Product Description

This is a vented version of our common Filler Cap and Bung. These caps use the same standard bung we have used for years. They have a small .040" hole for venting with a replaceable brass vent fitting installed on the inside to reduce liquid sepage. These filler necks are used commonly for gas tanks, oil tanks thant need to be vented, or any other fluid container that does not need to be completely sealed to the atmosphere. It's small diameter keeps it from drawing to much atttention but the filler hole is pleanty large enough to fill with any type of nozzle.  Uses a replacealble fuel resistant o-ring for a trouble free seal.
