This was over a couple of days but I don’t count planning things in this log as hours. Otherwise you could say a builder spends years just thinking about the project items.

That said I thought I’d share a bit of the process. I’ve bought a few of the engine/fuel components a bit early so I can position them in the plane before I get to the engine install.

Pic one shows the dual fuel pump, which is distressingly heavy, the post fuel filter, the fuel pressure regulator and an Andair valve switch that I’ll be selling on as it is 3 position and I only need an on/off.

Pic 3 has the sump walls just placed in position around the hydramat which is also a 15 micron filter and will act as my ‘pre fuel pump filter’. I thought about how to position all these things down the sides of the sump tank or in the hell hole. That “hell hole” is pretty hard to access so I ruled it out. If I ever had a fuel leak I want to be able to get to things quickly and easily.

I’m going to put the pumps and filter ahead of the sump and make a sloping cover for it. There needs to be a gentle angle from the sump anyway for the ferry tank bladder to sit without sharp corners so this is a two in one solution. The regulator will go in the left side cavity and the stop valve that side controlled from the front seat for emergencies. I’m not sure if I’ll pay the big bucks for another Andair Valve or gerry rig something much cheaper.
