    Fuel Pressure Regulator

    2001 Mercury 200 EFI
    Serial# OT324372

    Can anyone tell me what the seal looks like that goes in between the Fuel Pressure Regulator and the VST body. I have a leak there and don’t see that you can buy a seal only. Thanks for any help.

    I have an oring between the pressure regulator and the brass fitting. Then found a plastic flat washer on the the bottom side of the pressure regulator where it is held down over the nipple that is on the top of the vst casing hat.

    Only sold as part of the regulator kit. I recall having matched one up previously with a generic (Viton or Nitrile) o-ring.

    Do you have a picture of what the oring looks like. When I took this one apart it had a plastic washer. Thanks

    No- but it's just an o-ring. Round, fits outside the shoulder on the VST, and INSIDE the shoulder on the pressure regulator, while standing proud/tall enough to seal between the two.
