here is my dilemna....

I work offshore and am gone 4-6 weeks at a time.
My holley carb leaks everytime I get home.
Last hitch it was the rear bowl, this time I fired it up and the front bowl and the balance tube o-ring were destroyed.

I don't really mind replacing the gaskets/orings every year, but 8 times a year is getting annoying.
I can only assume this has to do with ethanol in the fuel? as it doesn't seem like it was a problem in years gone by.

Finding fuel with no ethanol is nearly impossible, so where can I find gaskets/orings that'll stand up to the stuff?

or do I just need to drain the bowls everytime I leave and hope for the best?


many thanks,
Drew
