Abstract
A method of defueling a vehicle having a fuel tank, an electric fuel pump includes connecting a hose to the fuel system downstream of the fuel tank and electrically connecting the fuel pump to the battery. In a multiport fuel injected engine, the hose connection is to the fuel pressure gauge test point. In a throttle body fuel injection unit, the injector is removed and a dummy injector having an outlet is installed.
