Re: Peanut tank with a friction drive
You should easily be able to find another cap. Lowes and Home depot have small motor replacement caps, as do most small engine repair shops. The nipple should be the same size as the outlet on the peanut tank where the line comes off the shutoff valve. I'd put a filter under the tank as well. The hole in the gas cap should be enlarged and the nipple glued in with an epoxy based glue. You need the fuel shut off when you refuel. However, the system won't work if the fuel valve is closed when running. The vent for the system becomes the peanut tank cap.
It'll probably be a good idea to always shut off the valve on the peanut tank each time you stop running the engine, to prevent the possibility of flooding as the tank will be higher than the carb.
