No guarantees -- the rails do look different on Fox body, so it's possible they have different size fuel lines. Why not just use the fuel lines on the existing 94/95 engine? Or grab some from a junk yard. Couldn't cost that much.
actually the rails are better on the 94-95 cars as they had a larger design that could flow more fuel. A cheap upgrade for fox guys that need a better fuel system. They are diff. from the 87-93 5.0 cars.
