Here is the progress of the week: creation of the pipe support, storage box, etc. Plunger arm finished (I still have the hoses to finish), creation of the pipe + turbine / accelerator on the top of the tank as well as the start of the pump.
Rear hitch finished, start of the pumping arm (plunger), there is still a lot of work around the arm but the big one is done ...
Creation of the rear of the tank and of the lift, there are still a few odds and ends to do on it (jacks, jacks supports, etc.).
