Too answer your question, if your are going to put it in the house I would gut the pump from bottom. You won't hurt value ,as most collecters do this. JM2C worth,others may tell you different.
Thanks. I found the FAQ on this page last night and read the same. That's what I was mainly worried about decreasing the value. Good to know that it won't. Should make it a little lighter!
Anyone know how much one weighs not gutted and how much gutted? I unloaded out of truck by myself somehow. It was heavy!!!
