ProForce blowers with serial number above 310000000
are equipped with a fuel evaporative control system
(EVAP) designed to collect and store evaporative emis-
sions from the fuel tank. The EVAP uses a carbon canis-
ter to collect these evaporative emissions. Fuel vapors
from the fuel tank are vented to the canister where they
are stored. Vapors from the canister are consumed
when the engine is running which purges the canister.
The fuel tank on these ProForce machines uses a non--
vented fuel cap. To connect the tank to the evaporative
control system, a fuel vent valve is positioned in the top
of the tank that allows tank venting through the carbon
canister.
NOTE: If there is restriction in the fresh air filter, the car-
bon canister or the fuel vent valve, the fuel tank may dis-
tort due to venting issues. If the fuel tank returns to it’s
normal shape when the fuel cap is removed, restriction
in the evaporative control system is likely.
Machines with a carbon canister include a single engine
connection to the engine intake system that is used to
connect the evaporative system to the engine. These
machines use an inline check valve and fuel filter
between the carbon canister and the engine fitting.
Evaporative control system components for ProForce
blowers are shown in Figure 11.
