My 2002 Ute never starts first turn of the key, and from reading online this seems to be a common problem with the fuel pressure regulators not holding pressure after priming.

The car has a new pump and fuel filter and the problem still persists, so i'm sure it is the regulator. My question is though, are these in the pump assembly in the tank or on the fuel rail in these cars, and where is the best place to get one from?

The fuel pressure regulator is in the tank.
