vent pipe for fresh water

I was always having a hard time holding up my 5-gal jeri can when filling my off-road Popup fresh water tank. Seems like it would take forever to empty the 5-gallons haha... We always like to camp off-grid with no city water hookups.

I finally rigged up a 12VDC water pump for boats from WALMART and now all I do is stick a tube down into the jeri can and it empties into the fresh water tank in a breeze now...
