What is the Fuel Pressure Regulator all about?

Cars need to run at a specific fuel pressure. The regulator controls the fuel pressure and returns any excess fuel to the tank. The regulator is important to ensure that the injectors operate properly. If the regulator malfunctions, it can cause the engine to flood. In extreme cases, a flooded engine can be a fire hazard.

You may see liquid on the floor near the exhaust pipe (raw gas dripping from the tail pipe). You may also notice black smoke when the engine is running (partially burnt gas produces black smoke). Not only will the car get poor gas mileage, it also may not pass an emissions test.

Fuel Pressure Regulator-MATROX-1

Keep in mind:

Some fuel regulators are located in the tank as part of the fuel pump assembly. If the fuel pressure regulator has gone bad, it can leak fuel in the engine, contaminating the engine oil.

How it's done:

  • Scan the computer system in the car for trouble codes.
  • Inspect fuel pressure regulator for leakage and proper operation.
  • Inspect for any broken vacuum lines.
  • Remove and replace fuel pressure regulator if it is bad.
  • Change the engine oil and filter if the oil is found to be contaminated.
  • Clear any diagnostic trouble codes.
  • Test drive the vehicle.

Our recommendation:

Any time that you notice something potentially wrong with your fuel system, you should schedule an inspection. There are many signs that a fuel pressure regulator is malfunctioning, and all should be taken seriously. If you notice that your car is getting poor mileage, has gas leaking, has black smog coming out of the exhaust, or isn’t running smoothly, contact a mechanic. A malfunctioning fuel pressure regulator will often illuminate the Check Engine warning light, which is always a sign to schedule an inspection.

What common symptoms indicate you may need to replace the Fuel Pressure Regulator?

  • Poor gas mileage.
  • Smell of gas in the engine compartment.
  • Fuel is leaking.
  • Black smoke coming out of the exhaust (tail pipe).
  • Failed emissions test.
  • Check engine light is on.

How important is this service?

When gas is sent from your gas tank to your engine, the fuel pressure regulator makes sure that the fuel pressure is optimal. The fuel pressure regulator is responsible for returning excess fuel to the gas tank, and making sure that the fuel injectors get the perfect fuel pressure. When the regulator malfunctions, the fuel pressure will not be controlled, and your engine will not run optimally. Your engine will also be at risk for fuel flooding, which can result in serious damage and even fire.

Lexus RX450h V6-3.5L Hybrid - Brake System Flush - New River, Arizona
I would like to rate Peter 10 stars if I could! Here's a guy who's already hit 1000 5 star reviews! That's insane! When two other mechanics cancelled on me for a brake flush on my Lexus RX450h, YourMechanic sent their "best" tech out to do it. And they weren't kidding. Peter is one of the very best if not "the best" there is. Not only did he do the job quickly and correctly but he has an amazing bedside manner. He is one of the most intelligent people I've met in a long time and I had an amazing conversation with him. You can tell that he loves people as well as cars and it is more than just about the money for him. YourMechanic has a superstar here and they should have him training staff for how to treat clients as well as for his vast knowledge about cars, how the subsystems work, and how to troubleshoot and repair them. If YourMechanic continues to hire such top tier guys like Peter, car shops are going to be in trouble. Absolutely amazing service in every way. YourMechanic has brought humanity back to car care and has given amazing mechanics a more flexible schedule so it's a win-win. I really enjoy getting to know the person who is directly taking care of my vehicle. You just cannot compete with that. Thank you Peter. It was a sincere honor to meet you! And what a great accent! If you're lucky enough to book him, definitely do.
