Agreed, and a pump to do it can be gotten at most any parts place like autozone, Napa, wherever.
They run about 40 bucks for one that will work fine for this.
It's basically a Mr Gasket foreign car generic inline and can be hung with the hose because they are so small and light.
They come with a plastic mounting housing that I cut off if not using it.
These also have an anti backflow valve built into the hose barb on the end.
