Howdy all. I am new to this site and only two months with a Hannigan trike on a 2009 BMW K1200LT. Here is my problem. On two occasions I have over filled the main tank from transferring gas from the aux tank. Every thread I have read says that it takes up to 20 minutes to transfer fuel from the aux tank to the main tank. I have been overflowing in two to three minutes. Wonder if Hannigan has changed their fuel pump to a more efficient one. Can any of you give me some pointers as to transferring fuel. Thanks.
