Charcoal canister

[BaaderMeinhofWagen]

Is this thing beyond it's useful life?

Should I just delete it?

What about the hose that connects it to the Carb?

Thanks

This collects the fumes from the vapor tank in your trunk (under the right parcel shelf).

If you delete the charcoal canister, your need to vent the vapor tank AND fuel tank to somewhere ... where you won't get gas fumes in or around the car, especially if you park in a garage!

The hose from the charcoal canister to the intake manifold (below the carb) is the secondary crankcase ventilation port that sucks the fuel tank vent air and the valve cover vent (crankcase primary vent) and distributed this equally to each of the 4 intake runners.

If you toss this canister onto your neighbor's ice rink, then be sure to plug that manifold nipple below the carb.

There's a thread in the archives about changing the charcoal in the canister.

So for normal ops should the middle nipple of the canister which appears to be capped off by a white cap be plumbed to the vapour tank?

No, the outer nipple on the canister is the one to cap (if not connected to the intake).

The middle nip is the one from the vapor tank and fuel tank.

Ok. I do recall that the blue tube from the vapour tank was dangling loose on the side of the engine bay for some reason. I'll reconnect as per the diagram.

Maybe that will help with the fumes.

Mine went bye-bye many years ago.  However, if you do this, you'll need to plug the place where the vent hose enters the carburetor, then plug the nipple on the gas tank where the other end of the vent line is attached to the tank.   That has to be plugged or it'll tend to siphon gas out of the tank.

Sorry for the late he delayed response. What kind of a plug do I need to plug the vapour port at the carb?

The vent at the tank is on the rubber boot on the fill pipe to fender, not the tank.  It is above the liquid level in the tank and has no dip tube and so it will not siphon.

However, the tank needs a vent and there is a pre formed vent tube available new and the rubber end that routes the vented vapors to the ground.  The blank plug is located to the left of center to the rear of the spare tire.
