    The VR reg is a slightly different design but looks like it mounts very similarly (Mine had a philips head screw). I wouldn’t be surprised if it was interchangeable.

    The Haynes manual I have covers VN, VP, VQ, VR & VS, 1988 - 2000 yet only makes one mention of fuel pressure:

    240 - 260 KPa at idle
    280 - 320 KPa with engine off

    Which to me would suggest they are all pretty much the same?

    I wonder if it would be worth grabbing a VR one and seeing if it bolts up etc?

    Just pulled the VR fuel reg off the rail.
    Numbers on it below with a Bosch symbol.
    3.0bar. 469
    0280 160 529

    Looks just like your VS reg pics.

    Thanks for doing that, much appreciated.

    Looks to me like the only difference is the location of the vacuum line which is nothing really.

    Nowhere local sells these things so i’ll have to order one online.

    Just in case anyone else finds themselves in the same situation i’ll report back in about a week or so with my results.

    Cheers

    Didn't they increase the pressure slightly in the later engines, to get a few more kW on the glossy brochures?
