I have a couple of questions that I hope someone can help me with.   First of all, someone on the list a while back referred us to a supplier for a remote spin on fuel filter and bracket.  I have lost track of where I bought the thing and I hope someone remembers.  The only markings on either the bracket or the filter are, 10 microns, 60 GPH, and ethanol approved.  I need to buy a replacement so …..help?

The other question is about the fact that the filter says “ethanol approved” on it.  I have been very careful to not let any ethanol get into the plane, yet, when I removed the filter, the o-ring closest to the fuel is swollen and will not go back into its proper position.  The only thing that comes to mind that could have caused the o-ring to swell is that I add a 50/50 mix of Marvel Mystery Oil and 2-cycle oil.  Since there has been no ethanol, could the MMO have caused the o-ring to swell?
