Re: Corvette Regulator with a stock 5.3 return line Fuel rail
Returnlrss rails will fit as long as they come from another truck engine. The injectors are different from flex and non flex and return style rails are flex and non flex specific. If you're going to go the returnless route, those rails are cheap, but I guess if you can't find any in the yards around you that makes it a little more difficult, however, keep in mind, if the plug you cap the rails with fails, it will likely leak fuel on a hot engine. Also, you need to remove and plug the regulator, when those fail they leak fuel too, only you generally don't notice it because the vacuum hose sucks it into the intake, but it you do notice it running bad.
