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.
Fuel Gauge Adapter (RZR 900): PV-48656
Fuel Gauge Adapter (RZR S 1000): PA-48838
4. Connect the hose from the Fuel Pressure Gauge Kit
(PU-43506-A) to the test valve on the Fuel Pressure
Gauge Adapter. Route clear hose into a portable
gasoline container or the vehicle's fuel tank.
5. Turn on key switch to activate the pump and check
the system pressure on the gauge. If system pressure
of 58 ± 2 psi (400 ± 14 kPa) is observed, the ignition
switch, ECU, fuel pump, and pressure regulator are
working properly. Turn the key switch off and depress
the valve button on the tester to relieve the system
pressure.
Fuel Pressure:
58 ± 2 psi (400 ± 14 kPa).
NOTE
If the fuel pressure is out of specification, replace the
fuel pump assembly.

6. If the pump did not activate (Step 5), disconnect the
harness connector from the fuel pump. Connect a DC
voltmeter across terminals "3" and "4" in the plug on
the vehicle fuel pump harness. Turn on the key switch
and observe voltage to ensure a minimum of 7 volts is
present.
If the voltage was below 7 VDC, test the battery, ignition
switch, relay(s), wiring harness and ECU.
7. If the reading is between 7 and 14 volts, turn key
switch off and connect an ohmmeter between
terminals "3" and "4"' at the white fuel pump
connector to check for continuity within the fuel pump.
If there was no continuity between the pump terminals,
8. If voltage at the plug was within the specified range,
and there was continuity across the pump terminals,
reconnect the plug to the fuel pump, making sure you
have a clean connection. Turn on the key switch and
listen for the pump to activate.
If the pump starts, repeat steps 3, 4 and 5 to verify
9. If the pump still does not operate, check for correct
ECU operation by plugging in a known-good ECU of
the same model.
If the pump still does not operate, replace the fuel pump
