YUP!! #27!!! That be da part I'm havin' da problem with...
Does the part that looks like a hex head bolt on that coupling do anything to relieve pressure in the lines? Or, is it just something to bleed air out of the lines? If it does function as a relief valve, how does it work? Has anyone ever taken one apart to discover how it could bleed off hydraulic pressure in both the send and return lines?
Help is appreciated!!
