WARNING
Fuel is extremely flammable and may cause severe
burns, injury, or death. Do not use any device that
produces a flame or electrical devices that may spark

1. Remove the passenger seat from the vehicle.
2. Cover the fuel line connection at the fuel tank with a
shop towel and disconnect the line from the fuel
pump outlet.
3. Install the Fuel Pressure Gauge Adapter (PV-48656)
in-line between the fuel pump outlet and fuel line.
4. Connect the hose from the Fuel Pressure Gauge Kit
(PU-43506-A) to the test valve on the Fuel Pressure
Gauge Adapter (PV-48656). Route clear hose into a
portable gasoline container or the vehicle’s fuel tank.
