Hey Robert: The corrosion comes from water in the fuel. Do you store your
Coupe in a hanger, or outside?
What type of fuel caps do you have? That is are there fuel gauges in the
caps? Are the gaskets real tight, and the caps hard to turn? Or are the
caps easy to turn? Do you often get water in the fuel sample?
Sometimes water can be trapped in the fuel tank and not come out in
the fuel sample. Have you tried suctioning out the fuel tanks? (I guess I
should have asked what serial number your Coupe is and what kind of fuel tanks
do you have?)
Sorry for all the questions.

Dear all,
Sorry for my non technical knowledge and lousy English, but I try to
explain my problems, thanks.
With the annual we found in the fuel pump a lot of white powder, the
outgoing tube was practically blocked.
I found in the 2006 October issue of Coupe Capers an article about this
strange problem.
In Belgium we may only use 100LL and it is forbidden to use auto fuel.
I have to replace the pump who is only 3 years old, was replaced in 2006.
The inside corrosion is enormous.
Because this year I had a medical problem and only have 25 hours on the
counter.
Someone had that same problem?
My carburetor is leaking if I leave the main valve open, not so much but
enough. So I shut it always (when I am not flying)
It is a Stromberg, that one was also controlled 3 years ago and was then
much better, but it start again leaking.
I have a Continental C75-12. Is an other type of carburetor available?
I enjoy my Coupe very much and I am very happy with her, if I can fly.
Thank you very much for you help, I am a silent daily reader of the
Tech-Yahoo and you are fantastic with your discussions
Specially the clear and useful solutions you all give on the problems, but
Hartmut responses short and right to the point, thanks.
With kind regards,
Robert
