I know you can get them from demon tweeks but its a sort of pick-a-mix affair. You buy your hoses and then your fittings, but i don't know what diameter hoses to get and what fittings i need and i don't want to pull the old lines off to be waiting for the correct fittings. In all honesty i thought you'd be able to buy a set of four off the shelf at somewhere like bigboys toys, obviously i'm wrong.
