fuel and confused

Since you got it rebuilt is it running ok? Or is the pump flooding the carb? Yes, Eddy's like 6psi or less or they can flood. If it's running ok, leave it. If it's flooding, you need a regulator or Holley or Demon. If it's still running rough, then it may not be the pump/carb combo?

By the way, I like the Indy's on the back of your Duster. What size are those?

Good luck! If it were me, I'd run a regulator either way. Those race pumps are 120gph right? Even if I switched to a Holley, your on the upper limits I'd say. Doesnt Carter recommend a regulator with that pump? I may be mistaken...
