Header tank lid and Access door

Planned out and then marked locations for the holes that will be drilled in the header tank for the fuel inlet, outlet, site tube, and sump drain.  Then drilled holes for fuel bungs (top of image) on the cap for the header tank. These fittings will be used for the fuel inlet to the header tank from the wings, as well as a vent line running back to one of the wings.  The holes have a slight step which will capture each bung nicely prior to welding.
