What materials are incompatible with biodiesel?
• Natural rubber, butyl rubber and some types of nitrile rubber (depending on chemical composition, construction and application) may be particularly susceptible to degradation. Also, copper, bronze, brass, tin, lead and zinc can cause deposit formations. The use of these materials and coatings must be avoided for fuel tanks and fuel lines. Fuel fittings and connectors are acceptable due to the small surface area in contact with the fuel. Note: Contact your vehicle manufacturer to determine if any of the OEM supplied components are at risk with biodiesel in order to prevent engine or vehicle damage.
