Brief Description: Fuel lines; left brake line
|
|
There are a couple of projects I hadn't particularly looked forward to during the building of the airplane. Looking back on them, none of them now seems particularly menacing. I guess it will be the same with the two fuel lines I fabricated today. (These are the supply and return lines that run between the fuel selector and the electric fuel boost pump package.) These are very tricky installations, with tight quarters and very tight bends. I had originally decided I would simply avoid any potential problems by using Aeroquip flexible hose with angled racecar fittings on them. But as I began doing that today, I was struck with a strong desire to BEAT this issue and, by God, bend them out of raw 3/8" aluminum tubing -- just the way Dick VanGrunsven deigned. So I did.
It took three attempts for one of them, and two for the other, but they are now installed and looking good, if I do say so myself. (Anybody need some scrapped aluminum fuel lines? I guess they'll go on my Builder Wall of Shame.)
The only remaining job is to attach a right-angle fitting to the main fuel feed line from the bottom of the fuel selector. I'll try to find one tomorrow. If I can, the entire fuel system aft of the firewall should be complete later in the week.
Installing these two fuel lines paved the way for at least a dozen other jobs -- including installing the left brake line, which I also did today. I just need to seal it with Fuel Lube.
