Hose connection
First: The cool water from the pump goes thru the Electronic cold water injection (ECWI) solenoid. And continu to the bottom of the exhaust manifold. (The hottest point)
2nd: You have to connect a small hose from the solenoid to the injector on the top of the exhaust manifold.
3nd: Near the manifold you have a 90 fitting on the curved pipe, connect it to the 90 fitting on the engine head.
4th: Connect the top fitting on the pipe near the gaz tank to the bottom fitting at the end of the pipe down in the hull.
5th: Connect the other fitting on the pipe down in the hull near the engine flywheel cover to the outlet fitting (thru hull fitting)
Check for the routing to be sure not pinch, buff or crack the hose when running, install hose clamps. The most important is be sure to always see water from the outlet fitting.
Good luck
