Abstract
A fuel supply system for an internal combustion engine includes a fuel pump which draws fuel from a supply tank. A subsidiary fuel tank receives fuel from the supply by way of a conduit which incorporates a one way valve. The inlet of the pump is connected to a pipe which extends to adjacent the lower wall of the subsidiary tank. The subsidiary tank can be pressurized with air to force fuel towards the pump and a safety valve is fitted to the subsidiary tank to limit the pressure build up therein.
