Posts #17 and #18 show a '75 and '76 and the cannister is mounted differently in each (ie. turned 180 degrees). Not sure which is "stock/original" from the factory or if the different years turned it 180 degrees. On my early 74 2.0L, my cannister is up front.

Then it's an early '74 with that setup.

Hey Kevin,
They moved the canister from the front trunk to the engine compartment sometime after the 11/73 builds. In later 74's it was located as shown in the first 2 pictures below. In 75-76 years (3rd picture), it was moved again to the battery tray.
This is the same setup for 1.8's and 2.0's
If you are looking for routing of hoses and hose sizes, look on Jeff Bowlsby's site. He has just about everything you will need there. Here is the link: https://bowlsby.net/914/Classic/TechNotebook.htm
If you need the bracket, check with Bruce Stone.
Hope this helps.
Greg

Yep, my '74 (build date: 8/73) has it the same. Some PO screwed up the hoses and the canister filled with fuel and gave off a nasty odor. Dumped it, replaced the charcoal, and painted the canister a couple years ago and had the hoses setup closer to the way they should be (I have carbs).

So to install in the engine compartment, one needs to only run a long line from the expansion tank to the engine compartment?

Correct.

Yes, the thin plastic line runs down the center tunnel next to the fuel lines. It enters the tunnel below the fuel tank through the grommet for the fuel lines and comes out of the lower rear fire wall below the main wiring loom (to the left of the left most fuel line). It has it's own hole and grommet. I think it follows the fuel lines and comes into the engine compartment somewhere close to the battery tray base.
Of course, if you have an early car, there won't be a third hole in the grommet for the fuel lines under the gas tank or a hole in the lower rear firewall. You will need to improvise here. You can find a later grommet for the fuel lines that has the hole in it and drill a hole in the lower firewall and add the grommet there.
You will have to find the thin hose that runs front to back used because it's NLA from Porsche.

jeff's site was very helpful. found a canister and mounting strap. located the small line that runs from the fuel tank to the canister. its rather long and was found on the rear area of the engine which leads me to think the canister was not battery tray mounted. is the strap mount type specific for the locations or the same for both? i have a box of ljet stuff and the strap mount may be in there. i'm not sure what the correct one looks like and exactly how/where it bolts on. could use a picture of the correct rear strap and one of how it's installed. getting closer….

Where you able to find a new cannister or did you just find one in good shape?
I've been thinking of taking my early 1974 cannister out and replenishing with charcoal but not sure if it can even be taken apart. Made of plastic I believe.

the green car in greg's post, #7, shows the rear placement. jim hoyland advised me there is a mounting point(s) on the body, in the engine compartment, for the canister strap. when replacing the charcoal, is filtration product like that used in a fish tank? if not, where to source?

This has been helpful to me. Thanks everyone. Apparently the canister was removed somewhere along the way in my '76, but I did find the line from the tank. Thin brittle plastic. I was very puzzled, not realizing that the whole canister was gone. I had thought it was lurking somewhere in front.

Yes, activated charcoal like used in fish tanks. Your local pet/aquarium store will have the activated charcoal pellets. That's myplan on replacing/refilling my cannister....but getting it open without destroying it is the key?

the plastic style canister looks like it comes apart.
found the stud for the strap. the car has been converted to carbs. the air filter for the pass side carb will be in the way using the rear mounting provision. i don't want to drill an extra hole to shift the canister over. i'm thinking of possibly going to the battery tray location.

I just replaced the activated charcoal in my 1974 canister. The top pops off with a screwdriver and some gentle prying. Easy job by 914 standards. You will need 1.7 lbs of activated charcoal. No more gas fumes in the cabin!

did you buy the charcoal at a pet supply store?
Posted by: jim_hoyland Jan 11 2014, 08:09 AM
I have used the aquarium charcoal; some say that gently heating the charcoal from the canister in an oven for 6 hours will rejuvenate the charcoals capacity
Posted by: rhodyguy Jan 11 2014, 08:12 AM
haha. 6 hours + of stench in the kitchen. i'd be sleeping there. thanks jim.

I bought it from an ebay vendor.
