Wow, those look huge. My pick up is the standard 3/8 tube. Measured the -8 fittings and hose, 3/8". I thought -8 was 1/2"? The oil filter fitting measures 1/2". I idea was -8 was 1/2" dia and oil filter fitting 1?2", no need to go bigger. If i go -12 will i need to drill and tap oil filter sandwich adaptor for the bigger fittings?
