I'm seeking advice.
So I played with the gas tank again tonight... The tank looks much better without the evaporation tank and charcoal canister. Is there someone out there running without them? How did you deal with the small hose on the filler neck? I took mine for a drive and got a strong fuel odor after a sharp corner. Fuel sloched in the tank and spilled out of the vent line (now attached to nothing. Is there an alternative or i'm stuck putting back the evaporation tank & charcoal canister? |

The mentioned check valve is there to prevent pulling a vacuum on the tank. A one-way valve so arranged that air can go into the tank, but not out, will prevent fumes from escaping and still allow the tank to be vented. The one thing this doesn't handle is pressurisation caused by heat expanding the fuel in the tank (and raising the pressure of the air above the tank). To handle both cases, plumb the tank vent into catch can vented into the engine's airbox. A charcoal canister is a nice thing to do there, and will be pretty effective at reducing fumes from getting into the air. This canister can be mounted anywhere, and the hoses are there on the 914 to allow it to be mounted in the engine bay easily enough if you want to remove it from above the tank.
