Fuel Reservoir: Description and Operation
The Fuel Reservoir is located under the rear of the vehicle mounted to the same bracket as the fuel pump and fuel filter. The fuel inlet portion of the main
fuel pump is mounted inside the fuel reservoir for direct access to the fuel stored in it. The fuel reservoir is used to receive fuel from the transfer pump
inside the fuel tank, then supply fuel to the main fuel pump for pressurization.
