Detailed Product Overview

The GMB 520-8240 mechanical fuel pump is engineered for vehicles that rely on a cam-driven fuel delivery system rather than an electric pump. Its OEM standard grade supports proper fuel supply for older Chrysler, Dodge, and Plymouth platforms, including Dodge Aspen, B100, B200, and B300 models. This part cross-references Carter M60576 for the same application.

Use this pump when replacing a worn or failing mechanical unit on vehicles such as Dodge B150, Dodge B250, and Plymouth PB150/PB250 models. The 520-8240 designation is also referenced across multiple aftermarket catalogs, making it a practical service part for restoration and maintenance work.

What This Fuel Pump Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal engine operation
• Engine stalling from inconsistent pump output
• Loss of fuel pressure in carbureted systems
• Replacement of a worn mechanical pump on classic Chrysler, Dodge, and Plymouth vehicles

Because this pump is listed with no gasket required and no strainer required, confirm the mounting surface and fuel line connections are clean and in good condition before service.
