808DA6 Posted August 29, 2008 Report Share Posted August 29, 2008 Pretty sure larger is going to the carb and the smaller is the return. That's the route that's on my truck. -Brian Quote Link to comment

datzenmike Posted August 29, 2008 Report Share Posted August 29, 2008 L20B motors had a fuel return line, but I don't think others did. It may be the tank vent that eventually connects to the PCV valve to draw away and burn the fumes. On later cars a charcoal cannister was used to store fumes when the motor wasn't running. If it's a fuel supply line then it should be submerged and will bubble if you blow in the end. If it doesn't then it's likely a vapor vent. Quote Link to comment
