Brief Description:  Install Air-Oil Separator and Fine Fuel Filter

Installed the Air-Oil Separator by attaching it to the upper-right engine mount arm with 2 adel clamps. The 2 x AN4 bolts are extra long (AN4-16) through 2 x aluminum spacres to separate the Air-Oil Separator from the regulator/rectifier. After attaching everything together, I torqued down the nuts and hit them with torque seal.

The fine fuel filter took a little more work, but only because I hade to fabricate a couple of aluminum straps to wrap around the filter. I had luckily saved a long strip of aluminum from when I cut it off my aileron skin to install a hinge. Although wider than that shown in the assembly pictures, I deemed it close enough for my purposes.

In short, the two aluminum straps wrap snugly around the filter. At each of their ends, you make a hole for an AN3 bolt which is pushed through an adel clamp attached to the upper left engine mount arm. Fittings are attached to each end of the filter. The aft fitting will be connected, via braided hose, to the dual fuel pump assembly. The forward fitting will be connected, via braided hose, to the engine fuel injector. Lastly, I added the fuel pressure sensor to the forward fitting. Once in place, I torqed everything down and added some torque seal.
