Saltwheels,
Attaching with a nipple shouldn't be a problem as long as there is a bung in the tank for it.
Vibration could be an issue if the nipple is too long.
Ol38y,
1/4" is larger than the factory valve [350cc] and I was considering using two of them.
Thanks for the input, Don
I hope the web elf dosn't nail me for using nipple and bung in the same sentence.
