Over Flow Tank and Charcoal Canister 914-6 Options

[Mike Fitton]

I have researched on this forum for a couple of days trying to figure out if the 914-6 came with an expansion tank and charcoal canister, I do not have either on my '70 # 2604. My 6 has the brackets for the expansion tank so that seems logical but I have seen a lot of posts saying the 6's did not have a canister, does anyone have an original 6 that could comment on this. Thanks!

Great replies guys. Unfortunately when I disassembled my car, I thought it was going to be a quick resto and didn't bother documenting the process. Had I done so I would have pics to support my questions. I kept the parts together as I took the car apart, and the gas tank/filler and expansion tank stayed connected. Didn't occur to me that the attach point on the gas tank for the charcoal canister...didn't necessarily mean that a canister was ever attached. Further confusing was the fact that I have a couple charcoal canisters up on a shelf with 911 parts, but no attachment bracket.

I just helped my son run new plastic and cloth lines on his 72 1.7 from the charcoal canister to the engine compartment, and assumed that I was going to have to do the same...but upon investigation, realized that I am missing the holes in the driver's inner fender. I'm thinking that the gas tanks were the same (with the canister fittings) for both the with and without scenarios...but the inner fenders were different. I see from PET that there were two different expansion tanks, and they look to be "plumbed" differently. I have the one with the notch for the filler neck that has the two small 3mm barbs for the cloth lines. I'll look at the schematics in PET and see what goes where. One question I have is for the 3mm line coming out of the expansion tank, heading to where the canister would have been positioned. Lacking a canister, where does this connect? To the small barb on the plastic Y connected to the larger clear overflow tube that exits out the bottom of the car?
