Hi Frans
I suggest you contact LAA and ask them for a copy of Mod 10602 which Ian
Rickard had approved. This mod introduces a flange plate and seal assembly
into the top of the tank. The important thing is that the flange seal is on
the inside of the tank so no fuel contacts the out side or the cut edge.
Hope this helps

Subject: Europa-List: Fuel tank sensor opening problem
Dear friends,
In my fuel tank I have cut two small openings for fuel sensors. Serious
fuel leaks started to develop, so I have removed the sensors to have a look.
What I discovered is that in the area around the cut outs the tank wall
has become swollen and seriously distorted.
I remember some discussion on this forum about the treatment the fuel
tank received, that this treatment was only on the surface and once you
cut a hole in the tank the fuel can reach the unprotected material. I
tank mogas and the ethanol in it doesn't help either.
The question is now, what should I do? Is there any way to rescue the
affected material, or should I cut it out?
If I cut out the area, I have a new cut and will face the same problem
but on a larger scale, unless there is some way to treat the newly cut
opening. If I make a new cut, how can I prevent it from happening again?
Of course, replacement of the fuel tank is something I want to avoid at
all costs (and even then, I want to have fuel sensors in the new tank so
I will have to deal with the same problem anyway).
Is there any quick fix possible? This is the flying saison and I don't
want to spoil it if there is a way to postpone a more long lasting
repair until the winter.
Thanks in advance for some great ideas,
Frans
