Monday 8th June 2015.  Here's the fuel sender unit after clean-up and assembly.  Replacing and re-soldering the internal resistance wire float runners and the warning light circuit makes cleaning the internals much easier.  Using a micrometer, I discovered the thickness of the resistance wires are 0.1mm for the float and 0.27mm for the warning light.

Monday 16th March 2015: Recaro 'R' replica seats arrive from deser.it in Turin, finished in black vinyl with black and white pepita cloth inserts.  These are amazing and incredibly comfortable!  They'll base-mount - the plan is to take these out when racing and replace with FIA race seat.
