Afternoon does anyone know where i can get an aluminium header tank with two top outlets as i need to go to the overflow of the radiator and to the small pipe on the engine thermostat. Or is there another way of doing it can the two be connected and then back to the headertank hope that lot makes sense.

Similar to what I have and I just tee'd the two together so only needed one inlet, just make sure they both rise to the header tank so you clear any air. HTH Ray

Iv managed to find one on car builder solutions with two 8mm top one bottom
