Pro Force debris blowers are equipped with a fuel evaporative control system
designed to collect and store evaporative emissions from the fuel tank. The
evaporate control system uses a carbon canister and a series of vent hoses to
collect these evaporative emissions. The fuel tank uses a non-vented fuel cap. A
fuel tank vent/rollover valve is positioned in the top of the tank that allows tank
venting through the carbon canister. Fuel vapors from the fuel tank are vented to
the canister and consumed by the engine when the engine is running.
Note:
If there is restriction in the carbon canister, the fuel tank vent fitting or the
vent hose, the fuel tank may distort 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.
The carbon canister is mounted on the control tower/battery box. The
evaporative system connection to the engine passes through a filter and a
vacuum check/purge valve before connection to the engine intake manifold. The
evaporative control system vent connection passes through a fresh air filter
before it reaches the carbon canister.
