I need a 50mm piece of 10mm water hose. I'm lothed to buy a 1m length for this piece unless I really have to. I do have some spare rubber fuel hose of the right size. Can I use fuel hose or will it not cope with the heat?

I used this as the bleeder to the header tank. I hope it is OK!!

i have used it for the water pipes aswell

Iv been running that on my road car for ages. No problems.
