OS 160FX and pump question

[Alan Hewson]

I just posted a picture of my pressure tap on my OS160FX.
It is just a pressure tap from the hobby shop......4-40 tap size.....drill with appropriate tap drill size first. Tap the hole, clean up the burrs, a drop of Loctite, and snug it in.

  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
