Sounds like an earth issue to me, i used to have an fc in the 70's that had a fuel guage that would go to full when you filled it up and it would stay there untill you had about 20 miles to empty,at that time it would start to move and bounce and head in the  general direction of empty fast.

Thats what I am thinking but its all the way to the right no matter what unless I cut power. I can't work out where the bad contact is though. thought it was the brown wire so tried to clean it without ripping everything out.

Guys,
There are a couple of things that could do this. Make sure the plastic is in place on the two post connectors on the back of the gauge. The conector post marked sender should not "earth" or touch the gauge metal. (neither should the power).This would create the condition that the guage reads full.It could also be faulty sender units. This could be tested by removing the sender wire on the gauge.If it goes back to empty then the sender is faulty. Waynos if your gauge reads full without the sender wire connected, then i believe you have the above condition (terminal post touching gauge metal) or simply a faulty gauge.

i think you will find early holden fuel gauges read high when open circuit IE crook sender or poor connection between sender and gauge as they are not a bi metal type gauge,earth the sender wire at tank and see if it returns to empty,also run a test earth at a known test point directly to the sender housing to ascertain sender earth,remember the gauge earths through the cluster housing
