FX-1 Duel cooling advice needed

Hello, i am about to fit duel cooling to my Fx1 with a 760 motor, twin carbs, 144 pump, b pipe and after market waterbox.
I have tapped into the jet pump, using the factory syphon tubing, but need advice on to where tap the other end to the exhaust,
Also I am installing a flow control valve and need advice on where to fit it.
Please have a look at the photos provided.726DEF1C-BB7B-4478-96DB-0406626F0403.jpeg
Any photos of where you guys fitted yours would be really helpful, thanks....0A1881ED-B6D9-4A02-AEE5-4DA739132B24.jpegC0C1A3F8-A4DB-48E7-8274-2FC8978758A6.jpegCEAD19ED-2FCC-4AB6-B3DA-95FD33A168F8.jpeg

No Square..No Round..FX-1
You can cheat by removing the pressed in plug on the end of the pump boss, where the factory presses in the straight SS adapter for cooling. Drill to size then use a insert X male elbow to feed the new line. That plug, (looks like a mini freeze out plug) will eventually blow out anyway and you will loose all cooling. While your doing this, you should change out the original aluminum cooling line (with STAINLESS STEEL) because it's probably all corroded (or waiting to be) with pinholes. That happens to make sure your foam gets waterlogged. It's a Vicious cycle. Welcome to the tip of the iceberg....
And like codybrown mentioned, what pipe are you running?

I’d suggest tapping your manifold for dual cooling, but leaving your pump alone. A single cooling line from the pump will be sufficient unless you are running a big motor. That way you don’t take up both thru-hull tubes and can still use the stock siphon bilge which is very effective.
