Group,
    Attached are links to the "Mallory" pressure isolat= or that is compatible with
alcohol/methanol to be placed between the "VDO" fuel pressure sender a= nd the
possible alcohol laced fuel that many of us in various parts of the co= untry have
had forced on us by our government men-ions...........Might be advisab= le since
Tracy has noted that "VDO" now says their senders are not to be used w= ith
alcohol/methanol.........FWIW
