Hello All, I want to install a flush set up on my 1997 Waverunner 700. I figure there must be a way to "T" into the water lines, but I am not sure what lines to use or tap into. I can't find a diagram showing the water flow thru the engine or where the water enters the block. I found where 2 lines are connected with a plastic "90" fitting that could have just been a solid line, there is no reason to have that 90.... And it looks "factory" to me. Any help would be appreciated.. THX
