Trying not to think about tyres.......

Still some small jobs to be done:

The SVA test requires that the clutch and brake pedals are non-slip, mine obviously are not:No problem though as I've got some of this stuff:It is like (Very) Coarse sandpaper on a rubberised adhesive backing. That bit has been stuck on my vice for two days and is pretty difficult to get off!! So after one last time in the footwell.... job done:I have yet to fit the engine bay dummy vent louvres... mainly because GD don't have any in stock. If I did nothing then the rebate in the body has a contactable edge which is a borderline fail being just less then the 2.5mm radius required. This was solved with some 0.5mm aluminium plate and some silicone: This converts the edge projection to less than 2.5mm in which case it only needs to be "blunted". Problem solved. I probably could have spent a bit longer making the plates fit "Exactly" but to be honest I couldn't really be bothered!

One thing I haven't yet tested is the fuel gauge. Fortunately the last time I ran the engine it ran out of fuel. So I added five litres - Moved up to below empty: Added another 5 (10 in total) - Moved a bit closer to empty - honest!!:

Added another 5 (15 in total) - Moved above empty:
Added another 5 (20 in total) - Moved above 1/4:
At least it moves I suppose. I'll keep adding 5 litres at a time ('cos I only got a 5 litre fuel can!) and note the gauge positions so that should give a good idea of what's left in the tank - somehow I think E - 1/2 - F might not be that accurate!

In fact it won't be. The gauge is marked for a float arm that drops below centre and moves up an equal amount above centre - you can see this from the non-linear markings - i.e. 1/4 is nearer to E than 1/2 and 3/4 is nearer to F than 1/2.
My sender is top mounted and moves through roughly 70 degrees up to just below the horizontal, and from my experiments when fitting the sender the resistance did not appear to change linearly with the float arm. So it's anybody's guess really!
So far... E = 12 Litres and 1/4 = 18 litres. It's around a 50 litre tank so looks like I might get to F before 50 litres?
