my 94 eldorado has it in the dash board glove box.
Mounted on top and inside the fuel tank.

the lach under the dash will not open the fuel tank on my 2000 bmwi
They hold around 20 gallons. If you run it clear dry you might squeeze 22 gallons in there.
In the gas Tank
drop the fuel tank, it is on top. But before you do that, make sure your fuel pressure regulator is not the problem, probably is.
The eldorado requires the fuel tank to be dropped from below the car. This is not a job for a novice and should be done at a shop on a vehicle lift. You will also need to disconnect the battery before starting to prevent a fire. You would need to drain the fuel first to make it safer/easier to handle.
Fuel tank capacity is around 20 gallons.
in the gas tank
It's inside the gas tank!
In most models, the button to open the gas cap is located to the left of driver on the dash near the driver's armrest. To open the gas cap, simply press the button.
I HAVE A 1983 ELDORADO IT'S IN THE FEUL TANK. IT BETTER TO LET THE DEALER CHANGE IT IF YOU DO IT YOUSELF YOU HAVE TO BE REAL CAREFUL.
