The peace of mind for me is when I take a dump in the middle of the channel, and need a prime to get the engine going fast again before I get mowed to pieces. Or if I run dry and need to get the motor going again before I get mowed down. I plan on putting a reserve line back on, so if I run it out in the middle of the channel, and switch to reserve, I want to get the motor start as fast as possible to get out of the way. I don't see how the hose connecting to the T can cause an air leak, I mean I see how it could, but I don't see how it is any different than where the hose hook up to the carb, or where the hose hooks to the fuel pickup, they can all develope leaks, thats why you check your lines every so often so you know when they are wearing and if there is a problem somewhere. Inspecting the fuel system should be part of routine maintenance for everyone anyways after you pull the ski out of the water.
