FUEL PUMP MODULE
DESCRIPTION
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 driver side of the vehicle and the
fuel pressure regulator is in the module on the pas-
senger side of vehicle. The fuel outlet is on the pas-
senger side and supplies fuel to the engine. The
fitting on the fuel pump module (Driver side) is a
vapor line fitting that connects to the passenger 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
(Onboard Refueling Vapor Recovery) control valve is
in the passenger side module.
OPERATION
The way the pump works is as follows, fuel enters
the reservoir of the driver side module. The fuel
pump pumps the fuel through the filter to the pas-
senger side module through a supply line inside
tank. The pressure regulator inside the passenger
side module regulates the pressure at 58 psi. All
unused fuel that is not sent to the engine is fed
