The process of storing fuel and transferring fuel from the storage tanks to the fuel tank of a piece of equipment is a major source of fuel contamination. Connections, hoses, pumps, filters and the delivery system all have effects on the fuel. Between the storage tank and the fuel tank of a piece of equipment, there will be any number of hoses and piping. Damage to and poor maintenance of these hoses and pipes leave opportunities for foreign material to enter the fuel.
