FIELD: engine devices and pumps.
SUBSTANCE: two-chamber fuel tank comprises a fuel pump (4) with a bypass valve (5) which is installed in the main chamber (2). An additional chamber (3) communicates with the chamber (2) via a siphon (6). A jet pump (7) fills the siphon (6) with the fuel when it is supplied from the valve (5). A pump (7) is equipped with a drain valve (8). The valve (8) opens direct passage of fuel from the siphon (6) to the chamber (2) when the fuel feed is stopped from the valve (5) to the pump (7). A control inlet of the valve (8) communicates with the valve (5) outlet.
EFFECT: increasing reliability of feeding fuel from the two-chamber fuel tank to the engine by accelerating the fuel transfer from the additional chamber into the main chamber.
