Topic: Preventing Breakdown of Fuel Cell Foam
Most people I've talked to recommend emptying your cell after a race to preserve the foam. Some recommend flushing the cell with water, others say to open the cell and remove the foam to make sure it's clean and dry before storage.
I guess my main question is this: is it only the ethanol in gas that eats the foam, or will pure gasoline break it down as well? I'm thinking I could use an external electric pump to empty the cell via the Hydramat pickup (which would get it pretty damn empty), then throw in a few gallons of non-ethanol gas from the racetrack pumps to flush the cell and drive the car onto the trailer.
Thoughts? I don't mind opening up the cell to rinse off the foam and pickup every year or so, but I'm hoping to avoid having to do it after every race.
