I know there are lots of topics on this but none really say what to do.

Hi i have a charcoal cannister, can i remove this? Its ugly and prob dont do much.

I have a stainless exhaust, no cat and a hif38.

Will it pass the MOT without?

Do i block the hose fittings off that go to the carb, fuel tank etc.


Also i have a heated inlet manifold. Is it worth putting water through it?

If so which part of the cooling system is best to take off.

Cheers Steve

Any help?

The charcoal canister is nothing to do with the exhaust or the engine emissions control system. It's part of the fuel evaporative loss system. You cannot technically legally remove it but there is no testing done to the car that requires it to be there. It forms the fuel tank vent and the float chamber vent. These will need conventional vents if the system is removed. The purge line to the carb will have to be blocked and the vacuum lines redirected to keep the vacuum advance working. There is no point getting rid of it though and it does somewhat reduce your fuel losses which right now are expensive.

Plumb in the manifold, people will tell you not to or to isolate it in the summer. It's best being plumbed in. Tee it off the heater so it runs all the time wherever the heater control is set. You might want to block any other thermostat bypass that's in place and use the manifold as the bypass.

hi, joining in; we at the same point. the pipe from canister runs to the carb does it? (its all disconnected when we got car) and the manifold plumbing when going from standard set up; is to be done afresh is it? theres nothing we can use or adapt?
thanks
