What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal carbureted operation
• Low fuel pressure at the carburetor
• Fuel leaks at a worn pump gasket or seal area
• Incorrect outlet connection on a replacement pump

Installation Notes and Tips

Verify the vehicle’s original pump style, inlet routing, and outlet thread size before installation. This pump uses a hose inlet and a threaded outlet, so matching the fuel line connection is important. The gasket or seal is included, but mounting hardware is not included. Confirm fitment details for notes such as without In-Cab Tank, Stock Pump, without Integral Filter, without Police Package, and without Special High Performance Engine before ordering.

Quality Assurance

Carter builds this fuel pump to match OE-style fit and function for the listed Ford and Mercury applications. The M6984 is intended for direct replacement use where the original mechanical pump configuration and fuel delivery specifications are required.
