New Fuel Rails and PRV

As I said in a previous blog post, we had trouble getting enough fuel to the first 427 build at 700 chp.  I believe the fuel system was not up to the task, so contracted Kinsler to develop new rails capable of feeding more than 800 chp.  These are custom made and feature .685" ID, with -8AN inlets and outlets.

I will have to run new lines from the pumps to the rails.  Will feed the fuel inlet into the drivers side with -8AN line.  Connect the two rails in the front--there is no A/C compressor in the way, so plenty of room to route the line.  At the end of the passenger side rail, I will connect the pressure relief valve, set to 75psi.  A -6AN return line will send the excess fuel back to the tank.

With the relief valve set to 75psi, my 30lb Red Motorsport injectors will flow the equivalent of 44 lbs/hr-- enough for over 1000chp.
