I successfully create fuel line out of silicone rubber!?

This patent seems to indicate that calcium carbonate can give "room temperature condensation curing silanol terminated silicone" fuel resistance: http://www.google.com/patents/WO19990...
So maybe this technique could be improved by mixing a bunch of that in before extruding it.
