It is roughly under the shifter.
In the center of the car causing less weight upset when burning the fuel

Fuel pump in a Fiero is electric. It's in the gas tank. Gas tank's in the middle of the car. Drop the tank. Pull the pump.
The Fiero Fuel Pump Pulsator is located in the fuel tank connecting the fuel pump to the tube leading out to the engine. It has a rubber insert that connects both tubes (the pump being one of them) It is supposed to smooth the fuel flow but many have yet to determine a difference if it is removed.
The fuel tank is located up under the car in the "hump" between the seats. It takes 4 half inch or 13 millimeter bolts to remove it.
Just over ten gallons.
the fuel pump is in the fuel tank. you can access to it by the top of the fuel tank once it's removed.
All Fieros have the fuel pump inside the fuel tank By the way you may be having trouble because there was no fiero in 1977, production was from 1984 to 1988 so your car is probably a 1987
the fuel tank has to be dropped from the car to access it.
the fuel pumps on fiero's are in the fuel tank and I have never seen a shut off switch on them just a fuse in the fuse box under the dash
all fieros have it in the gas tank
the tank is located in between the two passengers in the center console
