A very handy and versatile unit for sucking oils and fluids from equipment.
Includes a 1L reservoir for collection of extracted fluid, this kit can be used for taking oil samples. 

This unit can be used with or without the collection reservoir connected. If used without, a tube can be connected to the hose tail where the reservoir attaches, and can be run to a larger container.
For applications such as oil changes, this unit can suck the waste oil from the engine/gearbox etc out to a container, and after flushing the pump the tubes can be switched around to suck new oil from a new pack and pump it back to the engine or gearbox.
There are many potential fluid suction or transfer applications where this handy manual fluid pump will make the job so much easier.
