    Fuel pressure regulator

    My 1986 RR V8 EFI runs quite well, but always seems a bit breathless over about 3000rpm.

    I've started to think fuel pressure regulator because it has zero pressure retained after just a couple of minutes of engine off.

    The RPI site recommends a rising rate fuel pressure regulator as an upgrade for the V8's and I was wondering if anyone has experience with RRFPR and where can I get one locally.

    Try clamping off the return line temporarily just to see if it improves over 3000rpm & with the engine off, just to isolate the regulator.
    Can't help with the RRFPR.
