Detailed description
Delphi FT4026 is a standard replacement fuel transfer unit engineered for specific right-side applications in the Cadillac XLR and Chevrolet Corvette. It uses a 4-terminal male blade connection, a quick-connect outlet, and a 0.375-inch outlet outside diameter. The sender resistance range is 40.0 ohms empty to 250.0 ohms full, supporting accurate fuel level reporting.
Delphi draws on more than 100 years of OE experience and long-standing supplier relationships with major automakers. That OE heritage is reflected in the FT4026 fuel transfer unit, part number FT4026, which is built for service work where the original fuel delivery and level-sensing functions need to be restored.
This part cross-references Airtex Fuel Pumps E3579M for the same application.
Common replacement issues
- Fuel level reading errors or an inoperative gauge
- Fuel delivery problems caused by a worn in-tank module
- Seal leakage at the tank opening during pump service
- Faults related to the regulator or vapor pressure sensor
Installation notes and quality
Clean the fuel tank before installation to reduce the risk of contamination-related pump failure and seal problems. For the 2003 Chevrolet Corvette application, a fuel tank cleaning kit is recommended in the fitment notes. Verify the right-side application, outlet style, and electrical connection before installation.
Delphi FT4026 is a standard replacement part backed by OE heritage and broad aftermarket coverage across multiple vehicle years.
