Andair Fuel Valve FS20X4M

The Andair FS20X4-M is a 3/8" fuel selector valve from the FS20 Type 4 range. It provides clearly defined LEFT, BOTH, RIGHT and OFF selections, with 90-degree movement between each position.

The Type 4 configuration is designed for fuel systems where simultaneous feed from both tanks is required; internal porting provides the BOTH selection without the need to tee the two tank feeds together. The valve uses male connections and is identified by manufacturer part number FS20X4-M; FS20X4-M R2 is also referenced for this item.
