Does anyone know the easiest way to bypass a charcoal canister on a 73 Duster. It is a slant six and I think I just want to get it off and bypass the hoses.

Just remove it. You can let the hose vent as you wish. I did that on a 77 Volare

cap the nipple w one of those 5 cent colored vacuum caps to keep dirt out. Not as critical as the same dia hole in an air cleaner housing for instance as it is not pulling vacuum but I still would.

I bypassed those things before I even knew what they did.

I ran mine for years with the cannister gone but the lines not plugged. I think the lines were either rusted or bent shut years ago so it made no difference.

You can plug it, but that charcoal canister is the vent for your gas tank, so you need to vent it some other way. I removed the charcoal canister on my 74 Cuda and plugged it. For the next month or so, every time I removed the gas cap I could hear a large rush of air going into the filler tube, and I could also hear the metal gas tank flexing at the same time. What was happening is when I filled the gas tank, there is just a little air in the top of the tank. As you drive the car and empty the tank, there is no vent to equalize the pressure, and you are creating a vacuum in the tank. Then when you pull off the gas cap, air rushes in the tank to equalize the pressure. The thing that worried me about this was the flexing of the tank due to the vacuum, and then the releasing of the vacuum causing it to flex back to its original shape - I was worried that this might eventually cause a leak in the tank. My solution was to buy a vented gas cap - no more problem. You could also leave the charcoal canister line open (unplugged), or make a little filter to fit on the end of the line if you're worried about crud getting into the line.

It's also there to prevent a fuel leak in the engine compartment in the event of a roll-over.

Can someone please explain to me why a person would want to defeat the canister? What's the advantage?
