This work involves a number of steps, which must be done precisely and with the proper tools to ensure the correct installation. Most of the time, it starts with diagnosing the problem to verify that the fuel pump is indeed where the issue lies. Symptoms of a failing fuel pump are hard starting, rough idling, reduced power and fluctuating pressure. A mechanic might test the fuel pressure, it should be between 35 to 65 psi for gasoline engines (much higher for diesel).
If the fuel pressure has been confirmed, replacing the fuel filter starts with releasing any remaining pressure in the fuel system and preventing any of the fuel from shooting out when its lines are disconnected. You do this by unplugging the fuel pump fuse or relay and running the engine until it dies##. Step 2 is to disconnect the battery to ensure there are no electrical sparks that could ignite a fire when you install your new relay after the relief of pressure.
Fuel Pump: For many vehicles, the fuel pump sits inside the fuel tank; as such, you have to drop the tank to replace the pump. For one, we have to jack the vehicle up safely, unbolt the fuel tank straps and lower it gently down. Some cars, especially with regard to contemporary sedans have an access door. that is if the car still use a rear bench – under the back seat which provides direct entry to the pump without needing to lower and take away out the tank.
Once the pump is accessible, remove fuel lines, electrical connections and fuel level sensor. Get out your label maker or camera and mark everything carefully so you can put it back together properly. After removing the old pump, the new pump is installed in a reverse order with attention to sealing and connection of all components.
For a standard fuel pump alternative, you can expect 2 to 4 hours of work whereas it might change based on the make and model of a car. Fuel pump replacement costs range and the fuel pump itself can be purchased for between $100 -$500 as labor costs add another $200-$400 if done by a mechanic. If you can do the replacement yourself, that saves on labor but it takes skill with a wrench.
One element of that replacement you want to also keep in mind is to check the fuel filter and potentially replace it at the same time as a clogged fuel pump can exert additional strain on your new purchase and bring its service life back down. Fuel Filters: Fuel filters typically require replacement between 20,000 to 40,000 miles and fuel pumps last somewhere between 100,000 to 150,000 miles.
General Motors even issued a large recall in 2019 for some 53,000 vehicles because of bad fuel pumps that demonstrated the degree to which normal vehicle operation depended on properly functioning fuel pumps.
As Elon Musk noted, "Every single part of the system needs to work in perfect harmony or performance is degraded. This is the same philosophy that should guide how you approach any fuel pump replacement, because one mistake or oversight during installation can easily translate into a performance problem or safety concern later on.
So, if you are on the lookout for a fuel pump to be changed than visit us at Fuel Pump we have numerous models that matches the individual requisite and makes vehicle reliable.
