Its all completely circumstantial. Using random numbers, say you have 300lph of fuel available before pressure drops, and your engine is consuming 250lph of it, then this means you can "afford" a leak of 50lph before pressure begins to drop. Your fuel consumption with a centrifugal supercharger will climb to it's peak at redline. So the closer to redline you get, the less you can lose to a system leak before its causing an immediate problem.

So you can definitely leak enough fuel to tax your fuel system to the point of running the engine lean. Only you saw how much was leaking, so none of us can say with absolute certainty whether its enough to cause a lean condition. But I have only ever heard of these gauges dripping or oozing a little, I have not yet heard of one really letting it go in a significant way, or basically bursting mid pull.

If it is truly leaking a whole ton, I would like to get it back to the manufacturer.
