You do not have to alter the Stock Mercedes Fuel Filter Housing at all to to 1"-14 threads (Infact if you did so it would drill out too much metal and screw up the passages the Fuel gotes througn).

Tha CAT filter conversion has the advantage that by removing the adapter you could still use the Stock Mercedes Filter because you do not alter the origional Filter Bolt.

The spacer plate to move the filter away from the metal casting web below is just a matter of drill 4 holes in a flat plate of metal. That is not difficult.

Below is a pick of the adapter. The central hole is best drilled out on a Lathe but someone who is good with a drill press could do it.
You start with the threaded end of a 1"-14 bolt and you need to drill and tap it for the Filter Bolt Size (don't remember the size right off).

Inside thread is 14mm 1.5 . Tap drill size is 12.7 mm.
