obp Fuel Scavenge Tanks
A fuel scavenge or "make-up" tank is an important part of a racing fuel injection system. It works like a dry sump oil tank, holding a relatively tall, narrow column of fuel over the outlet fitting. This makes it less likely that the fuel pump will starve due to fuel slosh when cornering or braking.
Install the tank between your fuel cell and your fuel injection pressure pump. Your feed or transfer pump (high-volume, low pressure) moves fuel from the fuel cell to the tank. If the transfer pump starves due to fuel sloshing in the cell, the reserve volume of fuel inside the tank will continue to feed the pressure pump, preventing misfires as well as pump damage.
