Where does the fuel pressure sensor located

If it would be on the fuel line under the hood just before the fuel injector rail. There may also be a fuel pressure regulator just before it. Look the part up online like you are buying one, and you will see a picture of what it looks like. It taps into the fuel line, has one vacuum hose and an electrical connector plugged into it. Buy a good name brand one or get the same as original. Cheap ones fail.
