Carter M6588

Carter M6588 is a mechanical fuel pump for selected classic Ford and Mercury carbureted engines. It is designed for low-pressure fuel systems where fuel is supplied to the carburetor by an engine-driven mechanical pump.

Application / fitment

The pump is used in selected Ford/Mercury applications from approximately 1965–1977, mainly with Ford Small Block 289 / 302 / 351W engines and selected 240 L6 engines. Compatibility should be confirmed by pump type, actuator arm, ports and fuel-line configuration.

• Ford 240 CID L6, selected applications
• Ford Small Block 289 CID
• Ford Small Block 302 / 5.0 CID
• Ford 351W Windsor
• selected Ford Mustang, Fairlane, Falcon, Torino, Maverick, Galaxie, F-Series and related models
• selected Mercury Comet, Cougar, Montego and related models

Before installation, compare the old pump with the new one: bolt spacing, actuator arm shape and length, fuel inlet, fuel outlet, thread, inlet diameter and gasket. After installation, check for leaks and fuel pressure, as excessive pressure in a carbureted system can cause carburetor flooding.
