To replace the fuel transfer switch in a 1990 Ford F-150, first, disconnect the vehicle's battery to ensure safety. Locate the fuel transfer switch, typically found near the fuel tank or under the driver's seat, and remove any necessary panels for access. Disconnect the wiring harness and remove the switch from its mounting. Install the new switch by reversing the process, reconnecting the wiring, and ensuring everything is properly secured before reconnecting the battery.
