The fuel pressure sensor senses the amount of fuel in the fuel rail by reading the internal pressure of the rail. It can then send an electronic message to the PCM telling it precisely how much fuel needs to be released into the engine.

Is a fuel pressure regulator the same as a fuel pressure sensor?

On the newer models, the fuel pressure sensor is used to regulate the fuel pump and the regulator is used to dampen the changes in pressure level. On older models, the fuel pump is running at one level and the regulator uses the intake vacuum to dampen and retain pressure.

Is fuel pressure sensor necessary?

Used to ensure steady fuel supply, a fuel pressure regulator is needed to keep your car going. Even if there are dramatic fuel demand changes, your fuel pressure regulator will make sure the fuel is flowing properly. There are two sides to the fuel injector.

Where do you put a fuel pressure sensor?

It uses a hose plumbed from the fuel system to the back of the gauge. For safety, you MUST mount the gauge outside the driver’s compartment. Bringing fuel into the driver’s compartment is a major fire hazard and safety risk. Most people mount the gauge just in front of the windshield, where the driver can still see it.
