I have mine mounted in front of the battery where the CD box normally mounts. This way you only have to run one hose to the engine compartment. I am using one of the later plastic ones that is easy to refill.

I can take some pictures later today. I ran the single hose down the passenger side rocker panel. Works great, no more gas fumes. 75/76 914’s had the canister in the engine compartment. They ran a really small hose down the tunnel with the fuel lines. The canister either mounted next to the battery or in front of the trunk.

Hard to see, but the late model plastic charcoal canister, fits perfectly between the battery and the firewall. I attached the bracket where the 914-6 CD mounts to, which is not needed with a 3.2

With the canister in the engine compartment, you only need one hose to the expansion chamber on the gas tank.

In the originality forum, you can see the stock locations in the engine compartment.

If running a carb setup is there a proper way route the charcoal/PCV set up. Had a tough time searching for this topic.

Most carb air cleaners have a fitting for the canister. If they don’t make one.

I have a 911 engine with carbs. The filter return line is connected to the air cleaner - per the diagram Steve added above. No gas smell in the garage.

Sounds like you might need an external expansion chamber. 911’s used an external expansion chamber, but they are kind of bulky.

(IMG:style_emoticons/default/agree.gif) You have to have an expansion chamber and a charcoal canister.

Weber rain hats you'll have to drill a hole on the top, add a grommet and a 90 degree fitting.

Ben I don't really think you can remove the engine bay smell due to the nature off carbs I noticed more smell when I used the twin K&N setup ,I'am now back to using the stock air cleaner and it seems less.
Any system will only be effective when you have suction and pressure when the engine is running ,perhaps I'am wrong but that's my take on it.

You are correct, but there are also gas fumes that come from the gas tank vent. If this breather/vent is not connected to an evaporative system, you will also get gas fumes in the cabin and the garage. Even driving my car to the store, if the windows were rolled up, I still had gas fumes in the car. I have heard of people taking the tank breather and running it through a fuel filter and then out the bottom of the car. I tried all the tricks and my cabin still smelt like gas as well as the inside of the garage. After installing the expansion chamber and charcoal canister the fumes in the cabin and in the garage went away..

It's funny I've been too lazy to finish mounting my charcoal canister.
All I have is the expansion tank and the small plastic hose, plugged (IIRC) and I never smell gas.

I bought a plastic charcoal canister that I can replenish to replace my 73 metal canister and I have a couple of questions:
1. What is the direction of flow on the plastic canister? Flow from the fan to the air cleaner towards the plastic removable cap?
2. How do you know if the charcoal pellets need to be replenished? I opened it up and the it was full of pellets that look normal.

Thanks-Rick

This is the plastic canister I bought and hopefully I can use the existing mounting bracket on my 73.

I doubt it... I thought the 73 had a metal container which is more flatter.
This plastic one is the one I have mounted between the battery and the firewall.
