Dear Friends: Here, in Brasil, we prefer fuel tanks made with aluminum (best alloy is 5052 - used for boats) . But why? Many guys here are using autogas and our gasoline has up to 25% of alcohol.
Not immediately, but in a few months the alcohol reacts with the resin (epoxi), so we have a kind of "gum" that, very often, obstructs the carburetor. Regards for all, Claudio Holanda Brasil ----- Original Message ----- From: "Darren Crompton" <kr.2s.dar...@gmail.com> To: "KRnet" <kr...@mylist.net> Sent: Tuesday, June 05, 2007 4:20 AM Subject: Re: KR> Foam filled tanks. > JG > > Here in Australia we have a saying that goes "RTFQ" > If you read the question, you will see that nowhere did I mention about > building the fuel tanks out of fiberglass.
