Abstract
Fuel for an engine (2) is supplied from a first fuel tank (5) and return fuel from the engine is gathered in a second fuel tank (6) for resupply to the engine. The second fuel tank (6) constitutes a fuel tank which is connected to and fillable from the first fuel tank (5) and from which the engine received all its fuel. The engine is provided via a fuel pump (4) with fuel from the second fuel tank (6) which is itself supplied via another fuel pump (9) with fuel from the first fuel tank (5). The second fuel tank (6) is provided with fuel venting.

A method of fuel transfer in combustion engines whereby fuel from a first fuel tank (5) is supplied to the engine (2) and return fuel from the engine is gathered in a second fuel tank (6) for resupply to the engine, characterised in that fuel from the first fuel tank (5) is supplied to the engine via the second fuel tank (6) so that the engine is supplied with fuel from the second fuel tank only.
An arrangement for fuel transfer whereby between an engine (2) and a first fuel tank (5), which is the main tank, there is a second fuel tank (6) to receive return fuel via a return line (10) from the engine, the second fuel tank (6) is also connected to the engine's fuel inlet and there is at least one fuel pump (4) for conveying fuel to the engine, characterised in that the second fuel tank (6) constitutes a fuel tank which is connected to and fillable from the first fuel tank (5) and from which the engine receives all its fuel, and that between the engine (2) and the second fuel tank (6) there is a fuel pump (4).
