Choose which fuel tank your truck draws from with the Standard Ignition Fuel Tank Selector Switch, part number DS-293. It fits many vehicles, among them the 1981-1986 GMC Jimmy, 1989-1991 Chevrolet V3500 and 1987-1991 GMC R3500, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
On vehicles with more than one fuel tank, the selector switch lets the driver pick which tank is in use. Standard Ignition built this switch around the following features:
- Copper alloy conductors: used for strong electrical conductivity with low resistive losses.
- 100% tested: every switch is checked to verify both its mechanical and its electrical switching performance.
- Robust design: high-grade materials chosen to meet the stringent demands of today's service professionals.
- Technician-focused engineering: backed by decades of industry-leading research and development aimed at what technicians need.
Signs this switch may need replacing include a tank selection that does not change when the switch is moved, a fuel gauge that reads the same tank no matter the setting, or intermittent operation. The selector valve, wiring or gauge sender can cause similar symptoms, so diagnose the fault before replacing the switch.
