What is a Fuel Pressure Regulator?

A fuel pressure regulator is used to help keep your fuel supplies balanced and controlled, no matter the drastic changes on how your car needs fuel.

It helps the fuel injector, which has one side that is under pressure, and another which has air from a turbo or compressor. It's best to keep the pressure from the fuel rail and compressor balanced, to avoid the fuel from leaking and wasting your car's fuel.

The fuel pressure regulator is usually located in the fuel tank or on the fuel rail. It has a diaphragm to control the bypass valve that lets fuel flow through the engine. When there is pressure on the regulator, the diaphragm will be forced down, lessening the amount of fuel put into your engine.

Functions and Importance of a Fuel Pressure Regulator

A fuel pressure regulator is very important in order to regulate the flow of fuel into your engine. Not only will it save up on fuel, but your car will be in running shape without it getting any damage from having too much or not enough fuel.

Housing

A fuel pressure regulator must be made out of the durable and premium materials (such as steel) to avoid corrosion or damage to it. With the fuel pressure regulator withstanding any form of rust or damage, it will be able to efficiently put pressure to balance fuel levels for years.

Type

You can choose between fixed-rate or adjustable, where you can manually adjust the pressure with the latter. If you are unsure about your car's fuel system, it's best to go for a fixed-rate fuel pressure generator.

Quality

If you will be replacing your OEM (original equipment manufacturer) fuel pressure regulator, then you should find one that is recommended by the manufacturers, and one that will perform as good as the original part you replaced.

How to Replace a Fuel Pressure Regulator

You will know if your fuel pressure regulator will need replacing when:

Black Spark Plugs

Check the end of the spark plugs. If it looks sooty, then check the others. It's best to replace both regulator and plugs if they are in bad condition.

Poor Engine Performance

If you feel like the engine isn't running as smooth as it should, then change your oil filter and then check the pressure regulator. Having difficulty when starting your engine is also another sign of a faulty fuel pressure regulator.

Black Smoke From Tail Pipe

This is a sure sign that you have a bad fuel pressure regulator, as smoke should usually be white or gray.

Dipstick Smells Like Gasoline

Get the oil dipstick out and smell it. If you smell fuel, it may be due to gasoline leaking.

Gasoline Dripping From Tail Pipe

This is caused by an overflowing tank or a bad fuel pressure generator.

Stalling Engine

There should never be an engine stalling, and it might be the result of a faulty fuel pressure generator.

There's Gasoline in Vacuum Hose

Check your vacuum hose and check if there is gas in the line. Gas dripping when the switch is on is also a bad sign.

While you can have a mechanic repair it, it's better to get a brand new one in order to lessen these chances of it breaking again.
