It should be located in the fuel tank because I have an '87 and mine went out on my 5 days ago and I found out where it was!

The Buick Roadmaster was not produced in 1986. They were made from 1991 to 1996.
How do you Change a fuel pump on a 1985 Buick Century?
Mounted in the fuel tank on top.
The fuel pump is in the fuel tank on a 1985 Buick Electra. Disconnect the battery. Unhook the filler neck. While holding the tank up with a jack, remove the tank straps. Lower the tank enough to disconnect the fuel lines and wiring. Take the tank out and remove the top plate to replace the pump. Install everything that was removed.
On a fuel injected Buick you must remove the fuel tank in order to access the fuel pump.
Drop the fuel tank.
Possibly. Replace the fuel filter to see if that solves your problems.
The fuel filter for a 1999 Buick century is located on the drivers side frame in front of the fuel tank. It is an inline type and is easy to change.
Drop the fuel tank, then it's right there.
Located in the fuel tank - probably have to remove for access
