The Peterson Fluid Systems straight fitting adapts an engine's 1/8 NPT port to a -3AN outlet and measures 2.25 inches overall. It moves the gauge line connection to a more convenient position for routing and visibility. Use this adapter when converting a 1/8 NPT engine tap to a -3AN gauge line to simplify installation in confined engine-bay locations.
