The canister cycles the fuel vapor from the fuel tank. The activated charcoal element within the canister acts as a storage device for the fuel vapors at times when the engine operating conditions do not allow efficient burning of the vapors.
The only required service for the canister is inspection at the intervals specified in the Maintenance Chart at the end of this section. If the charcoal element is saturated, the entire canister will require replacement. Label and disconnect the canister purge hoses, loosen the retaining bracket bolt(s) and lift out the canister. Installation is simply the reverse of the removal process. To check the canister:
- Label and remove the vacuum lines leading to the canister.
- Unfasten the retaining bolts from the canister.
- Pull the lower hose off the tube attached to the lower portion of the canister.
- Inspect the case for any cracking or damage.
- Using low pressure compressed air, blow into the tank pipe (flanged end) and check that air flows freely from the other ports.
