You should use a hose clamp, ensure the filter points down, secure the vent hose with a tie strap, use 5/8 in heater hose, secure it along the frame with tie straps, install the evaporative canister vent solenoid and then use 5/8 in heater hose to secure both ends with hose clamps.

You should pull back on the retaining tab, release the vent solenoid valve, disconnect the vent solenoid hose from the plastic retainers, remove the vent solenoid hose and then replace the vent hose with a bulk 5/8 in heater hose.
