SF_SN888KE,

Some welders would want it cleaned before welding others may not. it sounds like you are looking into doing quite a bit of work to it so it might be better to have it cleaned first. That is what I would do for safteys sake. Who ever you choose to have it done by, make sure that they have welded on gas tanks before. It is not that big of a deal if it is done correctly.
