Integration in the vehicle's supply line or return line

NOTE:
– Fuel extraction must be almost pressureless.
– Where fuel is drawn from the return line, you must ensure
that this line is not blocked by check valves. Also make
sure that the return line reaches to the bottom of the fuel
tank.
– A zero flow must never occur in the vehicle system as a
result of fuel extraction.
– For extraction from the swirl pot, ensure that the swirl pot
is not completely empty.
