@redfish I hadnt thought of doing a compression union I think I'll try that at the hole. its really small but it sure hell sprayed everywhere :( about what size union? I have a flare tool to do the lines
You don't flare the line ends for a compression union, just clean straight ends.
Just cut it (pref with a tubing cutter) right where the hole is and assemble the compression union on the lines.
They use a collar that the nut compresses, so you have to assemble them in this order, nut on the line, then the collar, then put the tube allthe way in the fitting and run the nut down snug.
Do the exact same for the other end.
Whatever size your lines are is what size fitting you need. (3/8 tube takes a 3/8 compression union)
