Scott,

I'm still running the OE CIS fuel pump, accumulator, and fuel filter set up. My current fuel system (based on the installation diagrams with my kit) is a dead leg configuration. My current FPR has 2 in/out ports plus a return port at the bottom.

I know from reading some of your posts on the subject of fuel system design that you recommend a flow through system as the dead leg system can be prone to vapor lock, etc.

I think once I get the fuel pressure turned up to the 55-60 psi range and see the effect on VE table cell values and injector pulse widths, then I'll start planning the next step with my fuel system set up using a flow through design with the Radium FPRD-RA fuel pressure regulator with dampening.
