The bottom pipe I can't see where it's going too?
Riaan it's simple, on the side, left hand side of vehicle, there is a short pipe that comes from the bottom of the black box (see pic) and goes to the top to the existing Diesel filter. Remove the pipe then get two banjo connections and approx 500 mm of new similar pipe and two good pipe clamps, make up a bracket for the new fiterhousing that you place just opposite the attachment, connect from the bottom pipe to the top of the filterhousing and from the side of the filterhousing to the top connection.

Riaan the Diesel will flow through the additional filter first and then through the original filter. I found that the original filter does not have to be replaced, maybe after 100k km! As for the additional filter have made the experience that needs to be changed every 5th or 6th oil change, it really depends where do you fill up , certainly if I go on back roads and fill up in dodgy places like in Moz or Zim I have the additional filter replaced otherwise every 5th to 6th oil change that's my 5c worth ;)

You wont Chris, you will have to open the bottom tap en drain the diesel after suspicious diesel or on every service.

That second filter is so cheap if you look at the cost of injectors I would replace mine every service.

Think the service manual says change diesel filter every 80 000 km but I don't think that's a good idea if you don't have a second filter at least.

Toyota bakkies initially also had their diesel filters changed on 90 000km under warranty and it cost them a lot of injector failures under warranty.

Riaan, I know the original diesel filter on a Prof is difficult to replace, or so I am told? (like in a bush repair). Any idea about how difficult to drain and replace this pre-filter please?
