A fuel scavenge or "make-up" tank is an important addition to your 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. This round design also points the two inlet fittings at the side of the tank to de-aerate the fuel as it spins down the sides.
Install the tank between your fuel tank and your fuel injection pressure pump. Your feed or transfer pump moves fuel from the fuel tank to the scavenge tank. If the transfer pump starves due to fuel sloshing in the main tank, the 1 liter (1 quart) reserve volume of fuel inside the scavenge tank will continue to feed the pressure pump, preventing misfires as well as pump damage.
This aluminum tank has two barbed side inlets (one from the fuel tank, one return from the fuel rail) to accept 3/8" (10mm) ID rubber hose. The bottom outlet (to the injection pump) is barbed for 1/2" ID hose. A 3/8" barb fitting is provided on the top of the tank for a return line to the fuel tank. Mounting base measures 4 1/4" x 4 1/4". Tank body is 4" diameter x 5 1/2" tall.
