More likely than not (and especially if the pump has already been replaced),
the pump is noisy because something is restricting its input.  Dirt or rust
in the tank is one possibility; a restriction in the line may be another.
If so, the new pump will eventually burn up if you don't find the root
cause.  Since you have an '84, I assume you have a pre-pump filter (unlike
some later Vanagons, which only have a post-pump filter). The fact that the
filter looks good does not completely eliminate the possibility of some sort
of blockage or foreign object that is too large travel through the fuel line
to the filter. Remember, the tank is gravity fed; anything in it will tend
to sink to the bottom.
