Keep your fuel gauge reading true with the Spectra Premium Fuel Tank Sending Unit (MPN FG17D). This is a direct-fit replacement for a broad run of GM full-size vans: it fits the 1977-1986 Chevrolet G10, 1977-1986 Chevrolet G20, and 1977-1988 Chevrolet G30, along with the 1977-1978 GMC G15, 1979-1986 GMC G1500, 1977-1978 GMC G25, 1979-1986 GMC G2500, 1977-1978 GMC G35, and 1979-1988 GMC G3500.
- Level-sensing job: a float rides on the fuel surface and moves an arm that varies electrical resistance, sending the signal your dash fuel gauge reads.
- Direct-fit replacement: a direct-fit replacement for the listed Chevrolet and GMC applications.
- Replacement for worn originals: if a failed sending unit is the cause of an erratic, stuck, or inaccurate gauge, this replaces it.
Signs the original sending unit may need replacing include a fuel gauge that reads full or empty at the wrong times, sticks, jumps, or stops moving. Diagnose the cause before replacing, since gauge, wiring, and ground faults can produce similar symptoms.
