    VFR400 Fuel Problem

    Hi All,

    The VFR (NC30, 1991) isn't getting any fuel into the carbys. The vacuum hose is connected, however it doesn't have any vacuum on it. Fuel flows fine (all over the garage floor) when vacuum is applied manually. What does this mean? How do I go about fixing it?

    Cheers

    Gary

    To what? From the tap to the inlet manifold/or carb?
    Don't you look at my accountant.

    The vacum hose you talk about(leads to switch - fuel on and off) could have a hole or crack in it. Take it off blow into it to check. Maybe a bucket of water will help to see if there is a leak.
    Check the attachment on the intake also if it is seated properly and does it also create a vacum
