T
he canisters are fixed to the underside of the vehicle either
directly or via semi-enclosed mounting brackets. Two fixing
bolts are used at the front of the canister(or bracket) and a single rear bolt supports the canister and the canister close
valve (CCV).
The vapour pipes to the canisters, other than the CCV, use multi-tang connectors which are push fitted and pulled out
without the use of tools.
The canister close valve has a stub pipe with 'O' ring seal wh ich is a simple push fit into the canister. A mounting bracket on
the canister close valve enables it to be secured to the underbody via the canister rear mounting bolt.
A hose connects the CCV to the bracket mounted adaptor into which the vent system air filter is screwed.

5. WARNING: B
EFORE PROCEEDING, IT IS ESSENTIAL THAT

THE WARNING NOTES GIVEN IN SECTION 100-00 (UNDER THE
HEADING 'SAFETY PRECAUTIONS') ARE READ AND
UNDERSTOOD.
Disconnect the three valve hoses.
