Thanks for all of your help. The red tube that is on my receiver tray is the outter tubing from a sullivan nyrod. I originally had it all the way to the end, but ended up cutting it back so that it wouldn't cover the ends. Where it is going to be in the plane; I shouldn't have any problems with it being bumped or moved around.

Is that a gas plane in your pic? If so, what fuel tubing are you using?

Thanks again
