Fuel pumps attached to firewall with jubilee clips, and power cables connected.

Today I worked mostly on the fuel pump. It sits on its own mounting plate, but needs to be re-attached, done here with Jubilee clips. I also added the power cables. The fuel pump installation is supplied complete and ready to go, another factor in favour of the 912is.

The Airplane Factory specify not to use the original Rotax stainless steel case, but to fit a “tunnel” over the pumps.The tunnel flanges mate with the rivnuts just visible in the photo above.

I first added thermal insulation to the tunnel:

then fixed the cover in place over the fuel pumps:

The final product looks pretty good, and should prevent engine heat from getting to teh fuel in the pumps.
