Spectra FG12J Premium Fuel Tank Sending Unit with Strainer and Float

The Spectra Premium FG12J is a direct-fit, electrically operated fuel tank sending unit engineered to restore accurate fuel level readings on GM C/K trucks equipped with the 6.2L diesel engine. Designed to match original equipment specifications, this sending unit installs without modification and connects directly to the factory wiring harness.

Key Features:

• OE-Matched Electrical Connections: Plug-and-play connector fits the factory harness for a straightforward, no-splice installation
• Sender Ohm Range: 0 ohms at empty / 95 ohms at full — calibrated to work correctly with the OE fuel gauge
• Feed Line: 3/8 in. outlet (butt flare) with a 1/4 in. inlet (butt flare) matching factory line sizing
• Includes Strainer: Pre-installed strainer supports a clean fuel system on replacement and simplifies the installation process
• Float Included: Float assembly included where the original equipment featured one
• Complete Hardware Kit: Comes with a new lock ring, O-ring, and all terminals and connectors — everything needed for a complete installation
• POM Construction: Polyoxymethylene (POM) material used throughout the fuel module assembly including the connector, rheostat housing, and inlet/outlet tubes for superior fuel resistance and long-term durability
• Carbon Commutator Design: Carbon commutator (versus copper on early OE units) provides longer service life and improved resistance to corrosive fuel blends
• Engineered to OE Tolerances: Developed with in-depth knowledge of the original part it replaces to meet or exceed OEM performance standards

The Spectra Premium FG12J is sold individually and is engineered for a precise, trouble-free replacement of a faulty or failing factory sending unit, helping restore accurate fuel level monitoring and protecting the fuel system.
