For his sake and mine, which way does the oil pump need to be turned, clockwise or counter clockwise?
Back to your plans:
Call the local radiator shops and see if they can clean up your fuel tank. (Although I think buying a new tank is cheaper).
Buy a Harbor Freight tube bender. I got mine from ebay.com. You can get Poly Armor fuel line from NAPA. You'll also need a tube cutter, Lowe's has those for cutting copper pipe.
I used the screw down hose clamps over the spring kind.
You'll also need a flare kit. I used a Craftsman model from Sears.
To flare your lines you'll also need a bench vise. I bubble flared all my ends.
I also put in a manual fuel shut off valve behind the seat. I messed up and put it down too low, so I'll have to redo that.
As you can see, this isn't going to be a quick or cheap job but if you take your time and get as much info before you buy or do anything, you'll be OK in the long run.
We want to help you!
*In fact, you and I should hang out sometime: both of our trucks came from 1972 and our dads.
