For quite a while the fuel gauge never showed a full tank after I've filled up. Didn't really bother me, until the gauge showed nothing after about 140 miles. This was not helped when the low fuel light failed to show after 210 miles. Although it showed the following morning. Once in a while I have sprayed the connector block on the right hand side, behind the plastic cover with ACF50, I may even have put waxoyl in there. I took the block apart, as I read ages ago on this site that it can be a problem. Blasted both sides with WD40 for several long seconds, put it back together, made no difference. But, next day it was working. Fingers crossed it stays that way.
