Does anyone know of an upgrade to the primary fuel rail besides the KGParts? I want to keep the same set up that comes stock (primary rail to the secondary rail) but want to run AN line through it all. Anyone have any suggestions?

S4 rails are meaty enough to drill and tap with NPT threads. This allows you to use NPT- -AN adapters. For the stamped S5 rails I've had limited success with TIG welding adpaters to the ends of the rails.
