Unfortunately the gauge doesn't quite agree with the sending units position. It takes a lot of lift to move the gauge off empty and it will not read over 3/4 full. It is a relatively simple setup and I couldn't see anything wrong so I cleaned it off and put it back in. I wonder if the problem is with the gauge or the sending unit?

>Hi all, I was reading in the local paper that the gov't is soon going to require that gas contain 15% ethanol up from the 10% that is currently in it. They interviewed a classic car mechanic who said that ethanol at the 10% level was causing seals and hoses to turn to goo, and the the new limit would only make the problem worse. I know I have a lot of engines, chain saws, trimmers, lawn tractors etc.  that were designed for 0% ethanol, is there anything I can do limit the impact of the new fuel on my equipment? Or is it really not a problem.
