Fellow builders, I'm shopping for some quick-drain fuel tank valves. In years past I've always used the Saf-air types, but it looks like they have decided to make the valves non-rebuildable. This isn't entirely clear on their website, and it may not be true. They have conflicting information. Does anyone know of any competing products that are available for a 1/8 npt thread, preferably in a flush form factor?
