Brief Description:  Installation of the Copper Fuel Line and Drain

Preparing the drain line: Cleaned the end of a 1/2 inch copper pipe, applied solder paste and test fitted a 1/4 inch pipe male adapter. The fitting was good. Lit a propane torch and heated the fitting until the solder flowed. Removed the heat and checked to ensure complete flow of solder around the fitting. Mounted the copper pipe to the fuel tank at the bottom fitting. Measured across the bottom of the fuselage and marked the drain pipe at the bottom. Removed the drain pipe and measured back from the mark to allow for the female 1/4 inch pipe fitting to end near the bottom of the fuselage. Marked this position and cut the pipe at this mark. Again cleaned the end of the pipe and applied solder paste. Test fitted the female pipe end. Mounted the drain pipe to the fuel tank to test the length to ensure correct position. It checked out so completed the soldering of the female fitting. This completes the fuel tank drain to be installed later.

The original plan for the fuel line was to go from the value straight out and then turn 90 deg and connect to the gascolator. With the electric fuses mounted on the firewall not enough room was available for this to work. Acquired a 1/4 inch pipe 90 deg fitting which was installed on the end of the main fuel value. Added the 1/4 inch pipe to 5/16 compression adapter to the 90 deg fitting which allowed the copper fuel line to be installed at the fuel tank. Re-bent the copper fuel line to accommodate its new position. Shorten the fuel line by about 1/2 inch to fit it into the gascolator. Tighten both end of the fuel line.
