4 easy steps to Check Your Fuel Pump

If replacing a fuel pump is not the proper course of action for a fuel-related issue, it could prove to be an expensive error. Before blaming the fuel pump, a fuel system should be thoroughly examined for pressure, volume, and electrical integrity.

1. Security first
Examining fuel pressure and flow on a return fuel delivery system is what we will do now. The most crucial thing to keep in mind before beginning any diagnostic testing is that releasing fuel under pressure might result in fire and damage. So prioritize safety. Work in a well-ventilated location, put on safety goggles, and avoid smoking or having anything that could catch fire nearby.

2. Gas pressure
Check the fuel pressure first. Once the car is running, let it idle. Install a fuel pressure gauge, turn on the pump, and record the reading. After that, compare it to the manufacturer’s requirements. You should take action if the pressure is low. Perform a fuel volume test to see whether the correct volume of fuel is being delivered to the fuel injectors if the fuel pump is supplying enough pressure.

3. Make use of a flowmeter or a glass measurement vessel.
Using a flowmeter is the most precise method of testing fuel delivery. Although some repair shops might have that, you might not. Here is a method for running a timed fuel delivery test that is fairly reliable. Use a suitable measuring container and exercise caution. Because fuel can corrode or fog plastic, glass is a suitable option.

4. Test
Starting the car and letting it idle will trigger the pump to turn on. You must take a fuel sample while the pump is running for five seconds. Check your manufacturer’s specifications to determine if your pump is delivering the right quantity and your system is operating properly. The pump should deliver a particular amount of fuel within that time limit. To determine it, you might need to convert milliliters per second to gallons per hour.
