Location of fuel storage tanks and their capacities. Although there is a trade-off between downforce and drag on the short track cars, reducing drag is not critical because the engine power is not restricted and the speeds are generally lower. You must run a filter on the inlet of every pump to protect it. Kinsler continued, Some electric fuel pumps are extremely well made, and a few brands offer variable output flow controlled by the ECU, which can be very handy to obtain an exact fuel map.
