The joint between the hoses that go between the thermostat and heater control valve is leaking. I have decided to replace these joined hoses for a single silicone hose. I think there are two at present because slightly different diameters are needed at each end and rubber hoses will leak if the size is not spot on. I swapped out the main hoses a few years ago so do not need a full set. My problem is that I am not sure what it is that I need to order. The Caterham site has items that might be right ones or I can probably get one from Classic Silicone Hoses. Any other supplier suggestions for a bent hose that is not in a kit?
Is the hose I am after the longest one with right angle bend in the Classic Silicone Hoses kit?:
Could it be this one:
Or this one:
Something that I have come across in an old thread suggests that there was some confusion in some old manuals as to which hoses went top and bottom at the valve. In my case the thermostat goes to the top and the bottom hose goes to the rail which is the opposite to post #11 in the old thread. I have few problems with airlocks so I am wondering if the confusion could be part of the reason why some people have a nightmare getting rid of airlocks and others do not. Mine is a per Section 9 page 11 of the build manual.
