I thought this may be a good discussion. What is the best fuel sumping practice. I have a 235 and was taught to sump all 4 tanks from the belly and not to worry about the fuel valves on the bottom of the wings, they always seem to seep when I sump there anyhow. So this is what I have been doing for years. So two questions, what are your practices and are there different fuel sump valves that dont leak that I could replace my current ones with?
