I'd recommend the following. They are less than half the size, and cost half as much. I use two of them in my KR (500 hours ) and one or the other or both run continuously. My pumps are in the cockpit and the fuel in the outer wing panels. The pumps will self prime within seconds and appear to have internal check valves. Before I installed them I hooked them head to head and could not pump backwards through them so I eliminated the in line check valves.
