D-102 Breather

D-102 Breather The D-102 is perfect for use with B100/Bio fuel 55 gallon drums. It comes with an adapter which fits the small bung thread. The unit is kept on the drum/s from beginning to end to protect your B100 from water and dirt ingestion. B100 is like a sponge and loves water! Water and dirt in fuel can destroy a fuel injection system. If you do not protect your storage drums, water and dirt WILL be in your fuel. A drum breathes air from day to night; by using the D-102 tank breather, the outgoing and incoming air will be filtered through a 1 micron filter keeping dirt out and an effective desiccant to remove water. Result: clean, dry air, clean dry B100! The breather will last months but is dependent on climactic conditions in your area. An inexpensive insurance policy for your fuel, your engine!
