Two solutions!
Solution #1, Get an outboard motor gas primer bulb at walmart(around$4) and put it in your intake hose. Make sure the arrow is poiinting up, to the tank!
Solution 2, Not pleasant, but it works! Put a length of clear vinyl hose(Home Depot) over the end of your attwood pump spigot in the tank. Make it about one and a half feet long. Start your pump and suck on the end of this vinyl tube. As soon as you get water in the tube , put the end down in your bait tank, it'll keep on pumping!
I use a 6 volt 12 amp-hour battery on my tank, it provides a correct flow. But if you use the outboard motor primer bulb, hook up your 12 volt battery with correct polarity. It should be ok, because the internal diameter of the bulb is 3/8 of an inch. This restricts the flow! Here's a pic of my tank. Notice there is no outlet hose. The water escapes thru the holes I've drilled in the tank horizontally at the desired depth! It runs out the other scupper! First pic has a fat intake hose for my fish n dive! Pic 2 has a smaller intake hose for my Pro 2 Tandem(Smaller scuppers!) !
Some people put a mesh garlic sack over the intake as a filter. Others stuff a small piece of a scotchbrite pad in the end. The bottom line is to gradually debug your bait tank until it works for you!
