Re: Quick question: Return line-TBI to Carb

3/8" feed and 5/16 return is the std for these rigs over the years .

did you bypass or swap the intank pump ? you can NOT suck threw a intank pump and feed the engine . also the pump pushes fuel better than sucking fuel .

if you still have the intank pump get a return style regulator and plumb it in and there you go problem solved .
