The fuel pressure regulator is a part of most modern vehicles’ fuel system. The job of the regulator is to regulate the flow of fuel to the engine based on the response from the driver. Many cars with ‘economy’ and ‘sports’ modes use a fuel pressure regulator to increase or lower the supply of fuel. Take for instance that when a car is in sports mode, the engine is revved higher and requires more fuel, so the regulator will open the valve wider to allow for more fuel to flow. The opposite happens in economy mode. Though a bad regulator can ruin the overall performance of the vehicle.
Just like anything else mechanical, a fuel pressure regulator switch can fail. If the regulator itself fails or malfunctions your car will feel sluggish. Also, if you have a problem with your fuel regulator, you may notice thick black smoke coming from the tailpipe, experience cold start stalling or notice your usual mileage dropping. These are just some of the signs to look out for if you suspect something may be wrong with your fuel pressure regulator switch or the regulator itself.
It goes without saying that there are various types of fuel pressure regulators. Each type of car uses its own type of regulator based on the ECU’s programming and the modes of that particular vehicle. So, it's important always to replace an existing part with one that’s especially meant for it.
