Hello! I have a deli oil pressure gauge that is 1/8 PT, that was connected to a greddy oil relocation kit that used the same fitting. i just installed an HKS oil cooler kit, which also has a sandwich adapter. According to the specs it's 1/8 PT, but they don't seem to work together. Has anyone else had this issue? Is there a conversion piece that is needed in order for this work?
according to the greddy website, their sandwich adapter is 1/8 NPT, which is strange that it would work without any issues since the gauge is allegedly PT, not NPT.
