It is tight there; watch them bend radii. I presume this is 3/8"
tubing? Factory is c. 5/16" ID.
I'm forgetting now what's wrong with the rubber hose. The Rotax is to
be run on mogas, and so like auto fuel system failures are quite
common but just we don't hear about them? I bought a load of 5/16"
auto hose to swap, as the supplied external braid is not conducive to
inspection and seems to hug hose barbs tenaciously.
I admit aluminum line sounds better to me too, but in the event of an
accident the line can fracture more easily, unless run to prevent that
(how?).
