Detailed Description

The OEM standard grade supports factory-style fuel system service on applications such as the 1980-1986 Ford Bronco, 1980-1986 Ford F-150, 1979-1982 Ford Mustang, and 1979-1982 Mercury Capri. This part cross-references Airtex Fuel Pumps 60330 for the same application.

What It Helps Fix

Installation Notes and Tips

Confirm engine and chassis fitment before installation, especially on Ford E-Series and F-Series models with GVWR notes listed in the fitment data. Inspect fuel lines, mounting surfaces, and the pump actuator interface before installing the new pump. Verify that the vehicle uses a mechanical fuel pump setup and compare the original part number 525-8050 or listed interchange references before service.
