I have recently received a newer,bugger sump for my 120 my question is.Can I take both of my 1"drain lines and put them into a 2"line and then run that to my sump that is located in my fish room behind my tank?Any help would be great

Yes you could but I probably wouldn't. You may want to put the two returns in different parts of the sump. IMHO you don't want anything restricting the gravitational flow draining the main display. Especially if you have no additional backup overflow pipe. But I can't think of anything that would be a problem if you combined them as long as you somehow screen the return before it goes into the piping.
