Just a thought. You might want to consider getting one or two rolls of medium sized Prather pink tubing. IIRC, it's less expensive that way and you're not limited to the roughly one meter length. I bought a roll of large for my boat(thing is an 11cc nitro guzzler from Hades) after finding out that medium was too small(thing was running extremely lean, so much so it pitted the head and piston), something that taught me the importance of using the correct size tubing. As Speed said, it will stay on the fuel tubes and fittings fine, never have needed any sort of ties or clamps to keep the lines on the tubes.
