First, if you purchased your Fuji system in 2003 and the threaded connection on the front of your turbine is black then you can safely use an Xpc, G-Xpc, XT, XT-2, GTX or GT-X2 spray gun with it. If the connector is metal colored then you have to make modifications. If you own a Q3 of Q4 there is an 1/8" vent hole on the outside of the turbine on the metal hose connection that needs to be drilled to 3/16" diameter.
If you own a Super turbine, you will need to open the case and either drill a 3/16" hole in the manifold (marked "X" in the picture)
