Pinhole fuel leak

[(RIP) Mark H]

During a major service I discovered a pinhole fuel leak where the plastic fuel regulator pipework meets the rubber tank outlet tubes, a tiny jet of fuel could be seen from a pinhole on the plastic tube when ignition on
It's fixed now, but just wondering that the slight loss of fuel pressure may have leaned the mixture? The leak was upstream of the fuel regulator so possibly there was ample pressure, The plugs did look a bit lean though?

No leaning at all from the leak, the normal excess return to the tank is 2 litres a minute.
Stock fueling is lean.
