1986 745T, 157,000 miles.

I found that the fuel pump fuse was getting very hot. Almost to the point of not being able to touch it. (I did have to change the fuse panel a few years back due to meltage).

The FAQ says that the main fuel pump should draw 6.5 amps.
Where would I check that? I connected my amp meter across the fuse and found it was drawing between 10.5 and 12.1 amps. Maybe that's a combination of the pre-pump + the main pump?

Seeing that high amperage, I elected to replace the main pump. So I put the new pump in and am still drawing 11.5 amps at idle.

Is it likely that the original pump was fine?
