I've got an Andair FS20x4 fuel selector valve - about 6 years/500 hrs old. Recently, when I shut the valve off, it still allows a slow, steady drip of fuel to flow through the fuel line to the carburetor.
I have a tee between the valve and the carb with a Curtis quick-drain, so I tried cycling the valve multiple times and allowing full-flow through the quick drain so as to hopefully flush out the fuel selector valve, but it made no difference.
I don't see any mention of a overhaul/repair kit for these valves when I looked at Spruce and Andair's website. I've emailed Andair for information, but does anyone know if these valves are DIY repairable, repairable by Andair, or do you simply have to replace the valve body?
