Of course, wrapped around the exhaust it will keep heat out the engine bay by keeping it in the pipes - Might be worth trying it that way...?minor_hickup wrote:How about that exhaust wrap you see advertised for manifolds? Surely if it can keep heat in it can keep it out! I don't know how easy it would be to put on the supply to the pump. Sorry if this has been suggested before.

The local good stuff and stick on tat factors has some wrap for not silly money, I'm thinking of trying it sometime (though no doubt my insurance company will say no...) just to see if it really can help underbonnet temps at all.
