BHK 250 Fuse Direction

Some audio grade fuses are marked with an arrow that should point away from the end in which current enters. For those who want to replace the six stock fuses in a BHK 250 amp, what is the point at which current enters the fuse holder, the rear of the fuse holder or the cap?

New research clearly points to putting the fuse in sideways.

Writing facing up, or writing facing down?

You should chemically or mechanically remove the writing as it creates distortion
