There are two fuel pumps between the line and the injectors. I doubt
an external filter will have any effect at all.

It HAS to have an effect, it's a restriction.

But is the affect detrimental?

If the external filter handles flows six times greater than my outboard
burns at WOT, what is the net effect of any restriction? And since my
engine manufacturer recommends using an external filter, why would its
use be detrimental in any way?

Your manufacturer recommends a SPECIFIC external filter. It still has
a negative effect because it's in ADDITION to an already existing
filter.

The external filter keeps water and crap out of the fuel going into the
engine.- Hide quoted text -

Isn't that what the internal filter is for?
