Detailed description

This Airtex mechanical fuel pump, part number 60577, is engineered for older Dodge and Plymouth applications that use an external mechanical pump. Fitment includes a wide range of Dodge D100, D200, D300, W100, W200, and W300 trucks and pickups, along with Plymouth Barracuda, Valiant, Fury, and Satellite models across multiple years. It also covers many classic Dodge van and passenger-car applications, making Airtex 60577 a direct replacement choice for restoration and maintenance work on carbureted fuel systems. This part cross-references Carter M60577 and Delphi MF0018 for the same application.

The pump uses a hose-style inlet, threaded outlet, and a 5/16 inch inlet thread size with a 1/2-20 UNF outlet thread size. Airtex 60577 is factory tested for consistent output and is intended for external mounting on vehicles that match the listed fitment, including Dodge Dart and Plymouth Fury applications. A new fuel filter is recommended when replacing the pump.

What it is used for

• Fuel delivery issues caused by a worn mechanical pump
• Hard starting from insufficient fuel supply
• Fuel starvation under normal driving conditions
• Restoration of carbureted fuel systems on classic Dodge and Plymouth vehicles
• Replacement of a leaking external fuel pump

Installation notes and quality assurance

Verify the vehicle’s emissions configuration before ordering, since some listed applications exclude California emissions or evaporative emission setups. Confirm hose and thread connections against the existing pump before installation. Replace the fuel filter during service and inspect fuel lines for wear or contamination. Airtex tests every pump throughout the manufacturing process to support out-of-the-box performance.
