I was talking with someone about bypass oil filters and the use of a sandwich adapter that would allow for bypass oil flow, oil pressure and oil temp all in one go. If I remember correctly, the Glow Shift people have an adapter that is close, but would have to be modified to fit on a Delica. The Frantz people seem to have some that are made to order, but I cannot remember the thread sizes and settings (nor have I been able to locate them on the forum) for the L400 oil filter mounts.
Has anyone found a sandwich adapter that works on the L400? Does anyone remember the thread sizes and settings for the filter?
