1. Fuel tank vent
2. Vent inlet line
3. Vent check valve
Pressurize fuel tank as follows.
PRESSURE
TIME WITHOUT
PRESSURE DROP
21 kPa (3 PSI)
3 minutes
If pressure drops, locate fuel leak(s) and repair/
replace leaking component(s).
To locate a leak, check for a fuel smell or leaking
fuel.
To ease locating leak(s), spray soapy water on all
hose connections and components; bubbles will
indicate the leak location(s).
Fuel Tank Check Valve and Pressure
Relief Valve Test
While tank is still pressurized from the previous
fuel tank leak test, carry out the following proce-
dure:
Block the vent outlet as you remove the hose
pincher.
vmr2008-135-005_a
Step 1:
Block vent outlet with finger
Step 2:
Remove hose pincher
Alternately touch and release end of pressure re-
lief valve. You should feel pressurized air flowing
out indicating relief valve is working.

PRESSURE RELIEF TEST
1. Release vent outlet and feel for air flowing out
Using the pressure/vacuum pump, increase fuel
tank pressure until the pressure relief valve opens.
NOTE:
Pressure relief valve should open when
the fuel tank pressure exceeds 2.5 - 7.6 kPa (.36 -
1.1 PSI) preventing fuel tank overpressure. This
validates pressure relief valve operation.
Remove fuel tank cap.
NOTE:
You should hear remaining air pressure
within fuel tank escape as fuel cap seal is loos-
ened.
Blow air in through vent inlet check valve.
NOTE:
Air must flow freely through inlet check
valve and out fuel tank filler neck.
