    Default Metal fuel lines

    Have you used them in your build or considering it? Anybody know the actual weight difference between the supplied lines and metal? Pro's and Con's.

    I built 3 Carbon Cubs would never have used the plastic lines in any of them never weighed them but can't be much of a difference even if it was 5 lbs I would have still used them.

    Replacing plastic fuel lines on a covered cub is zero fun.

    I will use metal lines as well EV but I was hoping others might chime in, builders must all be of the silent type. I understand the weight thing but in the northern climates it just makes sense to me based on past experience. Right Tom?

    I think metal would be a sensible idea. Not a fan of the plastic.

    Glen,
    I have used both with autogas, plastic is like a battery, 4 year life unless you want constant worry. Years ago plastic would get hard, now it gets mushy like bread almost. Auto gas is a moving target. YMMV with 100LL. What are you going to feed your new bird?
    Anyway metal is easy, I'll loan you my rolloflair. Don

    Don,
    I'm strictly a blue gas guy unless in a jam but with the advent of new fuels on the horizon and a cold climate I've decided metal is the best choice for my use and conditions. Not quite ready but gaining.IMG_3567.jpg

    That's exciting Glenn. Looks like Dan's wing benches used an old Trampoline frame?

    I built my EX in 2010 and have not had any problems with the plastic lines. But I have had a few leaks at the fittings. I would not recommend using the superglue suggestion in the manual on the fitting threads. The fitting will explode if you try to loosen or tighten it later if glued like this.

    I should add that I have used a couple hundred gallons of 91 car gas in mine too diluted with 100 LL.
