” This Suphon pump is available online at many places. it can be had for £6 to £10 including the shipping. It is a very cheap Chinese built product for syphoning liquids like petrol, diesel, water, and oils

It is a very inexpensive tool and you should understand that it is not built the best, but it can do a decent job and provide good value. The pipes do not fit well into the pump body and need to be shoved in rather tightly. The first time warm the pipes in hot water seems to make it a little easier. Afterward to insure no leaks, it could help by sealing them with tape around the connections.
