Internal fuel supply system for vehicle saddle style fuel tank having two chambers separated by a dome in the tank floor

摘要

This saddle style fuel tank has two chambers (11,12) separated by a dome (13) in the tank floor (14) and is provided with two injector pumps (8,9) situated close to the tank floor, one in each chamber. In one of the chambers is a fuel baffle chamber (2), which is supplied with fuel by the injection pumps. Fuel is supplied to the baffle chamber by the second injector pump (9) through a supply tube (6), whilst the two pumps are connected by a drive pipe (7). So that the drive pipe does not act as a siphon, a non-return valve is fitted in the pipe or in one of the injector pumps.
