I want to post this as I was looking and only found one post by a "mechanic". He said to ad ethanol. I did, some stuff thats not the 10% but more like 80 or 90% ethanol I think. Not one drop now.
Before it had a small leak and i drove for a while. My last caddy had small leak for 60,000 miles. This new caddy I filled up with corporate biodiesel of some sort at a pump in San Francisco and that same tank it started leaking really bad. Then I Put 1.4 gallons of ethanol and the rest biodiesel and not one drop.
I'm super impressed. Hope I don't screw anything up with this fix.

If it does work its just a band-aid. It will leak sooner or later again

Any ideas why it works? Dries out the seals? Dries out the fuel? Ethanol and water are not a good combo in most fuel systems. That is why marine fuel doesn't have it.

It makes rubber o-rings swell. I’m not to keen on trying this though. I think ethanol probably has very little lubricity if any.

High concentrations of Ethanol eats aluminum

Not sure but I'm only putting good quality standard diesel in from now on. No leaks still.
