SOURCE: poor gas mileage
Do you have a gas smell in vehicle if you do there check and make sure that you are NOT loosing gas by a leak in the fuel line that was replaced or anyother part of the fuel sytem for that fact. If there is NO leak then the pressure from the pump may be too high and therefore dumping too mucj fuel into chambers but if this is true the vehicle may have a hesitation on take off or may run a little roughand a rich burning smell from exhaust, Check these things out make sure that the fuel pressure at the injector rail is correct refer to your repair manal for exact specs,because I NOT sure what it its, good luck and thanks for using FIX YA

Have you changed your gas station? I am not getting good fuel mileage when I fuel at cheaper gas stations. Try Exxon or BP and see if that changes anything.
check your fuses and relays

Check the fuel hose and clamps from the filler to the tank .check hose for cracks . The smell will probably be strongest in the boot.
