need some help. think i killed my clutch....

Hey yall, I traded my old blue k30 for a diesel k20 hd. Big mistake on my part, but nvm that. I just wanted to ask a few quick questions.

Where is the fuel pump located on my 1986 k20 hd diesel?
How hard is it to do a full body swap?
And a quick story to sum up this question, when i got the truck the guy said if I needed to move it before i got time to change out the fuel pump. Well just get a little speed and dump the clutch, now whether i have it in gear or not I get no resistance. And it just makes a loud almost humming noise as if its stuck in a low gear? Its a brand new clutch too, any ideas? And also, since im about 98% sure its gone. What parts would i need to fix it? And could i use the clutch from a 1977 k20 350 gas?

Thanks for everything.
