I have a new poly tank. When I remove the top of the seat back and get the old tank cut out I will take the poly tank and do some fit ups. Then I will more or less copy the plastic tank's configuration doing some optimization and then raise the top approximately 2". Prior to doing that I will mock up the raised configuration of the whole mess to make sure there are no hidden gotcha's. I still need to talk to some people around here to see what the optimum thickness of aluminum (or aluminium?) to use. I did an analysis and a 3/32" thickness of Al would give me a tank about 5 lbs heavier in the stock configuration. I did receive a photo of a tank on the internet but no specifics came with it. Any further input would be appreciated. A 2" height increase would give about 3.5 extra gallons and raise the angle of the seat belts over the shoulder slightly which had been an item of concern in the past.

The carbon is easier to work with, but i have concerns it may be TOO stiff. thats why i thought kevlar matt may be better, or a kevlar carbon weave cloth, with a vinyl ester resin system that is chemically resistant. this would probably give you a tank about 2/3 the weight of the original with the extra capacity. just a thought. craig -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com]On Behalf Of Steve Hagar Sent: Monday, 15 October 2007 1:30 AM Subject: RE: Europa-List: seat back height and larger main tank Yes; That at least is what I am planning to do.
