FUEL PUMP

Its located in the fuel tank and you can get a estimate here https://repairpal.com/estimator/dodge/caravan and find a shop here https://repairpal.com/dodge-repair-in-chambersburg-pennsylvania

back left side right by the back tire

It is located inside the gas tank. You have to drop the fuel tank from the bottom , i think there are three bolts, two holding the straps and and one on the edge of the tank. Once you do that you will see the fuel pump, you need to remove the screw cam then pull the pump out. hope this helps.
