How to build a weldon fuel system

Gotham is allowing me to show their build up of a fuel system they're installing on a 20B.



The system consist of Weldon pump(biggest electrical pump before going mechanical) , weldon fuel pressure regulator, weldon fuel controller.

3 x 1600 cc injectors

3 x 4000cc injectors





xrp clam shell conectors for the fuel lines



flexible fuel lines, same ones most racers use on drag cars

what kinds of pressures do 4000 cc injectors require at say a 70% duty cycle?
