventive upgrade during engine rebuild projects.
