The lines go along the frame rails. But originally they ran too close to the exhaust. 440's are notorious for vapor locking. There are some mods that will help. Change all the fuel lines to 3/8 inch. Install a pusher electric fuel pump close to the tank. This Wii pressurize the fuel line up to the mechanical pump. Higher pressure rases the boiling point if the fuel. Try to buy premium fuel that does not contain methanol. You should try to keep the engine compartment cool.  Change the clutch fan to one from a 454 Chev. They cut in sooner. Don't buy a cheap one. Hope this helps.
