Thanks Owen for the irrdb link. I'll take a look at it.
Thanks BH for the SAE 30R9 number.

As for a few reports of brass floats that are corroded i doubt that it is due to ethanol. The problem is that such floats are made of extremely thin brass. Most likely would have failed anyway over the many decades of use and exposure to water whether due to absorption of water by the ethanol or just any condensation otherwise over such a long period of time.

Same problem with radiators, especialy POST WAR radiators. They are extremely thin material. Have to be to disapate heAT. Not to mention vibration acting on the solder seams of both the the flaots and radiators. Carb floats a little different story. Most moisture will be driven out the carb due to engine heat. Most failed carb floats i've seen are due to solder seams leaking, not corrosion. Again the problem with floats of anykind and radiators is due to extremely thin material that is necessary due to the nature of the float or radiators intended function.
