Wheres the fuel pressure regulator located on a 99 3.0L. Any body got any clue?

Thanks,

It is in the tank, part of the fuel pump assembly.

 

^ yup pretty sure its in the pump

 

On my 99 3.0L (FFV) the FPR is located on the passenger's side fuel rail, just behind the schrader valve. Look down just in front of the coilpack.

 

AFAIK, 98+ Rangers are returnless fuel, meaning that there is a single fuel line up to the fuel rail and no return line back to the tank. With the returnless system, the pressure regulation is done in the tank.

The return type system used in earlier years regulates pressure at the fuel rail by dumping the excess back to the tank through the second fuel line (return line).

If there is a single fuel line to the engine, then the device on the rail is not the fuel pressure regulator. There a fuel pulse damper on the fuel rail of the returnless trucks that looks very much like the fuel pressure regulator used on the return fuel trucks.

 

Thanks Bob, I'll have to see if there is a return line, but this "device" looks like a FPR, with a vacuum line going to it.

 

The FPD also has a vacuum line to it and it does look like a FPR. It's possible that the FFV Rangers are a special case and that they retained the return system for some reason when the rest of the Ranger line went returnless - don't know. I'd be interested to hear if your FFV has a return line.
