Fuel Tank: Description and Operation

Fuel Tank:

The fuel tank is located in the rear of the vehicle and is used to store the fuel supply. The fuel tank is made of steel and is coated internally with a special corrosion inhibitor. Due to the internal coating of the fuel tank, the fuel tank is not repairable. In order to maintain a constant supply of fuel around the fuel pump strainer during low fuel conditions and aggressive vehicle maneuvers, the fuel tank shape includes a reservoir. A filler pipe check-valve tube is attached to the fuel tank and extends from the fuel tank inlet to the reservoir. The filler pipe check-valve is located inside the filler pipe check-valve tube and prevents fuel from splashing out of the fuel tank filler pipe during refueling.

The tank also contains a fuel vapor vent valve with roll-over protection. The vent valve also features a two phase vent calibration which increases fuel vapor flow to the canister when operating temperatures increase the tank pressure beyond an established threshold.
