[Caprimaniac]

Now I'd need some advice: If the low rpm's were to be leaned out, and you still need enough fuel at 8000 rpm and when stepping on the throttle, would the F14 or F15 be the "best" one? Both have high holes only, as I understand, but the F14 has 8,2mm and F15 8 mm outer diameter.

If the walls of the tubes are exactly same thickness, then the F14 should have a larger fuel reservoir by larger inner diameter.

The theory of capillary forces acting inside the tubes have made me wonder after reading some: Passini say the larger inner diameter makes fuel move higher inside the tubes (if I remember correctly). My own experience is that the fluid will climb higher in a smaller diameter tube. Any thoughts on this?
