What is a fuel pressure regulator?
The fuel pressure regulator works by adjusting the fuel pressure and transferring any extra fuel to the tank. If the fuel pressure regulator fails, excess fuel will seep into the engine and contaminate the oil.
How do I know if I need to get a fuel pressure regulator replacement?
Here are a few symptoms of a bad fuel pressure regulator:
Your vehicle’s fuel efficiency is poor
There’s a gas odor in the engine compartment
The exhaust (tail pipe) emits a thick plume of black smoke
The check engine light is on
Your car repeatedly experiences stalling and engine misfires
How long does a fuel pressure regulator last?
The fuel pressure regulator is supposed to last as long as the car does, but occasionally it will break down. Since mechanics don't usually check the fuel pressure regulator as part of the normal maintenance process, you should keep your eyes peeled for any signs that the fuel pressure regulator is faulty or damaged.
Can I replace my fuel pressure regulator myself?
Drivers who are confident in their DIY mechanic skills may decide to replace their fuel pressure regulators themselves. But because replacing the fuel pressure regulator is a multi-step process, most drivers should leave it up to the professionals.
