I never run onboard fuel pump or onboard glow with any of my 4-strokes. Those just add weight and are extra things to worry about. I only fly with pumped OS 4-strokes and YS 4-strokes, and since YS 4-strokes are supercharged and pressurize the fuel tank, there is no need or desire to use onboard fuel pump.

By the way, I find YS much more easier to tune than both OS and Saito. Once my needles are set, I don't touch them again. Of course, your mileage might varry. It took me 30 seconds to tune that YS 110 in the video given above after two tanks of fuel on the bench. Good luck trying to do the same to any other 4-strokes.
