This blog was created to memorialize the building process of my Van's Aircraft RV-14 and to satisfy the requirements for certification in the Experimental Amateur Built Aircraft category. It will also serve as a central location for ME to reference in the future on processes and techniques I used during the build. Additionally, it will allow my family, friends, and other interested builders the opportunity to follow along during my build…..and might be helpful to someone along the way.
In March of 2020, I purchased and installed the Cabin Fuel Line Package (also known as the Complete Firewall Aft Hose Kit) from Aircraft Specialty. The installation of this hose kit was completed in:
Fuselage, Section 31-Fuel System, Part 4 - 6 (also included below)
Tonight, was the last work session for the Section 31: Fuel System.
I let the proseal from Part 5 dry overnight and installed the last fuel line hose from the Electric Fuel Pump to the Firewall as shown below. This hose was also part of the RV-14 Cabin Fuel Line package I purchased from Aircraft Specialty.
Tonight’s portion of the work session focusing on the Fuel System went relatively quickly.
I have been putting off this step because I didn’t have any proseal. Well, guess what?.....I got some proseal. In the center of the picture below, you can see the AN833-6D Elbow Fitting (it has a black cap on it) inserted through the Firewall. Then, you have the blue AN924-6D nut and the green AN SPACER 6D. To complete the installed proseal had to be installed between the AN SPACER and the Firewall.
To do this, I put the center hole of the AN SPACER around my finger and applied the proseal on the side of the AN SPACER that will rest against the Firewall (after sanding off the primer that is). Next, I installed the Elbow fitting through the hole in the Firewall, slid on the AN SPACER, smashed it against the Firewall, and installed the blue nut. As the nut was tightened, the proseal oozed out around the AN SPACER.....the proseal Gods were smiling down on me with this one and the proseal looks pretty damn good!
As I mentioned in the Part 1, I ordered the RV-14 Cabin Fuel Line Kit from Aircraft Specialty. I’m not sure how much time this saved, but I bet it was significant. Below are the four fuel lines that get installed inside the cabin. They came from Aircraft Specialty just like you see them.....plastic red plugs installed in each end and the lines were complete and ready to install.
The plans excerpt below shows the installation of the left fuel line that runs under the pilot. (The right side under the passenger seat is installed the same way).
Here is the fuel line installed, as shown in the plans excerpt above, on the left side of the plane.
This is where the fuel line penetrates the Fuselage on the left side of the plane.....the AN833-6D Elbow and the AN924-6D Nut are installed here. I put orange torque seal on the nut and installed the rubber cap on the end of the elbow. This will prevent any debris from getting in the fuel line.
This is the right side of the airplane. (In the circle below, I have one screw/nut that needs to be installed in the upper part of the Fuel Line Bracket. When I initially installed the screw/nut, the screw broke in half while it was being tightened. Not sure if it was my fault or a busted screw. Either way, I ordered a few extra screws and it will install it when it arrives).
This is the fuel line penetration on the right side of the Fuselage.....applied torque seal and rubber cap on this side also.
The left and right side fuel lines connect to the aft side of the Fuel Selector as shown below.
This is the fuel line that connects the forward side of the Fuel Selector and Fuel Filter. Both connections have orange torque seal applied.
I will install the final fuel line (from the Boost Pump to the Firewall) at a later date. There is an aluminum spacer that needs to be prepared which gets installed with the blue elbow through the Firewall. I haven’t prepared that spacer yet.....soon!
