I purchased a 3.0 fuel pump and went to install...

Bit late now, but probably not necessary; the 2.7 fuel pump on my '77 supported a 3.3 RoW 930 motor just fine (in spec for flow and pressure, good AFR's at WOT, power right on the money). Bosch have margins in their specs, like Sachs and Porsche do.

Does this swap typically require different terminals and fuel line fitting?

Higher-rated fuel pumps draw more current and require bigger terminals and fuses. They often have larger hose fittings as well.
