First step is to cut off the bulge on the ends of the supply and return lines coming out the top of the center. First picture, the left line is the 5/16” diameter return line, center line is the 1/4” diameter vent tube, and the right line is the 3/8” diameter supply line.

Second picture is after I cut off the bulge on the ends. Once the ends are cut off, de-bur the ends and the ID of each line and flush the lines with brake cleaner to remove all the metal shavings.
