Introduction

• Like any other vehicle metal equipment, the fuel
  pressure regulator can also fail, leading to many
  mechanical problems.
• In case your car is emitting a thick, dark smoke
  and the oil is leaking from a tailpipe, these are
  the evident symptoms of a faulty or bad fuel
  pressure regulator.
• The fuel injection in a vehicle is equipped to
  supply fuel to the car engine with a constant
  optimal pressure.

• There is a spring situated inside the engine
  pressure regulator which pushes inside the
  diaphragm and maintains the pressure inside it.
• The tension in the spring is preset by the
  vehicle manufacturer so that the driver could get
  the desired fuel pressure.
• The fuel pump has a job to supply enough fuel
  when the pressure strikes to curb the spring
  tension.
• The additional fuel that is not required is
  reverted back to the fuel tank through the fuel
  return pipe.

Symptoms of a Bad Fuel Pressure Regulator
Blackened Spark Plugs

• Locate the engine spark plugs under the hood of
  the car, remove it and examine the ends of it.
• If the ends are sooty, unclean and blackened, it
  could be a sign of bad fuel pressure regulator.
• If you find even one plug in that condition,
  examine the rest of them too.
• A blackened spark plug is an indication that the
  engine is burning oil at that head.

Fuel Leaks

• Another potentially dangerous issue with the bad
  fuel pressure regulator is the continuous fuel
  leakage.
• When the diaphragm or the seals of the fuel
  pressure regulator fail, fuel leaks can take
  place.
• A faulty fuel pressure regulator will not only
  cause gasoline leak, it can also give birth to
  certain mechanical and performance issues.
• At times of fuel leaks, a noticeable fuel smell
  will permit the air and your vehicle may display
  certain engine performance issues.

Black Smoke

• Black smoke coming from the vehicles tailpipe is
  an indication that something is wrong with your
  vehicles fuel pressure regulator.
• If you are seeing black smoke coming from the
  exhaust then you should have the regulator
  inspected or if the condition is worse, have it
  replaced as soon as possible.
• Your vehicles tailpipe should only emit white or
  gray smoke, black smoke is a call for immediate
  action.
