What is proper fuel pressure, etc ?
What is the fuel pressure regulator output?
Just realized in my custom application the fuel pump inside my Polaris RZR tank I am using has a regulator on the output of it and it lists 270kPa which is about 39 PSI. So, the fuel then goes to the RC51 through its regulator ... I am double regulated ... any issues with this? I know other types of regulators only perform well with a high differential pressure but not familiar with these in line fuel type mechanics. Or, perhaps I should eliminate the RC51 regulator since it seems to be one of the most common issues? By chance anyone ever looked to see if removing/bypassing this regulator would be easy? Part of the reason I am also asking this is my custom dyno tuned Power Commander map shows I was way lean from about 30 to 100% throttle (10 to 20 percent more fuel needed in the custom map) so have always had my concern about fuel flow, pressure, etc. It runs fine though with the custom map as far as I can tell but maybe I am missing some power ...

. But, the frame is beef'd up too
