Lowering carbon canister

The hose coming from the top of the carbon canister was touching the bonnet so I did a couple of mods.
- lowered the carbon canister slightly. The canister wasn't down as far as the tab that is meant to stop it from going any further. By filing away a bit of the plastic on the flanges I got it fully down
- after rummaging through the MX-5 bits i found the original top hose connector which had a handy couple of 90deg angles. It meant the hose didn't protrude as far up. I'll have to join it to the hose that goes to the vent on the fuel tank.
