Fuel Rail Differences, S4 and S5
I've got an NA S5 manifold to put on an S4 motor. The S5 manifold I got didn't come with either fuel rail, so obviously I need something other than the S4 NA fuel rails. Ideally, I know I need S5 NA fuel rails, but my question is, will any other FC fuel rails fit the S5 intake manifold? Since the S5 NA fuel rails are hard to find, I was hoping something else would work.
Any help is appreciated.

You could probably finagle an S5 TII primary rail into working, but the S5 TII secondary rail would end up backwards. And that's if it will even mount properly on the outside of the UIM. You could force things to work if you want to get creative, but it's really over-complicating it. S5 NA rails are easy to source; just use the classifieds.
