Brief Description: Continue fuel lines
|
|
Damn fuel lines. I fumbled around accomplishing nothing really for the line along the spar and then put together this list of my options at this point. The second is the Vans plans, though to be sure, the plans are vague about alignment of the lines through the weldment. Frankly their design and description of fuel lines for the nose-gear models sucks.
