Inquiry (采购产品): pump diagram I have a 13-261p Butler pump #200061126004 and the valves will not allow the return flow to the resevoir. The Actuator works fine if I remove the return side and vent to the tank. Could you please send me a flow diagram or something that would help me? **** Hidden Message ***** Fred Snyder 76550 Company: F and F tire E-mail: babyuav@earthlink.net **** Hidden Message ***** babyuav@earthlink.net
