what's the fuel pressure of the 2003 vvt engine?
 

I got an adjustable fuel pressure regulator a while back and I finally got around to putting it in. Now I can't seem to find what the fuel prssure should be. Any help?

Per the factory manual, within the range of 53-61 PSI under all load conditions (from idle to WOT.)

I believe the nominal pressure is 400 kPa, which is around 58 PSI.

Thank you kind sir. You have saved both me and my engine loads of horror lol

Returnless fuel system.

Man with large hat.

Is it an in tank adjustable fpr? I'm curious to see how that's working on a return less system. Enlighten me. :)

Using the evap line as a line back to the tank with it moved at the tank to go into the unused return line port on the tank and run a custom tune to compensate for the fact that your fuel pressure now changes based on manifold vacuum rather than stays static.

I have the fpr in a 94 chassis that has a full 2003 engine, hanress, and ecu. Still has the na gas tank and lines

I don't quite fallow but a beautiful statement none the less.
