Delphi Fuel Tank Sending Unit P/N:FL0448
Delphi FL0278 right fuel tank sending unit for the 2005-2009 Ford Mustang V6 4.0L or V8 4.6L and the 2007-2009 Mustang V8 5.4L reads the fuel level in the tank and passes it to the gas gauge. This Delphi fuel tank sending unit is built to Delphi's OE standards.
A gas gauge that reads wrong, jumps around or sticks on empty or full can be a sign the sending unit is failing. Before you replace it, rule out the gauge wiring and a dirty fuel tank, since a wrong reading can come from more than one place.
This sending unit fits the 2005-2009 Ford Mustang V6 4.0L or V8 4.6L and the 2007-2009 Mustang V8 5.4L. The listing is one sending unit for the right side, and that position takes one.
