Re-installing boost pumps

TLDR

  • Reinstalled boost pumps and tested for leak

Details

Previously I sent my boost pumps back to the aeroinno factory for service bulletin. They sent the repaired units back recently so I reinstalled them back on the wing.

The work is exactly the opposite of the removal. I did ran into a bit of an issue when securing the AN fuel lines.

So basically when I removed the lines, not all fittings were required to be removed. Due to this, some part of the fitting was almost clocked to certain angle. When I connected everything, I needed to be super careful about the angle so none of the lines were twisted.

After putting everything together, I pulled out my trusty tyre pump and snoop leak detection liquid to conduct a leak test. I did not observe any bubble so I think we are good for now.
