I GOT A 1999 HYUNDAI SONATA V6 37,000 MILES. I THINK I HAVE TO CHANGE THE FUEL FILTER. PROBLEM IS I DONT KNOW WHERE ITS LOCATED. I ALREADY BOUGHT THE PART.

...ANYWAYS HERES THE DRIFT; ABOUT 2 -3 MONTHS AGO I DECIDED TO GET A FUEL INJECTOR CLEANER GAS TREATMENT THINGY...I BOUGHT THAT ONE LUCAS BOTTLE THAT TREATS UP TO 100 GALLONS. I USED IT ALL IN ABOUT 2-3 WEEKS. I WAS JUST RECENTLY TOLD THAT BOTTLE IS SUPPOSED TO LAST ME AT LEAST 3-5 MONTHS, I SUPPOSED IT ALSO DEPENDS ON HOW OFTEN I HAVE TO FILL THE TANK-IDK. SO SHORTLY AFTER I FINISHED THE BOTTLE, MY CAR STARTED TO NOT WANT TO TURN ON AS FAST AS IT USE TO. AND SOMETIMES WHILE IT TRIES TO START, RIGHT AFTER IT FINALY TURNS OVER, I CAN SMELL GAS, EVEN WHEN I DONT TRY TO GIVE IT GAS TO HELP IT, WHICH WORKS BETTER IF I DO. DOES THIS SOUND LIKE I MESSED UP THE FILTER WITH TO MUCH LUCAS ALL IN A SORT AMOUNT OF TIME??? IF SO WHERE IS THIS PART LOCATED??? PLZ, ANY AND EVERY HELP IS GREATLY APPRECIATED. THANK YOU VERY MUCH.
