#119502, "Hahn Fuel System making me run too rich and then too lean...Cheapest way to fix?"
I currently have the old Hahn Racecraft fuel system that came with the stage 2 turbo kits. It has the Accel inline fuel pump outside of the tank along with a Cartech FPR on my firewall. I keep getting CEL's for running too rich. I adjust the FPR and then I am running too lean. Is this fuel system worth keeping? What is the easiest way to upgrade? Is the Accel pump good to keep? My first pump is still the stock pump and the injectors have been changed to 390's. Should I go back to stock injectors for now?
I want to eventually get the Portfueler or Emanage but do not have the money now. Should I get another FPR? Would that help for now? I am trying to pay for a honeymoon and a garage so cannot spend $1200 right now but the car sits in the garage due to my problems. Please offer any advice you may have.

get a different FPR, and you can replace the external pump and intank pump with a walbro intank one (not nearly as loud). Or put in the Walbro and keep the inline. But change the FPR that will help you. Going back to stock injectors will help, but keep in mind keeping your psi levels low, as the stockers will be pretty much maxed.
