OS 160FX and pump question

[LowPass]

Use a piece of brass tubing (overtop of the drill bit) slightly smaller than the screw hole
to protect the threads while you are drilling ...

Works great!.

  Order the pressure tap for the 1.40EFI from tower for a couple of bucks.  You drill through the bottom of the backplate screw hole on the upper/non-exhaust side (it emergees into the intake transfer port and replace the backplate screw with this part.  It is a very neat, clean way to to it.  No tapping required (I HATE tiny little taps....).

    Ok, maybe I'm missing something obvious here. But, I have an OS 160 FX and a Perry V30 pressure type pump. Where in the heck do you tap this thing for pressure? There's usually a boss in the center of the back plate, or the back plate is smooth, or something. This engine has raised egdes that wouldn't allow for very easy drilling and tapping. 

    Any suggestions from those that have done this?

    thanks,
    -Mike
