You may think about keeping a couple extra fuel filters.
So very true. A couple of years ago, I bought a 74 k10 for a parts truck for the one I am rebuilding. She was in no way solid, but I needed to drive from California to Idaho and tow back a boat.
I did a tune up, checked everything over and fixed what I thought would not make it and away I went. Only problem she gave me was as Engineer said, I ended up replacing the fuel filter for the first 3 fill ups because they were getting plugged, after the 4th filter, it was good to go.
