Hi
For hose from thermostat I purchased silicone standard black hose with 30? Degree bend. I then took opportunity to install relief valve to let any air out. You will need to fit a standard SchrAder valve in the aluminium housing I bought from eBay as per below. I did have the thermostat housing modded so the angle was lowered from standard item.

eBay search for : Alloy T Piece Temp Adapter Water Coolant Sensor Silver Temperature Hose Gauge

Why do you need a relief valve next to the expansion tank?
Cheers, Clive.

Hi it’s only for the initial fill to get any air out as it’s the high point in the system with the angle of the hose. Probably a bit belt and braces but seems to work for me.

I use the real steel thermostat housing as Gerry’s recommendation. Yes, the hose does rise slightly on its way to the header tank but the air is bled out via the header tank. With a closed system my header tank is filled right to the brim and overflows to a separate bottle. The air bubbles out into the overflow tank and then sucks spare coolant back in.
Has worked well for 15 years of more.
