I've got a project F3 that I'm workin' on right now. The fuel pump is definitely not putting anything out so I did a straight gravity feed to the carbs, still kept the inline filter on there. The power is still strong up until about 8-9k RPM then it seems to drop off a bit.

Albeit, I still have a lot of work to do and this bike sat for a long time, but even without the fuel pump the bike still gets up to about 60mph pretty quick, and I'm really just limited by the length of my dead end street I'm testing on.

Should be fine then, just keep the tank topped off because with a direct line, as the fuel level goes down the fuel pressure will drop when your tank gets low I think.
