Hi! I'm having trouble finding the original location of the bolts for the charcoal canister mounting bracket on my 1972 olds 350 cutlass. Which brings me to my second question, is this necessary, or should I just route around it? I know it's a primitive emissions control, but is it needed, and if not, how would I go about routing the emissions pipe from the gas tank, and what to do about the front port on the carb where the canister would normally connect? Thank you

Chris, you can plug charcoal canister ports with vacuum caps. Be aware that this can cause your car to smell like fuel though. Especially when turning it off after a drive in the garage. There's really no need to delete a charcoal canister like removing restrictive catalytic converters or HP robbing smog pumps from later cars. It's completely passive. FWIW, I bet the charcoal canister was mounted in front of the passenger's side wheel well (where the battery is on the driver's side).

 

That is the location. It mounts near the sheet metal of the fender. You will find holes there for the support bracket.

 

Thank you. Is it totally on the core support or is one side resting on the plastic wheel well? Thank you

 

Hi Chris

this is a 72 core support i know you used to have a 71 IDK if its different

hope this helps

Chris, here's a shot from the top. There are three mounting points for the clamp. Two bolts go through the plastic wheel well into the core support. One screw comes through the wheel well from the bottom.

 

With regard to car smelling like fuel... my ‘72 Cutlass 350 has recently started smelling of fuel after it’s parked. Stinks up the garage and interior. I do not find any fuel leaks. Does the charcoal canister vacuum line that goes to the carb need to be corrected to a timed vacuum port or manifold vacuum port or does if matter which one? Could the canister be bad, it’s original as far as I know. What else could cause the strong fuel odor in this system? Thanks!
