That was what I thought I did when I "slipped it and a washer that was 
there originally on the end of the little hose", but I thought about 
your description again...

I went back out to the shed and pushed the washer and seal (or "gland" 
as I am now informed it may be called - yuk) along the hose- it won't 
go very far because the coiled, springlike hose cover won't compress 
far but the little tip on the end of the hose will poke out.

Now I thought about the tip of that hose poking into the "pilot hole in 
the bottom of the port" as I stuck it in.  Remember, this is done by 
"feel" - but I thought this time I felt it "slot in".

I did up the nut again and...

WOOHOO - yes, it worked.  No fuel spilling out!

Barney to the rescue again - and I have learned one more of those 
"little tricks" that I can pass on to someone else struggling with

Nope, nothing about this in my Haynes
