Hello need more help please i bought my car with an unfinished 2.0 blacktop with gsxr bodys and st170 mani and rail conversion and mostly everything is done but one problem is the fuel pipes to rail,right the car has just one feed to the rail but it goes through a fizzy reg then on to the end of the st170 rail but the 170 rail has a pipe for return .Do i just blank it or do i have to run a return pipe back to the tank and does the fizzy reg fit on the feed side of the pipes or return.

 

Problem solved thanks to a good friend.
