How to buy a good quality fuel pressure regulator

Fuel pressure regulators come in all shapes, styles, and capacities, from fuel injected to carbureted cars, diesel engines, and E-85 engines. The fuel pressure regulator works with the fuel injection system to direct fuel into the engine to achieve efficient combustion.

The fuel pressure regulator must be in optimum working condition to ensure accurate fuel delivery to the engine and is usually located on the fuel rail or near the injectors or injector block; although there are built-in controls. If you have a vehicle with a returnless fuel system, the fuel pressure regulator will be built into the fuel pump assembly.

• Typically, a fuel pressure regulator has an internal that uses a spring and a diaphragm against which the spring presses. The pressure on the spring is set by the manufacturer to the optimum pressure so that the fuel injectors operate at maximum efficiency.

• A valve attached to the diaphragm opens when the pressure is too high to allow fuel to flow into the return line, preventing the fuel injectors from getting too high pressure.

• Fuel pressure regulators are very reliable technical items and rarely need to be replaced, however, you may notice a drop in pressure in the fuel system, starting problems or poor handling when your car is idling because the engine is not getting the fuel it needs. to run smoothly.

• Aftermarket fuel pressure regulators should be just as good as OEM (original equipment manufacturer) parts.

• Depending on your vehicle's engine layout, you may need to replace the entire fuel delivery unit, not just the fuel pressure regulator.

• In-tank and in-line fuel regulators are available. If you're not sure what part your vehicle needs, see a qualified mechanic to find out more and make sure you're getting the correct part.

While they don't often fail when you have problems with your fuel regulator, it's important to fix them quickly by replacing the part.
