Fuel cell for Alcohol

I was reading somewhere that natural aluminum fittings are not compatible with alcohol, and was wondering what type of fuel cell to use. Do you guys use a plastic cell or one with a rubber bladder?

aluminum is fine, some say they dont need to be anodized but I never took the chance as I have a place here local who does it real cheap.

or plastic is fine.......

I used a plastic tank for mine, mounted up high in front of the engine to gravity feed the mechanical fuel pump. I never had a problem with the aluminum fittings as long as you flushed the system out at the end of the year, and kept it wet for the weeks during racing season.

I've always had an aluminum tank and aluminum fittings.
