Well, it looks like I need a few new bits.

 

Yeah, if I were to guess, I'm thinking new fuel pump and hanger, filler tube, maybe even the fuel tank, if you can't get that one chemically stripped and sealed. Definitely new fuel filter, maybe pulsation damper, injectors, and pressure regulator. That rust flows all through fuel systems, clogging up the most unexpected parts...

I'm sure there's a lot more. You've got a project started, no doubt. I wish you the best of luck with it!
