I don't have a picture of my engine compartment showing the fuel line, I ran the 1/2 line in the same way as the stock 5/16 was ran by the factory My car is a 1971 Duster with a BB and fender well headers, the headers don't get close(close meaning less than 6 inches) to the fuel line anywhere other than when it hooks up to fuel regulatorThe fuel regulator is mounted on the backside of the elephant ears directly under the alternator, it might be close to six inches there. the motor and headers are out of the car right now so I can't measure them to see, sorry
