What is the fuel pump and how does it work?

The fuel pump supplies pressurized gasoline to each of the fuel injectors in a car’s engine. The fuel pump is powered by a compact electric motor and is located in the vehicle’s gas tank. The pressure and output of the pump are controlled by a regulator. Filtration of the fuel occurs either in the fuel tank using a pickup screen or externally with a replaceable filter mounted in the fuel supply line.

When to consider replacing the fuel pump?

A high quality, OEM fuel pump can last indefinitely. However, as with any electro-mechanical component, a fuel pump will eventually degrade and fail. If it fails to produce adequate pressure or completely quits operating, it will need to be replaced. This failed condition can sometimes be preceded or accompanied by one or more of the following symptoms:

  • Car won’t start or unexpectedly stalls and won’t re-start. A failed fuel pump may prevent a car from starting or stall it.
  • Check engine light is on. Sometimes a fuel pump will fail slowly, and that means the fuel pressure and volume slowly degrades. The lack of fuel may result in the engine operating without enough fuel relative to the amount of air, causing the check engine light to appear.
  • Whirring noise from fuel tank. As a fuel pump fails, you may notice a whirring or humming noise coming from the fuel tank area, toward the rear of the car. If the noise is from the fuel pump, failure of the pump is often imminent and you should replace the fuel pump at your earliest convenience.

How do mechanics replace the fuel pump?

  • The fuel pump is tested to be sure it isn’t functioning.
  • Should the fuel pump be faulty, it is removed from the tank through an access panel above the tank in the passenger compartment.
  • When no access panel exists, fuel is first drained from the tank and then the fuel tank must be lowered from the vehicle to gain access to the pump.
  • In all cases, fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump must be removed.
  • Once the pump is out, any reusable brackets and pick up screens are attached to the new pump, then the new pump is installed.
  • If the fuel system uses an in-line external filter, a filter is often replaced. All hoses and electrical connections are re-established.
  • Fuel is added to the tank and the engine is run to test for leaks.

Is it safe to drive with a fuel pump problem?

Usually, it’s still safe to drive, but the pump may lead to an overheated engine and catalytic converter. Complete fuel pump failure can leave you stranded out on the road, but many times a car won’t start before initially driving.

However, if the fuel pump problem involves leaks of gasoline or vapors, it is unsafe to continue driving, and should immediately be checked by a qualified mechanic.

When replacing the fuel pump keep in mind:

  • Prior to replacing, the mechanic will power the fuel pump directly to confirm that the issue is a failed pump versus a faulty power supply to the pump.
  • Unless the fuel filter was replaced recently, whenever the fuel pump is replaced a new fuel filter should be installed.
  • When failing earlier than expected, the power supply should be verified because a voltage drop in the fuel pump circuit can lead to overheating.
  • Should the fuel tank be lowered during the repair, the fuel tank straps and fasteners should be checked for excessive corrosion and replaced as needed.
  • The fuel in the gas tank cools and lubricates the fuel pump. After installation of a new fuel pump, it’s wise to keep the gas tank at least a quarter full to maximize the life of a new fuel pump.

Dodge Avenger V6-2.7L - Fuel Pump - Salt Lake City, Utah
Joseph had a tough day, I think. But he never let it show. The fuel pump on my car went out. Not a cheap, nor easy, fix. Although Joe had been delayed by the job previous to mine, he was sure to call and let me know about the delay and when he would arrive. My appointment was at 1:00 PM and Joe arrived at 1:20 PM. To be honest, technically, he was on time. YourMechanic makes it clear that you should allow for a half hour window from your set appointment time in which to allow your assigned mechanic to reach you and start the job. People need to understand and have patience that with a mechanic like Joseph in such high demand, he has a busy schedule. I should know, I waited five days to get him around to the major fix on my car. With that kind of demand and being a mobile mechanic, issues arise. I felt really bad because of an issue with my repair that caused Joe to be delayed for two additional appointments. It turns out, as Joe was working on replacing my fuel pump, the new fuel pump given to him by his parts distributor was the wrong one. OH NO! Joe knocks on my door and explains what has happened and the delay could cost an hour. I really empathized with his situation about the oversight by the parts distributor. It turns out that the part in question was apparently labeled as the right part through their ordering system, but the actual part was not correct. Had this not happened, Joe would have been ahead of schedule. I bring this up because it's important to give appreciation and understanding in situations like this and realize sometimes things don't go according to plan. I certainly don't blame Joe, nor the previous customer, that delayed him from getting to me at the "set" appointment time. So I would hope the other customers would show the same respect. Joe did a phenomenal job. He was done and wrapped up just before 5:00 PM. I was happy for that. I didn't want him to be working in the dark on my street. Sadly, I don't have a garage like most people do. So when I had this car towed home, we had to drop it in the street; as it was the safest and most convenient way to get it off the tow truck. In the end, I'm happy with what Joe accomplished, his communication and his friendly attitude and quick turnaround when dealing with the wrong part. I honestly want no one but Joseph from YourMechanic working on my car. Like, fer realz.
