fuel pump problems

[Jeremy_5]

Well I know this is not the right place to post but I always get better response here. Anyways I was working on my girlfriends dad 77, it wouldn't start, and I smelled gas in the oil, so I figured it was the fuel pump, well what I thought would be a 30min-1 hour job is still not finished.
My question is, when you crank the engine by hand to get the rod that actuates the pump farther up what way do you crank it, and should it stop when the engine is at TDC? It just kept turning and turning and the rod does not seem like it is up far enough. When I try to get the pump on it doesn't quite fit right. Any help would be greatly appreciated, I don't want to mess up his truck
