Re vinyl film: I have been using a soldering iron to cut/melt a line
adjacent to the rivet line then remove only a strip vinyl film at the
rivet line. This leaves a protective film on the rest of the surface
until ready for paint. Of course remove all film on the inside of the
skins!!

Suggest you lightly buff scratch, hit with a little primer (NAPA 7026 in
spray cans is my personal choice along with the aluminum cleaner that is
on the shelf right next to it) and move on. When the plane is done, you
will be going completely over it anyway to repair the other dents,
dings, gouges, etc. that you "will" have.
I started out priming everything but now I am down to doing it only if
the plans say so, else thinking about it if not. I will prime any area
that gets pretty scratched up during the construction phase which for me
is usually along the rivet line as I keep the plastic coating on till
the last instant before riveting. Also I prime between two dissimilar
metals. I lightly buff the affected area so as to increase the grip of
the primer, not to remove the alcad finish.
Personal RV-List Observation #1: One can get way too eaten up with this
primer thing!

Carey,
Make sure the liquid sample you took was in fact gas and not all water.
I've taken full cups of pure water from my tanks and thought I was looking
at fuel.

After trouble shooting the system, it turn out to be my fuel injector. I
pick it up from Southeast Fuel Systems today and the problem was the bellows
assembly. I bought this servo when I had my engine overhauled. The servo
was overhauled by a company in Alabama, not sure the name, but they used a
few after market PMA parts and Bill from Southeast seems to think that was
the problem. The bellows assembly was stainless, instead of brass/berillum
and I had excessive wear on a spacer.
Just glad it happen a 600 ft in the pattern. My biggest concern was the lack
of warning of the impending failure and the fact that I could not catch the
problem on any of my inspections.
I appreciate the help and use most of the ideals to trouble shoot the
problem.
Blue Skies,
Carey Mills

This has me just a bit puzzled.
Sampling the fuel is almost a religion... with my CFI, and now with me.
Wouldn't think to fly without a careful check of the fuel integrity (in
addition to quantity).
A good practice, I think, though it sounds like that may not be the issue here.
