Where should a fuel pressure regulator be installed?

In many cases, you can mount the regulator in a location to satisfy ease of installation, adjustment, and appearance. However, in the cases of high power applications, extra low fuel pressure systems, and high-g launches, it’s best to mount the regulator as close to the fuel delivery destination as possible.

Do I need an aftermarket fuel pressure regulator?

When you are running huge amounts of boost and the factory fuel pressure regulator can not keep up the 1:1 fuel pressure ratio. Therefore you will need an aftermarket fuel pressure regulator that can handle this high amount of boost pressure and keep up the 1:1 ratio.

What is a high pressure fuel regulator?

Say hello to the fuel pressure regulator. This small yet crucial part ensures that the amount of fuel sent via the fuel pump, and how much pressure it has, does not go higher than it should. If the fuel pressure is higher than what’s needed, the regulator stops the flow and returns the excess to the fuel tank.

Can you bypass a fuel pressure regulator?

With a bypass style regulator, fuel enters through the inlet port (A) and travels past a fuel bypass valve/fuel return line port (which governs fuel flow and pressure) (B) and then is distributed through an outlet port to the carburetor (C).

Can you mount a fuel pressure regulator on its side?

Fuel regulators can be mounted in any position. The tension sets the pressure.

What happens when a fuel pressure regulator goes bad?

A faulty fuel pressure regulator may cause the vehicle to experience misfires, a reduction in power and acceleration, and a drop in fuel efficiency. These symptoms can also be caused by a wide variety of other issues so having the vehicle properly diagnosed is highly recommended.

Which is the best aftermarket fuel pressure regulator?

Using the best aftermarket fuel pressure regulator with your carburetor ensures a safe and reliable fuel system performance for your engine. It will result in a better running, high-performance engine. Shop the full line of high performance Holley fuel pressure regulators available at Speedway Motors.

How to mount a Holley fuel pressure regulator?

Place the rubber gaskets (supplied) between the mounting bracket and motor housing and mount the pump in the vertical position (motor on top) using two 5/16” bolts. 4. Connect the fuel line from the tank to the fuel filter and the filter to the inlet port of the pump. Connect the carburetor delivery line to the outlet port of the pump.

Do you need a return line for a fuel regulator?

The lack of a return line helps decrease installation costs but it can also limit the performance capabilities. These regulators come in a variety of styles and typically regulate fuel pressures in the 1-9 psi range.

Where do you run the fuel regulator on a street strip?

In a street/strip application we recommend running the feed line directly to the carburetors fuel log then placing the regulator on the return line side of your fuel log. This allows the fuel to flow unrestricted to your carburetor, but still regulates the pressure and returns the unused fuel back into the gas tank.

What does a high pressure regulator do?

A water pressure regulator is a valve which controls the level of water pressure to ensure that it is effective and safe. In a multistory building, each floor may have a water pressure regulator in place, since higher levels of pressure are needed on high floors to successfully push the water up.

What are the symptoms of high fuel pressure?

Common symptoms of low fuel rail pressure are the following: Low power or engine power reduced message in driver information center (DIC) Change fuel filter message in driver information center (DIC) Poor transmission shifting operation. Increased smoke output. High exhaust gas temperatures (EGTs)

What does fuel volume regulator control circuit high mean?

One component in high pressure fuel systems is a high pressure fuel pump. It’s job is to increase the fuel pressure for the very high pressure needed at the fuel rail for the injectors. These high pressure fuel pumps have a low pressure side and high pressure side, and a fuel volume regulator which controls the pressure.

Is the fuel pressure regulator an engine job?

The fuel pressure regulator is part of the engine’s fuel supply system. The regulator is completely separate from any “mechanical” component of the engine. The purpose of this regulator is simply to maintain a specified pressure on the fuel supplied to the fuel injectors.
