Hi there Rich
We cut down the original Renesis manifold with the exiting water going =
straight out with a screw on filler cap above.
We had to do this as the engine is pretty close to the cowl top in the =
Glasair.
As far as a header tank above. Our rad is to the side and a little lower =
than the in/out manifold so its always going to be lifting the water a =
few inches.
Do you mean to provide some room to collect any air above the inlet?

Cheers

Steve
