Need Help!! We received a Mustang 2086 skid steer with the engine removed and all parts in a box. We got the engine installed and installed all three pumps new. We got all the lines to the pump installed except for one piece. It about 12 inches in over all length, 90 degrees and we were told that it neutralizes pressures between pumps. The tractor started fine and ran with no hydraulic oil but as soon as oil was added and restarted, engine stalls. Is it possible for anyone who has a 2086 mustang to send me a picture of there actual pump system? The service reference is no help. Thank you in advance for any help you can provide!!
