Fuel pump, Fuel lines, and Brake Lines

I decided a bit ago to reach out to Steve from ASFlightline to get some upgraded hoses for my fuel and brake lines. Could I have just made my own? Sure, but I wanted something a little more sturdy running through the cabin.

When I contacted Steve, AS Flightline did not have a standard EFII kit for the SDS EM-5 system. The did have one for the FlyEFII System 32, so after discussing with Steve, he shipped me that set and I would work with him to develop the changes necessary to support the SDS kit as a drop-in package. I also ordered the brake line hoses for my control approach pedals.

First task was to come up with a mount for the fuel pump assembly from SDS as well as the two filters. I had seen a few people that mounted their pumps with the filters above the pumps in a compact package, and that seemed to be a neat setup. Working with Steve, we developed a mounting setup and some hard-tube that would work with the proposed hose kit.

I shameless followed a similar setup to the EFII system 32 doc on the AS Flightline site to mount my pump in the tunnel. 3/4″ angle aluminum just below the tunnel opening, and fabricating a mounting plate for the pump. The whole pump assembly can be removed via the AirWard side tunnel access panels for servicing. Will verify once all the other “stuff” is installed in the tunnel.

Then I was waiting on my duplex Andair fuel selector. Ordered the FS2020 duplex selector with four 90 degree connectors on the sides of the adapter. The top two adapters point AFT, the bottom two point DOWN. Make sure to install with Locktight 648 per the tag on the box.

I also needed to fabricate a mounting plate for the selector as it doesn’t fit with the VANS supplied kit. Using some spare aluminum sheet, I fabricated a new mounting bracket for the fuel selector and used the edges of the original bracket to mount to the tunnel.

With the fuel pump and fuel selector installed, it’s time to install hoses. Order of install is kinda a real thing as space is tight and sometimes you can’t get a wrench on a fitting with another hose installed. Sorry, didn’t write down my magic ordering – if you are following my lead you can experience this for yourself 🙂

I also had create a few new holes in the fuselage. One in each wing-root for the fuel return line, and one on the firewall for the fuel supply line. I used the measurements in the System32 guide, should work just fine. I also used the TCS 90 degree fuel bushings for the wing root penetration.

I provided my info to Steve so he could post a more complete installation document on his site. End result is that I REALLY like how everything has come together and how things look.

Brake lines were also pretty straight forward. The kits sent by Steve were pretty easy to install. I elected to get the fittings and the hose, so I had everything I needed. It’s pretty obvious where each of the hoses goes once you get into it. For now I just put caps on all of the hose ends and bulkhead fitting to keep everything free of dust / dirt. It will be a while before I’m ready to put fluid into the system.
