We’ve made these Primary top feed fuel rails to allow the use of Bosch style (EV1 60mm) top feed injectors (14mm o-ring) in the stock primary locations. These rails are a simple addition to any build on their own or as a compliment to our four port rail in our lower intake.

All rails are threaded both ends for 1/4″ NPT hose barbs or 1/4″ NPT to -AN (not stock banjo).

For better fitment, we also offer fuel rail stands for EV6 style 48mm tall injectors. Please contact us for the EV6 style stands.
