I'm currently plumbing the fuel system for an LS1 into a 1st Gen F-Body. I changed the fuel rail so the regulator is @ the engine. The fuel pressure hose is 3/8" and the return is 5/16". Is there any reason why the return needs to be smaller? Am I overlooking something? 3/8" components are a whole lot easier to come by!
Thanks

no problems running a 3/8" or even 1/2" return line. Too small to handle the return flow without restricting it is a problem, but not too big.
