To replace the fuel pump on a 1986 Astro Van, first disconnect the battery and relieve fuel system pressure. Remove the fuel tank by unbolting it from its supports and disconnecting the fuel lines and electrical connections. Once the tank is removed, access the fuel pump by removing the retaining ring on the top of the tank, then replace the old pump with the new one, ensuring all seals and gaskets are in place. Finally, reassemble the tank, reconnect the lines, and test the system for leaks before starting the vehicle.
