I want to include where the adapter came from for future reference. Remember the adapter should be tapped for a M10x1.0 thread, the 1/8 NPT might (?) fit the banjo bolt.
Kinugawa turbo- (LINK)
Sensor Adapter Oil Water Pressure Temp M18x1.5-1/8NPT,item # 1600-984-013
the banjo fitting came from Ebay- seller autofittings
-10mm Banjo For 4mm Hose M10x1.0 Bolt Fuel Oil Turbo Kit, this was shipped from either Japan or Taiwan, so expect shipping to take a while.
Note I do have three of these left, which includes breather hose and strip ties.
