[Land-speed] Heat Protection..

[drmayf]

I have added fender wells to the SUnbeam. As a consequence it is gonna 
get hot in the engine room. My water injection line is 1/4 od high 
quality air line. I would like some suggestions for sliding something 
over it to gie it some heat protection. Yeah, I know I can get 
firesleeve or some such, but the cost is similar in dollar size to the 
bailout package for the length I need. So what else can I slide over the 
line?
