vacuum tank

Was re-restoring my vacuum tank ater 30 years of collecting dust in a box. Suddenly occured to me that gasoline is very different now than when it was put it away. Most guys are running electric fuel pumps by now. My question is this. Will the new ethanol fuel eat the " flapper valve" at the bottom of the inner tank. This valve appears to be made of phenolic. The reason I ask this is because I run quadrajet carbs on three of my other cars and had to replace the fiber floats in all of them because the ethanol in todays fuel ate the finish off them causing them to sink. Makes for an ultra-rich condition. Is there anybody out there still running a vaccum tank, and has there been any problems?

Re: vacuum tank

I am using the original setup and it is working just fine. I haven't taken it apart since I went through it a few years ago to know what the flapper valve looks like.

In Florida we have access to ethanol free fuel. Have not had any problems with this fuel eating parts.

Re: vacuum tank

We have ethanol free gas here in Washington state too. A little more expensive, but worth the cost.
I use it in all my small engines such as lawn mower, lawn edger, weed wacker, pressure washer, etc. Ethanol clogs up the jets in small engines as well as causing other problems. Also use it in the Durant because the Durant does not get driven often. Preparing for winter, I run the fuel in the tank down to a minimum and add fuel stabilizer. All help keep things running smoothly.
