Good fuel pump vital to your vehicle's performance

In your vehicle, electric fuel pumps run constantly. And after many years of service, they can experience wear.

Your fuel pump relies on fuel passing through it for lubrication and cooling. Consequently, fuel starvation can be another factor that accelerates wear and may even cause pump damage under certain operating conditions.

If your fuel pump stops working (i.e., no noise, no line pressure), the first thing that should be checked is the pump's voltage supply and electrical connections. An open relay, blown fuse or loose wire may be all that's preventing the pump from working

Measuring static output pressure and fuel delivery are the two standard diagnostic tests your tech can perform that can be used to determine a pump's ability to deliver fuel.

If static pressure or the volume of fuel delivered is less than your car manufacturer's specifications, your fuel pump needs to be replaced.

How to Select the Right Pump

If you're fuel pump does need replacing, selecting the "right" replacement fuel pump involves more than looking up the year, make, model and engine size of your car. It also means choosing a pump that meets all OE performance specifications and fits the same as your original.

Here's a useful tip for your professional service tech: When replacing a fuel pump, be sure to choose a replacement unit made by a manufacturer that provides you with the proper suction filter and installation kit.
