I have had 2 fuel pumps die. The local workshop said this was due to stale petrol (a vehicle not used much). Just what is stale petrol? I presume the pentane put in for cold starts evaporates first, and some of the aromatics with low boiling points. So you are left with mostly octane and heptane, but those are chemically rather intert and would not do much damage. Or does something react with air in the fuel tank (lets say 30 litres if half full)?
