Aight I have a pair of Showtime Pumps. I am new to hydraulics so i have a couple of questions about my pumps. First off one has a leak and i know i must get a repair our replace it. this brings me to my first question is it possible to have it repaired? If so it would be nice to be pointed in the direction of a fix. Next i need to know about finding the sizes of the pump heads. i know that there are diffrent sizes for diffrent pumps. if i am going to need a new pump were do i need to look to know what sizes will fit my hoses. Third if replacing a pump what are some importent pointers that i could be given in mounting, and instaling my new pump. Thanx for your help on any  topic mentioned....
