What would be ok to use? I know stainless would prolly be preferred but what about galvanized or alumanized? This is for engine coolant by the way

 

I used 316 stainless for my upper radiator "hose". Powdercoated the outside black.

 

What size and where did you get it?

 

I will have pics in a week or so. I used a C5 upper radiator hose and cut off the bends on the ends. I linked the two pieces with a 1&1/4" x 18" piece of 316 stainless pipe from Verociousmotorsports dot com. I also got the fancy worm gear clamps from them as well (in stainless).

 

I was interested in doing something like that. Can't wait for the pics!!
