How To Choose a Fuel Pressure Regulator

Choosing the best fuel pressure regulator for your car or truck can be difficult, but very important when trying to get the best performance. If an engine is going to output a lot of power, then it’s going to need a lot of available fuel to do so.

This can place a lot of demand on various systems, where the need to get fuel to the right areas with an appropriate amount of pressure becomes more important.

A good fuel pressure regulator will regulate pressure back to a vehicle’s fuel tank or prevent further buildup while in use. There are many types of regulators for an engine, each with its own advantages and disadvantages. Depending on if your vehicle has a carbureted system or EFI system, you’ll want to go with one option or the other.

Want to know how to choose the right fuel pressure regulator for your engine? We’ll make it easier for you with this guide on what you should keep in mind. Getting the best results for your engine results from having good information at your disposal.

Types of Fuel Pressure Regulators

You can find a few different types of fuel pressure regulators in various places, each with its own perks and cons for installing into an engine. The types available are deadhead-style regulators, bypass regulators, and return-style regulators.

Bypass regulators are also known as return style. They bleed out extra pressure that builds up back to the fuel tank when operating. These types of regulators are usually adjustable in many ways and are recommended when an engine is using a high-pressure pump.

Deadhead-style regulators control pressure with no return line. Unlike return or bypass, a deadhead will restrict the fuel flow when pressure exceeds a set amount. This lowers the fuel that the system sees afterward.

Advantages and Disadvantages of Pressure Regulators

Depending on the type of fuel regulator you have installed, you’ll have different effects on your engine performance. Bypass fuel regulators always have fuel flowing through the system.

This lets you keep the temperature within operating conditions and allows the pumps to work at maximum efficiency.

Yet, having a return line makes the system a bit more complex and can be difficult to work with if something goes wrong.

Having a deadhead regulator allows for only one line installed, and can be used in a system that has one pump but many regulators installed with it. At the same time, deadhead regulators also have an increased fuel temperature and put more strain on the fuel pump with more pressure. These types of regulators also cannot be used with more EFI systems and pumps.

Choosing the Right Fuel Pressure Regulator

With a little help from our brief guide, you should have all the tools you need to pick the right fuel pressure regulator for your engine. You’ll get the best performance you need when you have the right fuel regulator to help give you the necessary power from your vehicle.
