Read Kyle's response while humming the banjo theme from Deliverence and it will make perfect sense...

does this help

 

I know this is an old thread but wouldn't this put the regulator before the rails. Which is what everyones saying not to do? Just curious

 

I have had mixed reviews and answers on this.. I am going to run it just like that with the FPR before the fuel rails.. I have seen it done with good results, also this is the way it is set up on F bod's..

 

You can do it both ways, i have had success in both applications..... All its doing is setting a regulated pressure on the rails wether its dumping fuel off to the gas tank before or after the rail....I currently have it after fuel rails and vacummed advanced

 

With a returnless system, the regulator is always before the rails. Return puts it after, just how they function

My old returnless setup for a NA engine

Very nice
