More fuel system progress

10 Feb 2006 More fuel system progress

I received some more AN fittings in the mail today from Aircraft Spruce. I’ve probably spent several hundred dollars on these fittings – but I think I finally have all that I will need for the project. Wow.
I installed the “manifold” for the fuel pressure sensor, and I connected the fuel system to the engine.

Here are some pictures of the manifold that I used to connect the fuel pressure sensor, the rubber fuel hose, and the aluminum tubing to get the fuel line through the firewall:

Closeup of the fuel pressure sensor. I still need to “wire” it. One advantage of this method, using the manifold, is that it is grounded.

View from the top. You can also see the fuel return line which I have yet to hook up. I’ll do that once the other firewall penetrations are complete, since I have a lot of flexibility with the fuel lines.

Here is the connection between the firewall and the engine. Note that I have to go from the aluminum firewall penetration back to the rubber hose.

Note the “adel” cushion clamps used to stabilize the connections.

Here is the type of connector I used to mate the rubber hose to the aluminum fitting. The connector is steel, so I also added a Del aluminum gasket between the steel fitting and the aluminum tube.
