The manifold absolute pressure sensor on a 1989 Firebird Formula is attached to the passenger side fire wall just above and to the right of the air conditioner evaporator housing. There is a three wire plug and a single vacuum line connected to the bottom.
Just an educated guess, but I believe all 1992 305 Camaro's had TBI (Throttle body Injection), the 1989 Firebird 305 does not, other then that I don't know of any difference unless you have a more specific question...
I show 49,048 Base Firebird & 15,358 Tran-am

If they are both Chevy V8 cars it will bolt up.

The 1989 Firebird typically has a fuel tank capacity of around 15.5 gallons.
Well it depends on your engine size. I have have a 1989 firebird formula model with a 305 5.0 engine. When the engine is cold, it will go into high idle, with the oil pressure gauge between 30 and 60. After it's warmed up, at idle, the needle should be just above the red line. As crank speed increases pressure will increase, so it will depend on your speed and RPM while driving.
15.5 Gallons
It should be on the driver side, above the pedals but under the steering wheel on your left. Turn the screw and pull off the cover. Hope this helps.
If its a V8, its going to be .035
