money. i looked up "AN" lines and fittings and all that crap. this was the cheapest way to do it. using a flair tool cant cost much or any more tho.

should you build a set like this, you install the rail first, then drop the core and blower on. only draw back is ill have to take the lines off to get the rail off with the blower still on. lines are trapped under the snout and tb.
