A modified version of this is used in  hi HP engines where a 1 ltr. aluminum
canister (about the size of a tennis ball can) with a perforated membrane
(inside) about 3/4 from the top with 3 outlets on top; 1. Inlet from primary
tank (transfer) pump, 2. Outlet for return back to tank and 3. Inlet
from outlet of regulator at end of fuel rail. On the bottom of the
canister are two outlets. 1. About 1' up from bottom is an outlet that goes
to a booster pump and then to fuel rail. 2. On bottom is a drain valve for
sediment and water. All of this is located in engine bay (away from heat)
and assures that the only time fuel is returned to the fuel cell is when the
canister is completely full of fuel; thus eliminating the cavitation that is
being discussed here. /pc
