Fuel Pump Test - Polaris RANGER XP 900 2013 Manual

FUEL SYSTEM - GENERAL

FUEL PUMP TEST

If a fuel delivery problem is suspected, make certain the
fuel pump filter is not plugged, that the pump is being
activated through the ECU, all electrical connections are
properly secured, the fuses are good, and a minimum of
7.0 volts is being supplied. If during starting the battery
voltage drops below 7.0 volts, the ECU will fail to operate
the system.
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
around fuel or fuel vapors.
1. Couple Fuel Pressure Gauge Adapter (PS-48762) to
the Fuel Pressure Gauge Kit (PU-43506-A).

4. Remove the black plastic cap and attach the fuel
pressure gauge adaptor to the pressure valve. Route
the 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 fuel pressure is
within specification, the ignition switch, ECU, fuel
pump and pressure regulator are working properly.
Turn the key switch off and turn the relief valve on
the tester to relieve the system pressure.
Fuel Pressure: 58 ± 2 psi (400 ± 14 kPa)
If the fuel pressure is out of specification, replace the
fuel pump assembly.
