  Its rusty, i cant read it. I already putted it back, i need the car :-)

  I Bought this car for parts but it was clean and nice inside and bad tranny. I bought a scrap 5000TQ and put the tranny on it.
  The guy was tired of his car and broken his tranny cause he never checked the oil level :-(.
  He accidented on the fuel distr. side. THe engine was already run rought when i buy it.
  The guys who fixed it after the acident did not do a good job. The steel hoses were sqeezed and connectors were oxidated..... i changed some connectors , clean others, added and changed some hoses and hoses clamps.

  I always run the car at 60-65 psi, the engine never runs good since i have it, 1 year ago. I noticed the problem only in winter. 

  Here in Quebec everything in steel, rust :-).

  The adj. is for residual pressure but it affect the system pressure, when i look at the pic of the fuel reg at http://www.sjmautotechnik.com/trouble_shooting/ficis.html

  I ll call him.
  I ask in couple Audi Forum for part number.

    Very interesting!
    Can you find the part number on the fuel pressure regulator? We can look up
    the part number and see where it is supposed to be used.

    Give Chris a call at Force 5. He probably has these all over the place. I
    dont think there is much demand for fuel pressure regulators. Its a simple
    device - spring and metal valve. Not much to go wrong there. And its
    protected from water and spray as it sits alongside the fuel distributor, so
    these things dont rust out.
    If you beg nice, Chris may give you his bare bottom, "selling it for less
    than what it cost me" price.  :-)

    What is the history of this car? How long were you riding around with the 60
    PSI regulator? Did you have peculiar symptoms since you owned the car?

    In a previous post, or in that pix that you sent me, you said that there is
    an adjustment on the pressure regulator? Did you try adjusting that to see
    if you can get the pressure up to 90PSI?
    Oh wait, you said residual pressure adjuster. How do you know that?

      Car: Audi 100Q 1989
      CIS-3
      Problem: Low fuel system pressure .
      Fuel pump tested:OK
      Fuel syst pressure:62 psi approx.

      I did made an air pressure test on my Fuel Pressure Regulator.
      I putted an air regulator to the fuel inlet of the FPR with 0 to xx psi.
    The regulator open at 60 psi instead of 90psi.

      The car has been accidented before i got it so maybe they put the wrong
    regulator from another car...VW !! other Audi !!, i dont know.

      When the FPR in place i read 62 psi system pressure but with the air it
    only goes to 60. Anyway its far from 90psi.
      60 psi it s precise pressure, it might not be a 90psi regulator. They
    might tried couple regulators until they found one that works, even at the
    wrong pressure.

      I tried to put 90 psi short  shoots to make a dust come out..... from
    inlet , return line. But nothing changed , the FPR still open at exactly
    60psi !!
