I have an Aviaid dry sump tank (7.5 x 14) which I can't seem to get to seal completely around the center v-band seal. It has never sealed completely and I've taken it apart and tried a few times to determine the problem, but no luck so far. I've read that others have had similar problems, but there is no clear solution. I have the whole thing apart and cleaned up again and would like this to be the last time I have to deal with the slow leak. I sent an email to [email protected] a week ago asking for some suggestions, but have received no response. Please see the attached photos to clarify the situation of the v-band, o-ring, and top and bottom halves.

I also noticed that the 7.5 x 14 tank pictured on their website, http://aviaid.com/shopsite_sc/store/.../110-57520.gif, has a bolted flange around the center rather than the v-band clamp. I wonder if the flange is a newer or older design than the v-band. I'm considering taking this tank to a fabricator and having it modified to a flanged center seal. I am guessing that it may be cheaper to modify it to seal properly rather than replace it. Again, please let me know if you have any suggestions about getting this sealed. Maybe I am missing something. Maybe I am doing something wrong. Please let me know what you think or if you have questions.
Thanks,
