Routing of Fuel Lines into F.A.S.T. Rails I am pretty new to fuel injection so please bear with me. I got a great deal on a 5.3 with aluminum intake and FAST fuel rails already installed. The fuel system I have setup for it is a Bosch 044 fuel pump and a corvette reg/filter. The reg/filter only has one outlet heading towards the engine. The Fuel rails have a crossover already on the front, but the rear of the fuel rails (towards the firewall) consist of a 6 and 8 AN fitting. What should I do in order to just run this one already already regulated line into the fuel rails. Should I...
-Cap off the rear of one of the fuel rails?
-Create a Y at the rear of the engine and go into both rail?
Im not sure feeding only one side will cause the other side to somewhat go lean, or if feeding both rails at the same time will cause problems.
This is all going into a 70 Chevy short bed pickup, so I am just trying to go for a clean look under the hood. Its only going to be 350 hp when done as well.
