I'm restoring an old Challenger and have replaced the Bennett place diverter pump and installed a new cylinder the problem is it only works in one direction with full force, in reverse it gurgles and spins but only moves slightly and seems to pump air into the lines. I've googled extensively but cannot find a diagram that details exactly how to plumb, wire, and switch for a one cylinder two way actuation, anyone got an answer? It's frustrating because its so simple but no combination of plumbing or wiring has made any difference.

Another thing I had to do also was run a constant batt power to the switch and also have a negative from the batt to the pump itself too
