Fuel Pressure Test; System Description - BRP Cam-am Outlander 6x6 DPS 2015 Manual

GENERAL
WARNING
Fuel is flammable and explosive under cer-
tain conditions. Ensure work area is well ven-
tilated. Do not smoke or allow open flames or
sparks in the vicinity.
WARNING
Always disconnect battery prior to working
on the fuel system.
WARNING
Always proceed with care and use appropri-
ate safety equipment when working on pres-
surized fuel system. Wear safety glasses.
WARNING
Do not allow fuel to spill on hot engine parts
and/or on electrical connectors.
When the repair is completed, ensure that all
hoses are connected and secured. Perform the

FUEL PRESSURE TEST

TEST
as explained in this subsection.
Fuel lines remain under pressure at all times.
Proceed with care when removing/installing high
pressure test equipment.
Use the B.U.D.S. software or disconnect the fuel
pump electrical connector to disable fuel pump
and crank engine to release fuel pressure prior to
disconnecting any fuel hose.
Cover the fuel hose connections with an ab-
sorbent shop rag and carefully disconnect them
to minimize spilling.

SYSTEM DESCRIPTION

Fuel Tank Vent System
The fuel tank is equipped with a vent system that
provides over pressure relief and negative pres-

FUEL TANK VENT SYSTEM
1. Vent hose
2. Vent system hose inlet
3. Vent system connected to fuel pump
4. Fuel tank
5. Engine air intake system
Air can enter the fuel tank at all times through
the vent system INLET check valve. This prevents
negative pressure within the fuel tank which could
cause fuel starvation.

AMBIENT AIR PRESSURE IN
1. Vent inlet check valve
The vent inlet check valve also prevents fuel from
flowing out through the inlet of the vent system.
If the pressure in the fuel tank builds up and
exceeds 2.5 kPa - 7.6 kPa (.36 PSI - 1.1 PSI), the
pressure relief valve opens and lets the excess
pressure evacuate through the vent system OUT-
LET hose.
