I would have expected no corrosion found since your tank is plastic so any rust particles will have been in tbe fuel already, since it may have been stored in steel tanks along with any water collected during transit and storage. . Maybe some rubber particles from the fuel system and any other foreign matter collected over 10 years that woud indicate the quality of the fuel used over that time period. Would be interested to see what was actually in the filter but i suspect you'd have binned it now anyway?
