JEGS Universal Oil Pressure Gauge Adapter
JEGS Universal Oil Pressure Adapter screws into the engine block and allows extra clearance around the distributor, intake manifold and other accessories. The Zinc plated steel design is much stronger than aluminum adapters and doesn't require an adapter for use with an -04AN gauge line. Works with most engines that have 1/8" NPT threads in the block and most mechanical oil pressure gauges.
