First of all, hello I am new here and to vans. I have a 1980 G30 and am trying to figure out what the canister is that is along the frame rail on the drivers side about midway back. It has been raining for 3 days now so I haven’t got a picture of it or been able to trace the hose coming off of it. I am just trying to do some armchair mechanics.

Hey 76 welcome to the site ....dont know of that one but on the passenger side there is a Fuel filter about 3" x 1.5 round dia. A pic would help a lot.



Been thinking it maybe where some one took out the rear heater.... hoses in bypass mode

I will get pics ASAP. It’s dark by the time I get off work. It is about 6” in diameter and about 15” or so long with one hose going towards the engine.

Sounds like the charcoal canister to me as well. Someone might have relocated it at some point.

Is it a hard black plastic, that is what the charcoal canister will look like, with a one or two rubber hoses coming out of it.

The stock evaporation emission canister for '80 would have about 4 ports, be mounted below the front passenger inner fender I believe and look like this:

I could be wrong.

What you have may not be fuel related but it could be a vacuum canister of some type. I don't suppose your G30 is/was originally a diesel by any chance? They had vacuum pumps and vacuum storage canisters different from the gas models.
Without pics we're just guessing....... although I do enjoy the research. smile

We should start a "What the hell is it" sticky.
