Can someone post a picture of the charcoal canister mounted in a GTS (1976-1979 carb, not injected)? Last weekend, I finally got around to replacing all the fuel lines (was smelling gas on a full tank on left turns...not good). As part of that process, I realized that my vehicle is missing the charcoal canister. I'm still not convinced it's all that critical..but I'd like to know where it mounts if I decide to put it into the system. Also, I had a really difficult time from the manuals and parts diagrams sorting out where everything went and why. So I wrote down a quick and dirty set of diagrams specifically around the fuel delivery and vapor system. It's not very pretty, but I've attached the PDF. Please let me know if you find it helpful...if enough folks are interested, I'll make a much nicer version (with part numbers, hose IDs, descriptions, pictures, etc) that won't look like a 5 year old made it.
Directly to the right of the coolant expansion/fill tank. Bolts to rear bulkhead near the top and the RH side of the frame, near the bottom of the canister, IIRC. Kind of pain to get the fasteners in, with the tight quarters, but what isn't in this car. Doug
1976-77 and 1978-79 US 308 use different charcoal canisters and have slightly different fuel evap control systems (although the charcoal canister mounts in the same location as Doug indicated). Here are the figures from the respective OM documents: 1976-77 US 308: Image Unavailable, Please Login 1978-79 US 308: Image Unavailable, Please Login and here's a shot of an actual 1978 US 308 that shows the charcoal canister and the small electric blower that evacuates fuel fumes from the airbox to the charcoal canister at engine shutoff: Image Unavailable, Please Login
@Steve Magnusson and @AZDoug -- thank you and super helpful. Looking in my engine bay, I can see now where both the canister and the 'lectric fan are supposed to go. Now the decision of whether to spend the effort to re-locate the expansion tank (a PO moved it to the right with some through-bolts to luggage area) and purchase & mount the canister + fan + plumbing. Everything is running fine and no more gas smell on the hard corners since I've replaced the fuel lines and run to proper locations. The vapor separator hose outlet is run to below the tank (rather than the canister), so I think the only gain of introducing the canister is to clear out the carb & airbox fumes. And, of course, getting to spend $350-400 and 3-4 hours of time Hmmm...I think this might move lower in the list. Probably spend the time/$$ on the vibrations in the steering above 60mph next.... Thanks again!
I would think the earlier version of the can and lacking the air fan would work that's how mine is obviously.
My '79 car didn't come with the fan (P), I am second owner since 1984, it also has the flapper valve in the entrance to the air cleaner, professionally wired into the open position. The car has euro gauges, but was sold new thru Newport Imports. I am not sure if the emission diffs were from the factory, or the dealership did them. There are couple other oddities, that make me think the car was originally destined for Europe, but diverted to the US. Doug
Do you have the metal flange on the chassis that mounts the fan (P)? If so = it's a US chassis (and those other changes were done later?). If not = it's a "standard" (euro) chassis (or the flange was cut off and repainted).
