We have a ‘49 3100 AD Chevy PU with a 235. We ordered new tank and stainless steel fuel lines from classic parts. The fuel lines that arrived are a different diameter even though I ordered the ones for a ‘47-‘50 Chevy Truck. (See pics). The old line from the carb is 3/16” inside diameter and new one is 1/4” inside diameter. The one coming out of the carb seems fixed, and not removable. Is this an easy fix or do we need to order a different fuel line? Thanks!
