Hi Everyone,
I have a 4 stroke YS fz63 in my Kyosho Oxalys. I took the cowl off today and found several different fuel lines all gnawed up. There are several different lines criss crossing around my motor(I have a refueling valve installed) so there are also a few places where the lines touch the cowl, motor mount, etc. Through all the vibes they are just getting chewed up by that what they are touching. I want to let the lines hang without binding so it's hard to not have some line touching something somewhere. What about a foam sleeve or something, no metal covered fuel line, that would just make a vibe noise I guess. Any ideas??????? Anyone.
Thanks,
Mike

Take a piece of spare fuel line, split it with an Exacto blade, and put it on the fuel line
where it is rubbing. It will stay in place pretty good, but a small drop of CA would help
keep it in place. If you had some large fuel line to go over the medium line, it might be
even better.

Make sure your prop, spinner, and backplate abe balanced to minimize vibration.

This kind of stuff in the right size is great also for both fuel lines and wires.

Heat shrink tubing.

P51, there are some great suggestions in this thread but as an aside, is the quality of the fuel tubing you are using up to scratch? I've seen a big difference in performance between name brands and really cheap stuff at our field.

I've had a good run with Aerotrend Blueline tubing, FWIW.

Thanks for the good tips. I'd say the tubing I use is of good quality. Got it at my LHS. I think it is Dubro off a spool. It's light blue and pliable. I've had a few others that were simply stiff and almost impossible to get over a fuel nipple.
