Fuel Gauge help - am I stupid?

[Paul Y]

Morning all and Happy Fathers Day!

Apologies for the radio silence, still here, still pick away, but a small challenge at home has meant I have not been as active on here as late.

Anyway, I needs some help.

Background.

Have moved my fuel tank to the back of the truck using a Jeep tank and a Blazer fuel basket and sender.

Deluxe dash.

Rewired using a loom that I cant remember sitting here at my desk.

Anyway, fuel gauge didn't work. Tested wiring and gauge and deducted gauge faulty.

Ordered new gauge and box of tricks to enable old gauge to work with new sender.

Installed both.

Gauge now goes to full whatever I do with sender.

Tested Continuity - all good.

Tested voltage across gauge - 12 volts?

So... This is my questions (s)

Which wire goes where on the gauge - picture below.



Should there be an insulator that goes between the gauge and the metal 'pod' it fits in to stop the gauge earthing out against the 'pod'?

I have the insulator that goes across the terminals once it is bolted into the 'pod'.

It feels as if I am missing something but my brain is too tired to work it out.

Hopefully it is just me being stupid and quite happy for me to be told the error of my ways.

Any help and advice always welcome and appreciated.

P.
