has anyone ran a single regulated fuel line to the throtlle body and blocked off the stock regulator and put a plug in the fuel return fitting on the back of the throttle bodie. does anyone know if this will work for sure? befor the car was carburated so now i want to put it back to the original conditon and get it running smoth agian, i have a holley bypass style regulator with an fittings for the return and steel beraded lines all ready hooked up, i would rather not change them if the system will work nice

 

so you want to go from carbureted back to tbi? fuel injection systems have to have a return line as far as i know
