My dilemma was how to put two of the RTIC 1 gallon systems on a gold wing when we ride 2 up all the time. Solution was to build a support system. Here is my solution:
(I copied some of the things others did for covering the tubing and sealing the ends. ) Thank you all for different ideas that helped inspire my set up.
The support is a 3/4" conduit bent to fit, with a tab welded on the ends to mount to a crash bar clamp, another support that ties into the fuel cell support, and a bracket that is drilled and tapped into the antenna mounts and the top of the Yeti jug holder. Very solid set up. Done a couple of 600 mile test rides the last couple of weekends. Works very well.
The quick disconnects are 1/8" NFPT double check hydraulic hose fittings (brass with chrome finish) then use 1/8" NFPT brass fuel line 90 degree elbow on top and straight inside. No pipe thread dope used since we are drinking through these. Brass is used in lots of water application, like the fittings for ice makers and water connections in refrigerators.
On the inside of the cap, I put a silicon washer under the stainless steel washer and then screwed in the straight brass fuel line barb connection with 1/4" plastic tubing with stainless steel spring clamp to hole in place.
For venting, I close the top pour cap and then open 1/4 turn, vents just fine. Have not had any issues with ice preventing the hose from reaching the bottom. We just fill about 3/4 with ice and then put the water in. The ice melting to cool the water allows the hose to easily slide into the bottom.
