Reply to "Fuel tank dimensions"

In most fuel cells, irregular chunks of open-cell foam are forced into the tank openings, thus restricting fuel slosh without the need for metal baffles. Gasoline eats any foam up over time, so in most cases, the chunks are pulled back out and new foam is added. Otherwise, small bits of foam begin to get into the fuel lines and plug things up. Foam replacement is a messy, sort-of-dangerous job especially for those with chemical allergies. May be best done by the cell mfgr.
