If you look at the gas line on my 640 you will see it snakes up inbetween the intake/exhaust manifold pipes. I don't particularly care for fords design on this one. I usually run my lines around the front of the engine. Your sediment bowl might have been turned around so that the gas line hookup would be on the outside instead of the inside.
