How to Replace the 1986 Toyota Van Fuel Pump

The Toyota MasterAce is a van that Toyota marketed as the Toyota Van in North American markets. This vehicle was available from 1982 to 1989. All versions of the Toyota Van in the United States had fuel-injected engines. The fuel pump in the 1986 Toyota Van is attached to the fuel sending unit on the fuel tank. This requires you to remove the fuel tank before you can replace the fuel pump.
