Using Stock F-Body Fuel Sending Unit: Fuel Line Configuration Question I am running a stock F-body fuel sending unit (with built in regulator) and am wondering how to configure my feed and return lines. I know that many are running the Corvette FPR/filter set up which has both the feed and return running directly to the FPR/filter, but since the F-body sending unit has the built in regulator, how should I run my fuel lines? Would I just "T" the return line in the the feed line and put the filter in between the "T" and the fuel rail?

Have the dual lines is a better way to go from what I hear,just run two lines from tank to fuel rail,put a in line fuel filter in the feed line somewhere!the older dual in out fuel rails have built in fuel regulator!

Also, assuming I use the feed-only fuel rail, how would I configure the return line given that i'm using the stock sending unit?

If you have an LS1 fuel sending unit you will need to put a Y in the line back by the pump and use a returnless fuel rail (LS1 f-body's had a block that 3 lines went into)
