Although not required, decided to leak check the fuel lines in the fuselage prior to installing flight controls. Figured it will be easier now to correct any leaks than later by having to remove stuff for access. Leak checked as follows: - Capped off the fuel gascolator. - Installed a union and reducer union at the fuel tank fuel line fittings. - Clamped a hose to each fuel line at the fuel tank fuel lines to tie the supply and return lines together. - Fabricated a line to connect to the return line fitting on the firewall and clamped a hose and Schrader valve to the line. - Using a bicycle pump, pressurized the lines to 15 PSI. - Leak checked all fittings using water and soap solution - no leaks detected. - Removed all test lines and fittings.
