Expansion tank set up
zx12-r cooling system set up
Nearly there with the build and thought it be an idea to fit an expansion tank and was hopeing someone could assist me in fitting it.
I have drawn a diagram below to hopefully help show how i think i should do it.
My car has a ZX12-R engine with a Electric water pump , polo radiator, alloy header tank with a Stant high pressure rad cap.
I was planning on just running my overflow pressure release pipe from my header tank to the expansion tank, is this correct ?

What you need is a T in your bottom hose that goes to the bottom of the header tank and the small hose that you show should be to the top of the
header tank.
No expansion tank required.
You have connected the entire header to the same side of the water pump so you will not get any flow through it.
Make sure that the header tank is the highest part of the system too!
Where is the engine in your diagram?

You might not need to run the expansion tank at all. I have a similar setup and just have the header tank (running half full) connected to the feed
side of the EWP, giving it a constant head of water. 6k miles later I haven't had any cooling problems.
*edit*
Have you got any form of temp control for the pump? It will be going flat out all the time - why not ditch the engine thermostat and install the
Davies Craig jobbie - it will give the EWP an easier life and release a few more horses too.

I hate drawing diagrams and thought it be easier to just draw the engine thermostat which is situated on the engine probably confused things though as
i have actuallt taken out the mechanical thermostat and replaced it with the Davis Craig adjustable thermostat.
Everyone keeps saying no expansion tank required and yet i remember reading on here somewhere that an expansion is a must for a track car.
