Fuel Tank Sending Unit Overview

The Spectra FG11G fuel tank sending unit is built for select 1986-1987 GM compact cars with the original fuel tank configuration. It restores fuel level signal function for applications that use a standard gauge setup, and one listed Chevrolet Cavalier application with a digital gauge.

The FG11G is identified by part number FG11G and is cross-referenced to Monroe Shocks & Struts 25091315 and 25092098 for the same application.

Installation Notes and Tips

Verify the gauge type and application notes before installation, especially for the 1986 Chevrolet Cavalier listing with a digital gauge.
