Post subject: | Relocating the charcoal canister to boot? |
Anyone here give me any reasons why I can't or shouldn't do this? It would be of great convenience to my car build if I can hide it in or under the boot. It wouldn't change how everything is connected up as far as their order goes, just the lengths of the pipes / tubes from where they once were. Since I don't fully understand how often this valve is used or kicks in, could I be looking at having vacuum problems or delays / lags of you will that may cause problems? Thanks. ![]() EDIT: This I got from a rover manual: Evaporative emission canister The evaporative emission (EVAP) canister is situated beneath the LH inner wing valance, and contains charcoal which absorbs and stores fuel from the fuel tank when the engine is not running. When the engine is running the vapour is purged from the canister into the engine and burned. The EVAP canister is purged when the EVAP canister purge valve is opened. Manifold depression draws fresh air into the canister through the charcoal, which releases fuel vapour into the inlet manifold. Evaporative emission canister purge valve The EVAP canister purge valve is operated by the ECM. The valve remains closed until engine temperature rises above 70°C. This is to maintain engine tune and catalyst performance. If the valve was to open with the engine cold or at idling speed, the enriched mixture would delay catalyst light off time and cause erratic idling. When the purge valve opens, fuel vapour from the EVAP canister is drawn along a pipe through the valve and into the inlet manifold for combustion. Blind shot in the dark here but moving it won't do squat, right? ![]() |

Most people relocate them to the bin... They don't do a damn thing performance wise, almost have rarity value now! |

I fitted mine under the wheel arch as per the front cut it came from. Next time it'll just go straight to the bin. It shouldn't matter how long the pipes are though if you want to put it somewhere else on the vehicle. |

I've heard that they are useless after a couple of years. The charcoal stops doing its job apparently. I've also heard that your car wont pass emission tests without it. But being Australia and not California, that shouldn't matter either. |

I would be worried about petrol fumes in the boot. They could build up if you have a petrol overflow from the carby. Then one day you need to jump start the car or hook up a battery charger. One spark and bang. Even just a little petrol vapour makes a pretty big bang and the force of it can only come out the back of the car where you are. Mike |

You have a point there Mike, but the unit does have a breather tube I'd be hanging through the floor if I don't hide the whole thing down there, so I don't think there should be any more fumes in the boot than there normally would be (provided the hoses all correctly seal). I didn't want to put the thing in the wheel arch as its a PITA to get under there and fit the bracket, plus it would make the piping neater under the bonnet. Something to think about. Thanks guys. ![]() |

unless the valve stays in the engine bay, I'd expect that a vacuum pipe running all the way back to the boot would have an adverse effect on performance |

The valve isn't going anywhere, I can't be bothered rewiring the engine harness to extend it. ![]() |
