In-Line Gauge Adapter, ORB Male to AN Male Flare.  Jamb-Nut style allows the gauge port to be clocked and the ORB port side tightened for proper sealing.

Ideal for installing a pressure gauge where no pressure test port is available.  Perfect for checking flowing pressure at various locations in any bypass or return-style fuel system, finding hidden flow restrictions that create excessive back pressure like a clogged or restrictive filter.  Just locate the gauge and gauge adapter between the pump and the next likely restriction and turn on the pump, then compare pressure to the fuel rail or carburetor pressure.  Any reading more than 5-PSI higher than the engine operating pressure indicates a restriction worth investigating.

The Aeromotive line of custom fittings, adapters and hose-ends are a step above the norm, offering uncompromising fuel flow and positive sealing.
