I am going to "borrow" the tank and pump from my 91 burban to use for the trip in a few weeks. I might go with one of the external ones before then if the money thing says I can do that. I will most likely go with one of the 60-70 dollar ones. I assume they have a warranty LOL. Thanks guys for the help.
I will use everything except the O2 sensors for now. I will add a set to my headers later but not in the cards right now.
