A friend of mine once stated that "The meaning of life is having the right tool for the job."  Your point is taken. If all you have is a hack saw, a vice and a crescent wrench (variable spanner) then the field terminate-able Aeroquip may be the best answer for a temporary fix. I say temporary because the rubber hose should be replaced on "time" as the additives in 100LL are the Viarga of rubber hose land.

<< aluminum tubing needs to be properly secured to prevent chafing just like Aeroquip, but if you get chafing on Aeroquip, it's the airframe that will wear, not the hose.>>

The problem here is that the Aeroquip hose IS THE ABRASIVE. If you rub an Aeroquip hose on a smooth surface you will abrade the surface. If you rub an aluminum tube on a smooth surface you polish both.

Buy, borrow or rent the right tool (eBay is a great resource) and secure the tubing with beads of clear silicone so you can enjoy the benefits of weight, cost and longevity.

As for using a swivel fitting on the brake line, ***BAD IDEA***, especially when you consider that there is a hose routing solution to the problem. Swivels leak.
