Cannister Hoses
There are three hose nipples , two big and one little .
The little one goes to a carby nipple that gets vacuum when you're off idle so it doesn't open the purge valve during hot idle & flood the engine .
One big hose goes to the tank and may have a 'T' moulded near it , the other goes to the engine , dang if I've forgotten this basic stuff and I'm one of the very few who bothers to re connect these simple devices .
Remember : f you use this cannister , the gas cap must not be vented .
