The Moroso fuel pressure gauge fitting adapts a 3/8-inch NPT male thread to a -6AN male fitting, providing a transition between NPT and AN-style connections for gauge or line attachment. It’s intended where a 3/8-inch NPT source must connect to a -6AN line or gauge. This adapter simplifies mixed-thread fuel pressure plumbing.
