The engine fuel system consists of a multi-section fuel tank, fuel lines, fuel filter, fuel pump and fuel injection system.
The fuel tank is located under the bottom at the rear of the vehicle. The fuel tank is ventilated through a closed air removal system. Fuel vapors are captured by a canister with activated carbon - an adsorber
