The fuse box on a 1986 Buick Regal is located below the dash near the brake pedal. It prevents circuits in the vehicle from being overloaded.
I have a 1992 regal and it is located under the glove-box behind a piece of black plastic.
The Buick Roadmaster was not produced in 1986. They were made from 1991 to 1996.
Not practical to try to fix a heater core. Replace it with a new one.

A Chevy 305 produces:130 HP - 250 HP A stock 86 305ci Regal will be the 165 HP or 190 HP version.
Do they have the same engine? If not, then no, it wont work. If they do, make sure they have the same fuel pressure requirment. If the engine and pressure is the same, they should be interchangeable.

There is no adjustment of the pump. You can adjust belt tension, by loosing and adjusting tension with the bolts holding it in place, but that is all.
It is under the dash on the pass side and requires a bunch of work to get to it. Take it to a garage.
