How much pressure would you like, Cane? I think there are some great bilge pumps out there that really pump tons of water, but they will not develop much pressure. They are also restricted to less than 10' of head.

Head is calculated as not only the vertical lift, but also loss due to friction. For every 10' of hose you add on the horizontal, you will add 1' of head.

If you need pressure, then I would look at a simple shallow well pump.

Gould makes a nice little package that can deliver good pressure. Its a complete package, but might be more money than you want to spend.

Its the Gould BF03s. It'll run about 600.00.

I had a 12 volt wash down pump that had 40psi. Bout 100 bucks 10 years ago. It had 3 chamber pump whatever that was. Some R/Vs have them I believe.
