Fuel Pump Block-Off Plat

The MR. GASKET Fuel Pump Block-Off Plate for big block Chevy engines is a precision-engineered component designed for builders converting carburetor-fed fuel systems or eliminating electric fuel pump circuits in modified engines. This steel block-off plate serves as a direct, no-nonsense solution for sealing off the factory fuel pump mounting location when transitioning to alternative fuel delivery methods or mechanical fuel pump configurations. Whether you're restoring a classic big block, simplifying engine bay wiring, or reducing parasitic load from unnecessary electric fuel pumps, this plate provides a clean, OEM-style integration point.

Manufactured from durable steel with a chrome-plated finish, the MR. GASKET block-off plate resists corrosion and maintains a polished appearance in engine compartments subject to heat cycles and moisture exposure. The compact design—measuring 4.1 inches in length and 6.1 inches in width—fits within the standard big block Chevy fuel pump mounting envelope, ensuring proper clearance and secure fastening. Chrome plating not only protects against rust and oxidation but also reflects heat away from critical engine components, contributing to thermal management in high-output builds. At just 0.21 lbs, the plate adds negligible weight while providing structural integrity and a sealed mounting surface.

This block-off plate is ideal for big block Chevy engine swaps, vintage drag racing restorations, and custom carburetor conversions where eliminating the electric fuel pump circuit simplifies wiring harnesses and reduces electrical draw. Installation requires standard fasteners that mate with the original big block fuel pump boss, making removal and replacement straightforward for experienced mechanics. The chrome finish pairs seamlessly with show-quality engine builds while delivering practical functionality in street and competition applications. Verify fitment with your specific big block Chevy variant and fuel system configuration before ordering to ensure compatibility with your fuel delivery setup.
