Keep an accurate reading on the fuel gauge with the Agility Auto Parts Fuel Tank Sending Unit (P/N 4017232), a drop-in replacement that fits a long list of 1977-1986 Chevrolet and GMC full-size vans — including the Chevrolet G10, G20 and G30 (1977-1986) and the GMC G15, G25 and G35 (1977-1978) plus the G1500, G2500 and G3500 (1979-1986) — across L6-4.1L, L6-4.8L, V6-4.3L, V8-5.0L, V8-5.7L, V8-6.2L and V8-6.6L engines. See the Buyer's Guide tab for the full application list.
The sending unit uses an in-tank float and variable resistor to track how much fuel is in the tank and relays that signal to the dash fuel gauge. If a worn or erratic original sender is the cause of a gauge that reads inaccurately, sticks, or drops out, this replaces it.
