The 2.5L Fiero uses an in-tank electric fuel pump which has a working pressure of about
10 psi. The 2.8L Fiero has a similar pump with a working pressure of about 40 psi. There
are many GM cars which use similar pumps. Since it is tedious to replace an in-tank pump,
we suggest using new rather than used. New pumps are available at auto parts stores and we strongly suggest you purchase only AC Delco brand.
