Fuel pressurization as well as fuel draw are non-issues. I have the tank right behind the firewall and lines are only a few inches long. Engine idles, transitions, and runs okay at top end but , as I stated, needle adjustment range is minimal and a pump would not affect this. Am pretty good on engines and tuning and believe the 1.08 carb has a much more coarse adjustment, may have to do with needle taper....haven't checked.
