Auto Tips: How to check the fuel pressure of the car at home, performance will increase in one minute, know here...


The fuel pump is an important part of the powertrain system of the car. It transfers petrol or diesel from the fuel tank to the engine of the car. The fuel pump of a car can be either mechanical or electric. A well-functioning fuel pump enhances the performance of the car engine. The most common fuel pump used in today's cars is electric. Most of the time the fuel pump is located inside the tank. A bad fuel pump can cause a lot of problems and can leave you stranded anywhere.


In some cases, the fuel pump of the car starts malfunctioning before it fails. It is always said that the performance of the fuel pump should always be checked. This can save you from expensive expenses or dangerous situations. A commonly reported problem with car fuel pumps is low fuel pressure which causes them to overheat and fail quickly.

Bad fuel pump symptoms
Here are step-by-step instructions on how to check fuel pressure in car fuel pumps. Before that let us have a look at what are the symptoms of fuel pump failure. The most common symptom is the low engine power delivery. In such cases, the torque output is insufficient even when the escalator is pressed directly. Low fuel pressure usually occurs when the pump is doing a poor job. Checking the fuel pump pressure of a car requires some tools. These include a screwdriver, fuel pressure gauge, ratchet, and socket.

Test pressure like this
First, park the vehicle and apply the parking brake. Allow the engine to cool. Then locate the fuel pressure test port where you will be working. Make sure to put a piece of cloth under the test port, because while doing the pressure test the fuel will come out and it will fall there. After placing the cloth under the test port, apply the pressure tester to the port. Then start the engine and start recording the pressure reading.


How to know whether the fuel pump is working or not
You can refer to the company's manual to test the pressure of the fuel pump. Some manufacturers recommend checking pressure with the engine running at a particular RPM. If the pump is not able to give the required pressure then the pump may fail to send fuel to the engine. A specialized port-injected vehicle requires a fuel pressure of between 30 and 80 PSI. The vehicle manual states the required fuel pressure. If you think the fuel pump is going bad, it's time to have it checked by a mechanic.
