Check out Glenn's Performance for a tank with sump.Both good suggestions. I probably won't build the sump right away as I would only do that on a new tank. Considered using the hydromat when I was looking at in tank electric, but not sure I can get one in through the sender opening and positioned in a manner to make it worthwhile. I will make sure that the pick up is nice and low to the bottom of the tank and keep enough gas in it to try and avoid any starvation issues
