Is it taking in air when it is running (poor running or lumpy idle speed) ? , or is it leaking fuel out ?

I do not think the seals are brilliant in these pumps, but if its not taking air in and not leaking fuel out I'd not be concerned at a lack of vaccum depression, it may be that the vacuum is strong enough to get past the seals.

I think we need to know what the 'problem' is rather than the reading...
