I have a IHI RHB5 VJ11 turbo, and i recently acquired a Oil Filter Sandwich adapter, and i'm trying to upgrade the feed line to a SS line. But as i'm searching for a line on the net, their all sorted by AN and i have no idea how to tell what the AN is for my fittings, i know the feed fitting is 1/8 NPT i believe, so is there a way to convert NPT to AN or am i just totally off? HELP!!

 

Depends on what size oil line you want to run. Most run a -3AN line so you need a 1/8NPT to -3AN adapter fitting.
