Okay so can someone give pics of this coupler and maybe a drawing on paint of assembly or something so I know what I’m doing? I’ve never pumped so I don’t really know the general construction of a pump, but I have access to harbor freight for the pump kit, pet smart for this tube that cleans gravel, and any kind of hardware store to get the coupler, I just need to know what I’m looking for and how to put it all together. Thank you very much.
