I'd say for fuel line, if talking pump to carb, go see if Napa or someone can get you a stock replacement. If they can't, I'd be surprised. LMC probably has them. Just not worth the hassle of trying to cobble something together, and personally I won't mess with rubber up there. I know lots have no problems, personal preference is not to.
Front center angled to drivers side and down is EVAP. Lower front large one is PCV, from there, all educated guesses...I'd suspect front upper left small one is vac advance, front lower left is probably EGR, front right small one no idea, and the one on the upper left in the rear is a NON vacuum, clean air port. On Olds that was for the heated choke to pull air from. On yours, no idea.
Both EGR and vac advance are going to be ported. Look down the primary throttle bore on the "forward" (as in vehicle) edge of the primaries, and you will see the two holes for the mix control needles. Above those, you will likely see at least two more slots or holes, which is what is what feeds any "ported" vacuum devices. You can stick your finger over one hole, and blow through the fitting. That'll tell you which does what. Just because the holes and fittings LOOK like they line up, doesn't mean much.
You'll also have the THERMAC to run off of vacuum, that would be another small line or tee. I'm sure I've missed other vacuum devices, but others will know.
