What adapters do I need to install a Fuel Pressure Gauge in my Chevy Duramax?

In order to install one of our Fuel Pressure gauges in your Duramax, you must have an aftermarket lift pump installed.  You can use a 6.6L Pressure adapter, GS-FA_Duramax, when installing in a 2000-2013 6.6L which replaces the stock bleeder screw next to the filter housing to easily install a ⅛ - 27 NPT pressure sensor. Thread size is M10 x 1.5.
