My setup is a bit different....I used the Aeromotive A1000 FP mounted in tank with a -10 Feed line to a distribution block with two -8 lines running the rails in parallel. The return is two -8 lines to an SX FPR with a single -8 return line to the tank. I used all Aeromotive lines, fittings, filters, and pump. I am also using Keith's rails with 72/160lb top feed injectors.

 

Here's a good write-up on an RX-7 custom fuel system.

 

How-to for rails and injectors is mostly done...
