grumpy the 7th Posted March 24, 2020 Share Posted March 24, 2020 Whilst I've got the car (K series) on stands doing the serviceDoes anybody know what the charcoal filter actually does? apart from add weight. It's been on the car for the last 20 years without any looking at ?Can it be removed? Does it affect MOT emissions? If it can be removed - how? (there was a link some while back but that post is now blanked)I have a few rubber pipes coming out of the fuel tank, 2 go through under the car each side of the transmission tunnel another goes near the braided fuel hose and one goes somewhere?thanks Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 24, 2020 Member Share Posted March 24, 2020 Have you got Workshop Notice 371 with the required breather modification if you don't have a canister?Jonathan Link to comment Share on other sites More sharing options...
revilla Posted March 24, 2020 Share Posted March 24, 2020 Absorbs fuel vapours from the tank to avoid them venting to the atmosphere, then under suitable running conditions releases them back into the engine inlet system to be burned. Link to comment Share on other sites More sharing options...

Wrightpayne Posted March 24, 2020 Share Posted March 24, 2020 I removed the cannister and fitted a sytec one way fuel valve (about £15) which lets air into the tank (to stop it vacuum imploding) but nothing out.I posted a while ago about fitting it - sytec is quite an unusual / unique word so search engine should find it!

grumpy the 7th Posted March 24, 2020 Author Share Posted March 24, 2020 Johnathan. pm sentWrightpayne. Thanks, which of the pipes did you fit it to? there are two on the filler neck. And did you fit it under the floor or where the canister used to fit in the engine bay/rog Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 24, 2020 Share Posted March 24, 2020 All in the boot - I abandoned the black plastic pipe going to the cannister (in situ) and connected the valve to the filler neck in its place. Sure I did a loop within the filler cover in the boot then dropped it down by the end of the tank.There were posts I read and the workshop notice to follow.Ian Link to comment Share on other sites More sharing options...

grumpy the 7th Posted March 30, 2020 Author Share Posted March 30, 2020 Hi guys again.presume the sytec valve is fitted so petrol can't come out of the pipe but air can get back into the fuel tank. (Question, if some fuel is held back by the valve then if and when the tank needs to draw air in does the fuel held back by the valve leak out?)Also, I presume the pipe from the filter to the fuel rail has to come off. Do I simply block off the fuel rail inlet?Pipes re-wrapped and polished............. Still looking for jobs to docheers Link to comment Share on other sites More sharing options...
