Does anybody have a chart or schematic or something showing me where the fuel lines go when they go under hood? I have a fuel leak somewhere (I can smell it and my fuel mileage is suffering) and It's somewhere inside the engine bay

 

If the fuel pressure regulator is leaking mileage will drop and you will smell fuel. The regular is located under the plenum. It has a small hose that to supply vacuum to regulator. Check for fuel in the hose to the regulator as it would indicate the regulator is leaking. The blue circle is where the hose attaches. This is photo was found on the board.
