Let it be known that your Volkswagen Jetta Fuel Pump is central to the operation of the fuel injection system and is considered as its heart. The fuel pump can usually be located near the auto’s fuel tank, and it functions in two-fold. Because there is a need for the fuel to be pumped from the tank to the injectors, your Jetta fuel pump actually does this job with ease.

Now, the delivery of the fuel can either be under low pressure to the carburetor or under high pressure to the fuel injection system. Because of this, some fuel-injected engines out on the road today have two fuel pumps for this purpose; one for low pressure/high volume supply pump in the tank and the other one is a high pressure/low volume pump on or near the engine.

Another role that the fuel pump does is to create a sufficient pressure so that the injectors will deliver the correct amount of fuel under all operating conditions. It is important to note that the pressure that is developed by the fuel pump and the volume of fuel that it allows to flow should meet the requirements of your vehicle manufacturer. If not, the performance of the engine, your fuel economy, and exhaust emission will be compromised. Replace a failing fuel pump fast rather than suffer a bad ride with your Jetta.
