Description
What Is A Fuel Pump
A fuel pump assembly is the unit in a gas tank that sends fuel to
the engine. Other than the pump itself, the assembly comprises
several other components, each with a special function in the fuel
pumping system. Also known as fuel pump module assembly, the fuel
pump assembly ensures that clean, pressurized fuel reaches the fuel
injectors.
Fuel pump assemblies are usually located in the gas tank, submerged
in the fuel. The main pumping component in the assembly is an
electric motor that spins at high speed to an impeller, several
valves, and a pressure regulator. How does an auto fuel pump differ
from the fuel pump assembly?
The Fuel Pressure Regulator
As the name implies, this is the part that regulates fuel pressure.
Accurate and consistent pressure is required at the fuel injection
system, or the engine will run too lean or too rich. Both scenarios
are not desirable in the fuel delivery system. They can result in
loss of power, inefficient combustion, or even damage.
The fuel pump pressure regulator is essentially a valve that
consists a spring and diaphragm. When pressure is too high, the
valve opens to let excess fuel flow back into the gas tank. Older
carburetor engines have the regulator outside of the fuel tank,
towards the end of the injector rail. In modern direct
fuel-injected systems, the fuel regulator is built into the pump
assembly.
Some pressure regulators, especially, inline fuel pressure
regulators, can be adjustable. An adjustable fuel pressure
regulator allows one to increase or decrease the maximum allowable
pressure. Some come with a pressure gauge and offer more options.
An adjustable fuel pressure regulator with gauge lets you control
pressure to precise levels. This is usually a return style fuel
pressure regulator that mounts in the pressure side of continuous
fuel lines. A universal fuel pressure regulator fits a wide range
of vehicles, which makes it one of the most used types of external
fuel pressure regulating units.
Regardless of whether it is a gasoline or diesel fuel pressure
regulator, this part of the fuel system is one of the most useful.
Too little fuel pressure and the engine runs too lean. Too high
pressure and the engine runs too rich. Although rare, the regulator
can break down and cause reduced fuel pressure. It can also get
stuck, causing the pump to run at maximum pressure.
