I am changing out the crossover on my big block Chevy. I am installing the type that has the fuel chiller. There are two fittings on each end that you run your fuel line through. Can you guys advise me how you plumb this? Thanks in advance!

Does anyone even know which one I am referring to? Don't know the brand name. Bought it used from a fellow here on the forums. I will post a pic. If I need to.
