I didn't find any videos on youtube about this pump so I made this.
It cost me 9$ at a local hardware shop.
It isn't intended to be used for long on 12V as it overheats quickly. On 4v it's fine.
I should also add a warning to not try to open the motor assembly. The metal part is the actual motor and getting it off and on again is really hard.
