Duncan,
During this current thread, I introduced the assumption that the Europa
tanks are made of HDPE. Based on the extensive bulging some have
experienced, however, my source of much more knowledge than I possess
assumes it might be LDPE - which he in general does not find suitable for
gasoline containers. There are some unfortunate "Europeans" who can attest
to that - - - - .
As others have stated already, gasoline composition varies from brand to
brand, etc.
The fact that your non-fluorinated tank has not bulged is quite interesting.
What type of fuel have you used - unleaded mogas or leaded Avgas?
