Simply Auto MSYP1 Multi Use Siphon Transfer PumpThere is an old way of siphoning fuel and it involves a length of hose and a mouthful of petrol. Simply Auto Siphon Transfer Pump makes liquid transfer a whole lot easier. Squeeze the bulb three or four times to prime it, and once the liquid is moving gravity keeps it going without further pumping.It handles more than fuel too: water out of a fish tank or a flooded footwell, coolant and antifreeze during a system flush, lubricating oils, and general fluid transfer between containers. The plastic is oil and acid resistant, which is what allows it to be used on petrol and diesel rather than water alone.Fitted to the intake hose, the dipstick tube feeds down the dipstick hole to the bottom of the sump, allowing for an oil change without jacking the car up or going near the sump plug. Useful on cars with awkward access, and on boat and mower engines where there is no drain plug at all.It also works as an air pump. The air pressure hose fits the discharge nozzle and the inflation adaptors cover dinghies, airbeds, toys, beach balls and other inflatables, so it's worth taking on road trips, camping excursions and holidays as well as keeping in the garage.Everything comes in the box: hoses, hose connectors, inflation adaptors, dipstick tube and air pressure hose.Two things worth remembering: The discharge hose has to sit lower than the intake hose or the siphon will not run. And after moving petrol, diesel or oil, flush the pump through before it goes back in storage.
