Volumetric metering equipment comprising an injector mounting block by which injectors of a multi-line fuel injection system can be mounted on the equipment. A measuring device is in communication with the mounting block via a feed line to allow test fluid to pass from the injectors to the measuring device when the equipment is in use. The measuring device is constructed to provide signals which are indicative of the amount of test fluid received by the device. Point-of-injection detectors are arranged adjacent to the injectors for determining which of the signals relate to an individual injection.
