This vehicle uses a saddle type tank, a reservoir on both sides of the rear drive shaft. The fuel pump is in the module on the left side of the vehicle and the fuel pressure regulator is in the module on the right side of vehicle. The fuel outlet is on the right side and supplies fuel to the engine. The fitting on the fuel pump module (left side) is a vapor line fitting that connects to the right side module. Both modules have fuel level sending cards. There are 2 hoses that connect the modules together, one is the fuel supply line the other is a return or siphon hose. The lines are removed from the fuel pump module when servicing either unit. The ORVR (On-Board Refueling Vapor Recovery) control valve is in the right side module.
