There is a large metal fuel line that runs infront of the engine on the crossmember traveling just above the brake line splitter. It then goes to a rubber line near the steering gear and to a plastic canister on the raditor support. There are few rubber lines from the canister to the carb. An employee of mine crimped the metal line installing a ord steering box brace. Is this line a return? Just wondering if it was under pressure or if we could cut it and route it around the brace with a rubber patch.
