Buy 2 cans of fuel system cleaner and pour it in the tank with a full tank of gasoline. I use Sea Foam or Berrymans B12. I prefer the former after being a user of the Berrymans for years. You can purchase it as most any parts house and also at Wal-mart for best price I've seen lately. Also buy a large can of Carberator cleaner/starter fluid (GumOUT) and clean the exterior real well. be sure to wipe up any left overs so as not to start a fire. Let it breath for a while so vapors evaporate. Change the fuel filter. This is a must. Easy to get to under the car, or have the mechanic replace it. You will need a set of car ramps or a lift. If using a hydraulic jack put jack stands under it. Don't us concrete blocks like rednecks do. They can kill you!
