oh crap... got cold and hot sweat at the same time. I just figured out why so much material came of from the holes in the feet of my fuel pump.

I reamed it #12 for an3 bolts as I saw the nutplate numbers.

That was all wrong ! it's supposed to be #19 for 8R8 like screws. They even use special head hex screws to clear the hex screws holding the head plate on the tube and any other screw will fit, even the larger an3 size hex screws won't.

grrrrrrrrr... I hate those mistakes.

After a bit of research and finally contacting Andair, I figured out that you can unscrew the feet and Andair was so kind to send me new ones at cheap price compared to replacing the pump.

Now I have to figure out how to fix my center cabin cover, that also has holes in it for AN3.
