NOTICE:
When replacing the canister, check the canister
pump module interior and related pipes for water,
fuel and other liquids. If liquids are present, check
for disconnections and/or cracks in the following: 1)
the pipe from the air inlet port to the canister pump
module; 2) the canister filter; and 3) the fuel tank
vent hose.
