I noticed that modern gas tanks have baffolding to keep gas from sloshing around when you are driving.

I dont think there's much of any baffolds in the 914 tank so I am wondering would it be wise to keep your fuel tank very full

Seems like when I had one gallon of gas then added about two more for total of three gallons I started to notice a gas odor in my unvented garage in the a.m.

I also noticed that after only ten months my charcoal canister was stinky with gas so I changed the pellets again

I have not even run the car or stares it since I added gas

There is a slosh ring around the inlet, if you take off the top part off of the tank you can see it clearly.
I always try to keep a full tank out of habit, plus it stops internal rusting.

Your canister will get stinky...that's it's job. If you can smell gas with the tank is capped you have a fuel leak or vapour leak somewhere. Carbs can have a gas smell especially after running, regular complaint.

My guess, one of these seals. Easy to check both at same time.

All those have been replaced. Like I said I smell gas odor around the canister , not the expansion tank

Sometimes it's hard to pin down.I do have a new hose kit that covers everything back to the engine compartment if you need it.
Just let me know if that's the direction you want to go.
One last thing. On the seals that are in contact with the gas, we make ours out of Viton, NOT rubber. We found early on that the rubber will not do well with gas or gas fumes and will leak.

How can you tell ours are Viton? we spend the extra money to buy the cinnamon scented Viton. Because it's almost impossible to tell the difference, and we did make some mistakes in the past getting the product mixed up. We've been doing this ( the scented Viton) now for over 4 years. Not saying they are the problem, but you may not be able to rule them out so easily. Where did you buy the seals?

After draining gas, changing fuel line, fuel cap gasket, replace one fuel line , changing charcoal canister pellets and sealing canister: I had no detectable gas odor with just a tiny amount of gas

Today added three gallons and was careful not to splash or spill any and the garage smells like gas again

Was thinking maybe if trying a Freon leak detector because I’m baffled

Have already replaced sensing unit gaskets and expansion tank I have two gaskets was thinking of adding a third gasket under the metal ring

I have not replaced the hard plastic line to the charcoal canister I was told these never leak but who knows

I have already replaced the gas tank with one from AA
Edit: tightened up bolts around evap metal ring I’m afraid I will strip them if they’re any more tighter
