Strong fuel smell after a drive in the heat of summer.

Hello Gents, Ladies....

What solutions are there for keeping the odors down from the fuel return and vent lines. I am not using them because I have eliminated the canister and the pump only has one line running to it. Rubber plugs dont seem to last very long. any ideas?

Thanks!
Bill

the tube in the carb is just pressed in so you can remove that and put a plug in its place.

Now you know what the canister does... Why not install one and hide it in an inconspicuous place? As for the pump, if it has two hose fittings, then it was designed to feed fuel to the carb up to a certain pressure, and return the rest to the gas tank. Not using the return line gives the excess fuel no place to go but the carb and it will slowly flood. You might try using a single fitting pump with a built in regulator, but the whole idea was to have cool fuel sent to the carb instead of hot fuel waiting by the hot motor, ready to vapor-lock. If your return line and vapor line are open to atmosphere, then you have provided an open vapor vent for gasoline fumes, that were supposed to be collected by the canister.
