True proportion of premium grade fuel-quality failures

The Ohio Department of Agriculture tested 203 fuel samples across state in 1999 for accuracy of reported octane level. For premium grade, 14 out of 105 samples failed (they didn't meet ASTM specification an FTC Octane posting rule). How many samples would be required to make a 99% confidence interval that is in 0.02 of the true proportion of premium grade fuel-quality failures?
