I am installing a return style fuel rail system (FAST fuel rails) on an LS1 out of a 2000 camaro I purchased. I had swapped this LS1 into a jeep wrangler before I figured out that I should have purchased an LS1 from a 97 or 98 corvette to work with my fuel cell like I wanted. My question is does it matter which fuel rail is the inlet and which is the return? Also, any other helpful hints on my swap?

thanks
