How To Install A Fuel Pump?

Pumps come in every form, so finding the right one for your vehicle can be daunting. There are two types of pumps: mechanical and electronic. Mechanical pumps are the older style and require you to operate them manually. On the other hand, electronic pumps require no user input and operate automatically. Which type you choose is up to your preference; both have pros and cons. If you’re installing a new fuel pump, you’ll need to remove the old one. You can remove the screws that hold it in place or use a universal joint puller tool. Once it’s out, you can either discard it or save it for later if you plan on replacing the pump with the same model. Next, measure the distance between the pump outlet and your fuel tank. It will help determine the size of the pump that will fit properly. You can also consult a mechanic to get an exact measurement – they will be able to verify that your pump is correct for your vehicle. The guide will outline the steps necessary to install fuel pumps on a car.
