When new, 1990 B2200 manual transmission carbureted trucks had mechanical fuel pump on the engine, passenger side, hidden under the air cleaner, fuel filter also there.
B2200 Automatic trucks had electric fuel pump in the tank.
Fuel-injected trucks had different electric pumps in the tank.
So only one fuel pump per truck. Who knows what'ts happened in the last 22 years though by previous owners...
