It seems many of us have had difficulty in getting our livewell to properly prime. I have a solution that is not too expensive (less than $20) and super easy to do. Basically just attached a priming bulb to a 3" piece of hose (1" outer diameter 3/4" inner). This allows me to also fill the tank at the baitshop and not have everything leak out. It's awesome, works really well and you can leave it in the tank (or disconnect it if you want). What I did was I cut off the nipple end of the black valve and opened it up with my dremel. I have a 3/4" to 3/4" barbed nylon splicer at the base of the bulb (I pulled out the red nipple plug at one end and put the nylon coupler in its place. Finally, I connected the grey piece to the pump. The priming bulb and stainless steel clamps can be found at boating supply shops (don't pay more than $10 for this) and get the largest opening you can find. The hose, the nylon splicer and the grey piece were all at lowes or Home Depot. If you are overseas, try your local hardware shop. Here's one site selling the bulb cheap
