Mechanical fuel pumps are usually located outside the fuel tank. These pumps mimic the diaphragm pumping action to supply gas to the carburetor from the gas tank. Electronic fuel pumps can be found inside the gas pumps and work by spraying fuel into the engine chamber. Why Does My VW Fuel Pump Keep Going Out? Your Volkswagen fuel pump should last more than 100,000 miles. However, it might suddenly fail due to electrical faults, fuel contaminants, or old age. Fuel pump problems can prevent your car’s engine from starting. It can also cause performance and drivability issues. How to Tell if Your VW Fuel Pump Assembly is Going Out?
