Hi all.
Looking to prove out a concept before I buy parts...
I have 2 15-gallon water tanks similar to these:
https://www.amazon.com/Gallon-Emerge.../dp/B07RG84S27
Tank does not have bottom fittings, only a single 2" diameter top bung-style opening.
I want to be able to place these tanks in the back of my truck bed, fill them with potable water, and then transfer the water into the fresh water tank on my 2608BS trailer.
With the tanks standing upright in the truck bed, the bottom of the tanks will be about 2 feet lower than the fresh water fill inlet on the trailer, so I'll need to pressure pump the water to the trailer.
Total hose run will be about 40-50'.
I want to purchase a 12V pump that will have an inlet and outlet hose. The inlet hose will need to be at least 6' and ideally more like 15'. The outlet hose will be 30+' and will go into the fresh water inlet.
My concerns with the pump... one, it has to be self priming. Two, I don't want so much pressure that it backs up at the trailer inlet and sprays back or puts too much load on the pump. Three, I don't want the cheapie pumps with the rubber impeller that wears out after an hour. Had too many of those in the past. Four, I want enough flow so I don't take an hour to transfer the water. Ideally, 3-5GPM. and five, I don't want to spend a lot of money on the pump. Ideally, the pump will be well under $100.
I looked at bilge pumps because they're cheap and really high flow. But I couldn't find anything that had an inlet hose; the one I thought might work, an Attwood Tsunami pump, may not because it's not self-priming. So I'm now looking at diaphragm pumps. This one caught my eye:

At $75, it's in the wheelhouse...
So the layout... 15' drinking quality hose, threaded onto pump inlet. Pump mounted on a small board, wired to a trailer hitch plug. 50' white RV hose threaded onto pump outlet, pumping water into fresh tank.
What am I missing?
