1. Yes you can use your original tank.

2. No you do not need a single tube sending unit.

3. Yes only 1 line and either 5/16 or 3/8 line depending on what engine you have you can use your line that is feeding your fuel pump now, unless it is rusted and has holes in it.

4. I am using my orginal cap and I have had no issues, because it is a vented system already, that is what the extra line is going up into the cab.

5. You can but why worry about it? You can't see it and mine never smells the cab up, so I don't really see the need to pull it out.

Hope this helps!!
