How hard is it to take the sender out having the tank on? Or should I drop the tank?
Personally I have never took a sending unit out of the tank. But I would imagine it would much easier to drop the take rather than removing it with it mounted.
And if you may, explain what to do to take the sender out...and what is this "sock" I should replace?
The sock is a filter screen that goes on the intake end of the sending unit pipe. Keeps trash out of the lines, carb, etc.. Sometimes all they need is a good cleaning but I would replace mine if it was me.
while cleaning everything up...how do you have the tank "boiled" out?
When you want the the tank clean on the inside you can take it to a radiator shop and they boil it out so the tank will be clean on the inside.
