Detailed Description

This GMB fuel pump and sender assembly is engineered for 1987-1989 Ford F-150, Ford F-250, and Ford F-350 models with a center fuel tank and 19 gallon fuel tank configuration. It combines fuel pump and sending unit functions in one assembly, helping restore proper fuel delivery and fuel gauge operation in the specified truck applications. If you are sourcing a replacement for a Ford F-150 fuel pump and sender assembly or a Ford F-350 center tank fuel sender, 525-6410 is a direct reference point for the listed fitment.

As an OEM standard replacement, this part is built around factory-level specifications rather than a universal design. The no-gasket-required attribute simplifies parts selection for the application, while the OE-style construction supports consistent fitment in the original tank setup. Part number 525-6410 also cross-references Airtex E2103S for the same application.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel gauge readings that do not match tank level
• Intermittent engine stalling related to fuel supply issues
• Loss of fuel pressure in center tank applications
• Replacement needs for worn pump and sender components

Installation Notes and Tips

Verify the vehicle year, model, and tank configuration before ordering. This assembly is listed for center fuel tank applications with a 19 gallon fuel tank on 1987-1989 Ford F-150, F-250, and F-350 trucks. Confirm the existing tank setup and compare the original part number, including 525-6410, before installation. Because no gasket is required, do not add an unlisted gasket unless the vehicle service procedure specifically calls for one.

GMB manufactures this assembly to meet or exceed OEM specifications and supplies it as an OEM standard replacement part. That specification-based approach supports consistent fitment and function for the listed Ford truck applications.
