Fitting S4 NA fuel rail on S5 NA intake manifold?
I'm building up an NA-EFI setup and wanted to avoid turning my awesome new build into a barbeque pit, so I got some uber sweet polished S4 fuel rails with the pulsation dampeners removed. The trick here is I've got an S5 intake that they're going on.
The mounting points for the S5 rail are lower and further apart than the S4, but injector spacing seems identical. Seems like with a bracket this should work.
Has anyone fabbed up a bracket for this, or know of a source for one? The rest of the setup is super clean, would like to keep in that tradition with a nice bracket versus something ghetto-rigged on.

go to FB and ask ERIC on his page.
Rising RPM - Home if he has Rails.I think you need to ask,as you are dealing with N/A and not TII rails.
