Ok I know its not recomended to run a FPR on the inlet side but I need to stick to a budget and get this thing running asap. I dont give a crap what power I make at this point as long as it runs for the rest of the season safely. I want to know if blocking off the return line on the truck rail and running a return regulator such as the aeromotive 13101 will be safe for the set up in my sig with a single external walbro and 60 lb'ers...

 

Blocking the "return" line on the truck rails?? Use that for your regulator and run a return line back to the tank. Or I have easy swap kit solutions give me a call I will help you figure it out.
