Chapter 21 - Section 6

End Rib and Outlet Piping


End Rib

Since I am using the Feather Lite leading edge, the OD part does not fit well.. Instead, I build a new end rib (more like the R57 and R33) as the end rib. I opened a large hole in the middle such that I can reach through to R57, in case I experience a leak down the road.









Outlet Piping

The outlet piping per plan is quite simple. However, I contemplated fitting a finger strainer in its place as another  of the Cozy builders had done. I really like this configuration because you can back the finger strainer out of the sump for cleaning if necessary. The finger strainer and a matching mounting coupler is readily available from Aircraft Spruce at a reasonable price. I trial fit the finger strainer to my fuel sump and found it to be a bit long. In order for it not to run into the side wall of the sump, I have to raise the finger strainer rather high from the bottom of the sump. To me, that may defeat the purpose of the sump. I prefer my outlet piping no more than an inch from the bottom of the sump. I finally decided to follow the plan's method.


It was a bit challenging to determine the exact fuel line outlet piping location because the plan did not show the extra 2" thick foam along side the forward landing gear bulkhead (note the yellow foam aft the fuel line?). By the time the piping protruded out of the foam and make the 135 degree bend, the piping bend elbow will be way out into the fuselage (passenger sitting area). To avoid that, I moved the outlet piping about 2" forward per plan (7.5" aft of the fuel gauge edge). I also made the bend a bit different such that the fuel line will be closer to the fuselage sides and away from the control rods. I went 90o then 45o as shown. I also projected a straight line (note the line at the tip of the fuel line) from the fuel line exit point sloping down to the seat back and above the wire conduit. 


Once set, I floxed in the fuel line and held it in place with an additional glass strip. I prepared a small layer of BID (with a hole cut out in the middle) and slipped it through the fuel line such that I can cover up the flox afterwards. The small wood block and masking tape were there to hold the pipe in place during cure. Note the fuel sight gauge has been microed and glassed in place as well. 


I followed the Plan's approach in installing the fuel line through the fuselage (as shown).
