fuel line - severe abrasion

[RONSIM]

chewed through by lower baffle fastening tie-rod. Oil leaking. Obviously making a mess. Checked other side and had to make adjustments.

Engine had 350hrs since new.

It does indeed. Or maybe rubbing against another steel braided line, or maybe a Bowden cable.

It works the other way too. Poke around in enough airplanes and you'll find one where the steel braided line ate into a motor mount tube.

Baffle tie rods are from the "We always done 'er that way" bin. The odd thing is that they tie together wraps on two cylinders vibrating independently. It's a small mod to tie the front and rear wraps to the center baffle plate rather than to each other, and it sidesteps drain tube issues.
