I removed all the fuel lines and components out of the fuselage in order to prepare in the near future to paint it.
I secured the screws for the fittings and torqued them. Andair states that the first option to secure the screws is to take a center punch and punch the screws which I did next.
Finally I drilled the rivet hole locations where I will be securing the fuel pump and filters after painting and for final assembly.
