As Bart mentioned, IF it has been sitting a very long time, do NOT run it very long with the old gas in the tank. The varnish in that stuff can cause all sorts of problems if it gets into the engine. Been there, done that!
If it's been run fairly regularly the whole time, this may not be an issue, but wanted to bring it up.

Keep us posted on your progress. Looks like a nice truck.
