Section 04 FUEL SYSTEM
Subsection 02 (FUEL TANK AND FUEL PUMP)
Test when Engine Is Stopped
1. Remove tether cord from the engine cut-off
switch to prevent engine starting.
2. Press the START button and observe fuel pres-
sure.
3. Release pressure in system using the valve on
the pressure gauge between each test so that
the reading returns to zero (0).
4. Repeat test twice and compare readings to
specifications in following table.

FUEL PUM
P PRESSURE TEST
1. Valve on gauge
FUEL PRESSURE
(WHEN PRESSING THE START BUTTON)
386 kPa - 414 kPa (56 PSI - 60 PSI)
Test when Cranking or Starting Engine
1. Crank or start engine and observe fuel pres-
sure. The fuel pressure should be the same as
in previous test.
If pressure is good, fuel pump a nd pressure regu-
lator are functioning correctly.
2. Stop the engine.
A rapid pressure drop indicates leakage either
from the fuel rail or from the fuel pump check
valve. Check fuel rail for leaks.
If a pressure drop occurs when pressing the
START button and the fuel rail is not leaking, then
replace the fuel pump module.
A slow pressure drop indicates leakage either
from a fuel injector or from the fuel pressure
regulator in the fuel pump module. To check
fuel injectors for leaks, refer to the
ELECTRONIC
FUEL INJECTION (EFI)
subsection. If injectors
are not leaking, then replace fuel pump.
3. Release fuel pressure in system using the valve
on the pressure gauge.
4. Remove pressure gauge and reinstall fuel hose
on fuel pump module.
WARNING
Wipe off any fuel spillage in the bilge. Fuel
is flammable and explosive under certain
conditions. Always work in a well ventilated
area.
5. Reinstall all other removed parts, refer to appli-
cable subsections.

FUEL HOSES AND OETIKER
CLAMPS
Inspecting Fuel Hoses
1. Inspect all fuel hoses for wear, kinks, cracks or
any other types of damages.
2. Inspect a
ll clamps for tightness.
Replacing Fuel Hoses
When repl
acing fuel hoses, be sure to use hoses
and clam
ps as available from BRP parts depart-
ment. Th
is will ensure continued proper and safe
operati
on.
WARNING
Use of fuel lines other than those recom-
mended by BRP may compromise fuel sys-
tem integrity.
