A full fuel system service should include both a chemical cleaning of your system and replacing any worn components. This could include your fuel pump, fuel filter or fuel injectors. Fuel filters should be changed every 30, miles or at the interval specified in your owner’s manual.

The fuel system is a key car system at the boundary between the chassis and the engine teams responsibilities – the chassis team designing and operating the fuel cell and lift pumps and collector, and the engine team taking responsibility for the main fuel pump, filters and injectors. Apr 11,  · Vacuum System: This system uses engine suction pressure to suck the fuel from the main tank to an auxiliary tank. From there, the fuel flows to the carburetor float chamber by gravity. This system is now obsolete. Pump Feed System: Most present-day cars use this system. Old cars used to have a carburetor that fed fuel to the engine. However, carburetors were far from efficient and auto manufacturers eventually developed a fuel injection system that electrically controls fuel injection. These complex systems provide accurate fuel monitoring so that when you step on the gas, the fuel injector delivers just the right amount of fuel to your engine.

A fuel pump, which can be either mechanical or electric, does the job of transferring gas from the fuel tank to the engine. The pumps can overheat and fail if your car is low on gas. You have to know how to check fuel pressure because it drops when the pump is weak, signaling that you need to take immediate action. The fuel injectors spray fuel directly behind the intake valve into the intake manifold. These systems normally have one fuel injector per cylinder.

These systems use one or two fuel injectors which are mounted on top of the intake manifold. They spray fuel into the throttle body like the conventional carburetor. Sometimes if the gas pedal had been depressed, a vehicle is moving along normally at a consistent speed and then, it will pick up and surge forward out of nowhere, which is caused by irregular resistance within the fuel pump motor. The temperature of the car can help one to predict a fuel pump emergency. If the heat rises and the car stalls, pay attention to your temperature gauge because this may mean the fuel pump motor is having problems.

If it continues to stall out, the fuel pump is apparently starting to deteriorate and needs to be replaced. Fuel pumps have a relief valve; if the relief valve is failing to open, more fuel than necessary will flow into the engine system. If your vehicle normally gets decent gas mileage and then suddenly becomes a gas hog, there could be an emergency under the hood. The fuel pressure gauge illustrates how much fuel is getting to the engine.

You can check that gauge while someone else is revving the car. Drivers who fail to notice the warning signs above will eventually end up with an engine that refuses to start. When a fuel pump completely malfunctions, fuel cannot get to the engine upon ignition.

If this happens, the engine will crank and rev but never start. A car is put under huge stress when climbing a hill or hauling heavy cargo.

One of the best indicators of a fuel pump failure is found on the road while driving your car at a consistently high speed. If the vehicle suddenly sputters and then resumes regular performance, there could be something wrong with the fuel pump. When the pump is struggling to supply a constant stream of fuel to the engine at the proper pressure, this engine sputtering happens. A pump shows some subtle warning signs before going completely out of order.

It is possible to about the total breakdown and costly repairs if you can detect the warnings and diagnose the problems. The symptoms generally include the check engine light to come on, jerking of the car, stalling the engine, and low engine power. If you know how to check fuel pressure and test the fuel pump, you will be able to diagnose the problems.

In most cases, the pump fails because of the failure of the fuel filter. The modern automobiles have a filter in the fuel tank that you can change at the time of replacing the pump. However, older vehicles have an external filter that needs replacement after 20, miles. If the pump is showing warning signs, you should replace the filter first.

If your car has an electric pump, you can do the multimeter testing to examine its health. Take a multimeter with an amp clamp, turn the pump on, and place the amp clamp over the positive wire going to the fuel pump. Start your vehicle and record the amperage reading on the meter. Similarly, you have to get the voltage reading by placing the meter leads on appropriate terminals. Most car models have a test port on the fuel injector rail for the testing of the pressure.

You may need to remove the fuel line and use an adaptor for the testing. Install the pressure tester to the test port when the engine is cold.

Turn the ignition key and then the engine and record the pressure readings both times. A car with a port-injected pump should yield a reading between 30 and 80 PSI.

If it does not match the required pressure, you should take the car to a servicing shop for maintenance and pump replacement. Tsukasa Azuma is an awesome car blogger of Car From Japan.
