I would like to remove a plug at the bottom of my fuel tanks and install a valve for a future fuel polishing system. These tanks are on my Nordic Tug 42 and hold 300 gallons each. Right now, about 100 gallons remains in each tank. I could be completely off base, but I'm thinking that if I block all possible avenues for air to enter the tank when the plug is removed, that very little diesel will escape before I get the valve screwed in.
Am I asking for a disaster or will this work? I heard from something I read that hooking up a vacuum cleaner on the fuel fill opening to create a vacuum in the tank works so well that no diesel will escape from the tank. But I have a huge volume in the tank right now, so I wonder if this method is workable. I could fill the tanks to capacity as fuel is pretty cheap right now but then I may have a bigger disaster. I just don't know.
