Thanks mike, I actually spoke to roger at Europa last night, when i was
ordering some bits off him
and asked him about the flourine treatment, and his response was that my kit
#577 had a treated tank
as original, so i guess, I have nothing to worry about or anyone who came
after 577.
Just for the guys thinking about the alloy tank prototype route, you HAVE a
prototype, If you can "Borrow"
one of the original tanks and copy it, Given it is largely flat panels, two
with curves it would be easy to copy
in a light sheet alloy or stainless. I would be happy to loan my tank other
than its installed already, I am sure
others would.

Craig,
It is certainly possible to have your tank fluorinated before installation,
because it is a post-moulding process.
If you look on the web site of a typical rotational moulding company, e.g.
http://tecni-form.com/faqs12.php#12 you can see the answers to a number of
FAQs, such as Q12:
"Is rotational moulding suitable for manufacturing marine plastic gas
tanks?"
"Rotational moulding is actually a very suitable process for the manufacture
of fuel tanks of all types - including those for marine applications. Both
diesel and petrol tanks are commonly manufactured from either LLDPE (linear
low-density polyethylene), or XLPE (cross-linked polyethylene), and for
diesel applications no further processing is required.
"In the case of petrol, post moulding fluorination is used to provide the
barrier properties to meet permeation regulations. However, other materials
may be used, either on their own or in conjunction with polyethylene
(normally as an inner layer) to provide enhanced performance, such as
improved heat resistance or barrier properties."
I sent my early tank back to the company that supplied Europa and it was
fluorinated for about 23GBP (plus return carriage) and returned within a few
days, about seven years ago. I expect any rotational moulding company that
produces petrol tanks would be able to fluorinate yours at a similarly
modest cost, without your having to ship it back to England to the original
manufacturers.
I do not know whether it would be possible to fluorinate a tank in situ.
Regards
Mike

Where can you get heat sheilding and rocket motors for a europa though
graham??
But on a slightly more serious note, IF the tanks havent been flourine
treated
would it be possible to apply a coating to the inside of the tank before its
installed, or maybe
sprayed into in-situ tanks that havent been filled yet, such as a
vinyl-ester resin which may
atleast slow the whole process down to give the existing tanks a reasonable
service life

Hi Bob
apreciate your thoughtful reply.
I wish they wouldn't put alcohol in though, It isn't good for engines
and it is even worse for the environment, takes too much energy to make
it and it uses up too much food, (imho!)
Simple answer, there are already too many of us on this planet, we need
to start colonising space!
