    You can try sticking a pencil through the end full line to use as a guide or just loosen the air box with the carburetors attached.

    Give it a try, but in my experience (primarily with the new air box - don't rcall doing this with an old airbox) this is a task where the short cut can take longer than just taking it apart. I didn't have the cross-over line centered well and that throws the other lines out of wack. But I may not be as clever as needed either. :D

    Try sliding a coat hanger, a steel rod or a long scewdriver through the airbox, slide the gas line over the end and then push/pull the wire and fuel line through. (I like the long screwdriver myself!)

    I forgot who showed me that trick but it works for me.

    You can also taper the end of the fuel line on a grinding wheel before you shove it through.

    I have tapered the end of the new hose and used a chopstick to feed it thru. But usually I will just dissasmble as it usually takes me less time than trying to find that chopstick I so carefully placed somewhere that I would not lose it. Usually find the chopstick the next day.

    Disassembly is WAY slower. Taper the end of the hose, shove it through, worst case you have to help at the other end with a small screwdriver or something. We're talking 15 seconds here with MotionPro hose.

    Thanks all!One of the most"fiddly"jobs to me on an airhead is removing the carb tubes,its a pain on my "S" with dellortos.The gas line is dry rotted on my R/T and I need to change it.I'll try one/all(if needed)of the above tricks.

    A bit of welding rod is pretty good.

    Stick it through the old tube, push the new through with the old and the rod so that both tubes guide through.

    When I first got my R100/7... I just ran it behind the airbox on the outside, LoL it was just to fire it up though.

    It's already been said about coat hangers and chopsticks and welding rod.
    The most important one is lubrication. A bit of lube in conjunction with all the other tips will make this a cinch.
    As far as tapering the hose, just cut it at a shallow angle and you shouldn't have any problems.
    Don't cut final length until you get one Tee installed, place it where you want it and match the other side.
