I purchased PCM's "Guide to Gas Pump Restoration" The biggest benefit, outside this forum, is that it is very detailed in, decals, signs, globes, and colors and image standards. As far as disconnecting the internals, it should be pretty basic. Again, I am not familiar with that pump, but it should be just some nuts & bolts. Be careful, those internal parts are heavy. My Southwest 45 was gutted so that I can install a small tv inside it for the shop or game room. Good luck & have fun.
