I need some help here.

I have an 18 ft round intex pool, ive got the water flow controls on both ports (im know im not using correct lingo here). I want to keep these intact because it works well and would like to adapt from it. My hoses dont fit onto the Hayward pump and filter. Im useing hoses that have threads at both ends the hayward pump and filter are straight. I found one hose laying around here that I was able to clamp in place and fit inside one of my hoses. Problem I dont know how to buy another one of these... But I am sure there is some kit I can use to do this properly.

Hope this makes sense... Please help me.
