I have changed the fuel filters on my catalina 310 numerous times. I am familiar with how to do it, but have a new issue. Normally I close both valves on the tank one would be for the supply to the engine and the other for the return. Since the engine is gravity fed from the fuel tank if the valve or valves are not closed fuel would continue to run if you did not close the valve or valves. My question is when looking at the tank, looking toward the stern there are two valves one to the right of the fuel sender and one to the left. The one to the right is easy to get to and turns very easily, the one to the left of the sender is harder to get to and does not turn very easily in fact I am afraid I will break the handle off if I continue to turn it off. The questions are do you have to turn off the return valve and is it the one to the left of the tank.
Thanks for any input,
