Boater sues over ethanol-laced gasoline's effect on fiberglass fuel tank

Something was wrong with Sally Ann.

For months, she sputtered and choked, and Barry Treahy's remedies weren't working. He kept changing her fuel filters. Then he rebuilt her carburetor. Finally, he cut into her gas tank, cleaned out the mysterious caramel-colored gunk and patched her up -- twice.

Disaster struck on a summer day in San Diego, when Treahy's beloved 20-foot fishing boat was parked street side with the outer hull plug open to drain any residual water. The boat's 55-gallon gas tank failed and gasoline streamed into the bilge and down the street.
