Yep I took a look at the tractor an hour or so ago and found the plug  
well and truly hidden under the hydraulic oil pipes - so much for  
that good idea <g>.

Yes, I don't think there's anything (much) wrong with the gauge.

I'll do that sometime "soon". But circumstances of an upcoming trip  
to New Zealand then surgery on an ankle that will lead to crutches  
for a month might mean that "soon" isn't until next year.
