Default Fuel pump nuts loose

Just a heads up, I am doing my CI and was putting a wrench on everything on the engine to check tightness. Found the fuel pump mounting nuts loose. Visually, they looked secure but the top was a 1/2 turn loose and the bottom was 1 turn loose. Retorqued and applied torque stripe.
Also, I found the lower bracket (attaches to the top of the generator) that supports the ignition modules/coils broken. The bottom coil was chafing into the engine mount. Luckily it only chafed through the paint.

To add to the list of bolts coming loose the head bolts on the #1 cylinder loosened and a small oil trail was the indication. I consulted with a Rotax engine rebuilder who advised these head bolts need to be checked and he gave me a torque value. Once I re-torqued the #1 cylinder I had no more leaking. I checked the other cylinder heads and the torque was good, and also no leaks.

I used some torque seal ( witness mark) on the visible head bolts and two years later all good and no leaking.
