It absorbs fuel vapor from the tank, then routes them into the air cleaner to be burned rather than vented into the atmosphere... If you have a visual emissions equipment inspection your car could fail without it... As far as operation, their will be no difference with or without it...
That is the carbon canister which acts as a air purifier for fumes from the fuel tank. If you don't mind your underhood area filling with active fuel vapors you can remove it.
Ok thanks for the information !and where a plug the hose if I have an air cleaner Hi-po style ? thanks
Do you have emission testing in Quebec? Here in Ontario, we don't on older cars, but we can be pulled into inspection, and if we don't have it, we get a fine. They have been know to set up mobile inspection stations , outside car shows and cruise nights...
We've been told, if it came with it from the factory, it has to be in place on the car...regardless of the year.
Not sure what you mean by Hi-po style. Aftermarket? Many aftermarket air cleaners have knock outs for those connections.
If yours is in that good of shape, I would certainly keep it! I can't even find the hose for mine! (at least for a reasonable price) This idea may be wrong, but in theory the canister collects fumes from the fuel tank and stores them in a charcoal media to be burned once the engine is running. So in doing this wouldn't the fuel mileage be better? You would be using otherwise wasted fuel vapors.
This is one of my giant pet peeves…. I won’t get into the emissions part of it but I will say this is flat out harassment. Targeting people outside of car shows is not equality under the law, randomly testing on any given day or as part of registration is one thing (I don’t agree that either) but to actively target groups of people is despicable. We have a similarity in southern California, they come after law abiding citizens but turn a blind eye toward every vehicle coming up from Mexico with their crap gasoline. It’s absurd…
I'd make a hole in the bottom of the air cleaner, inside the filter, stick the hose up into the air cleaner and secure it somehow. Maybe a hose clamp to stop it from falling back out.
You could use a crankcase breather filter through your hole. It would be held on by a clip and have a protruding barb to put the hose on. It is found on a lot of Ford vehicles.
One of the two smaller round holes in your canister is for the vapor connection. The other is for the crank case ventilation. You just need to buy the correct adapter for it. Most likely the one nearest to the large snout opening.
