I'm wanting to clean out the gas tank in my boat. Right now I'm running around with a 6 gal tank topside. I wanna get the belly tank operational. I'm thinking of popping the sending unit off, and running a borescope or something of that nature inside the tank so I can take a look and see if its salvageable/cleanable. If it is, I was going to suck out any residual fuel, and once it dries, take another look. Do you guys have any experience doing this kind of stuff? This is the first time I'm attempting to clean one "in boat". Thanks in advance fellas.
