On eBay right now, there is a used Zenith fuel Filter. Although it is thoroughly used, it seems to be in decent rebuildable shape. It may be difficult to get the bowl crystal clear again. Then again, it’s 70 years old and a little patina is to be expected. Although we have a few NOS Zeniths for sale on this site, this is a great item for someone who derives a great deal of pleasure out of transforming the rough into the pristine with their own hands. Please note, the retainer is attached incorrectly, hence the need for the spacers between the thumb screw and the bowl.
