Ed Sikora asked:  " contempleated putting a tubing loop from inlet to
outlet "

Ed, The lubing is probably a good idea but a tube from inlet to outlet
won't work because the volume of fluid is greater on the side of the
cylinder without the shaft because of the space taken up by the shaft
inside the cylinder. You will need some kind of system to absorb the
extra fluid. You should be able to come up with some kind of an open
system to do this. A simple tube from inlet to outlet will set up a
hydraulic lock that will prevent the cylinder from moving (or more
likely, will burst the tubing if you're using poly). Like you, I didn't
hook up my hydraulics for several years after kit delivery but when I
did, there was no problem with leakage, everything worked fine. Use Dell
seals on all of the flared fittings.
