Fuel Pressure Regulator
The right fuel pressure of your engine doesn't seem to be a pressing issue, unless of course your vehicle's own fuel pressure regulator is defective. That's because this small automotive part is meant to maintain the fuel pressure at a constant level, above the intake manifold pressure.
Located near the fuel pressure rail, this regulator checks whether or not the fuel pump ensures the correct fuel volume. Lastly, it prevents the dreaded carburetor flooding, which can really give you a headache. Many fuel pressure regulator brands are out there, though you need to remember a few things to get the right one. First, the regulator should be made of durable materials that last longer and prevent corrosion. Also, it should have a diaphragm that resists harmful fuel additives like gas, alcohol, and even methanol. In addition, it should leave no room for chattering and bouncing, which can be detrimental to fuel flow.
At the end of the day, you want to get better fuel flow from your ride's high-pressure fuel pump and to do that, you need reliable fuel pressure regulators. You can choose a regular or an adjustable fuel regulator. But keep in mind that your car's performance still depends on how you take care of it and maintain each of its components.
