FAST injector spacers on a LS2 manifold ... stock O-rings? When using the FAST injector spacers to use an LS3-style injector in an LS2 manifold, what O-rings are required? The injector will use the stock LS2 upper/lowers I imagine, but I need to figure out what O-ring to put on the spacers.
Do I need FAST O-rings or stock LS2 lower O-rings? FAST was not overly helpful when I was chatting with them the other day when I told them I wasn't using them on their manifold.
Specifically, I'm swapping an LS2 intake onto my LS4, retaining the stock injectors (LS3/LS7-style) and fuel rail (needs spaced up 1/2-5/8" to clear the intake)

Yes I have stock injector o-ring worked fine with the Fast spacer accessory. Used an Aeromotive fuel rail but needed to fab brackets for it to work. FAST should have their kit complete. here is a pic or two. The fuel lines have not been installed but the setup is tied down.
