Fuel tank sender

Post by Wollop »

Does anyone know if the GS sender and the GSA sender are interchangeable? GS has two leads and GSA three.

Our 1980 GS has a sender with three leads which I imagine is a GSA unit, the car being late and during the changeover period.

It looks like it doesn't work and needs replacing.

The gauge rises to 'empty' with the ignition on and no further. With two leads to the sender connected to each other (briefly) it rises to 'full'. So I guess that means the circuit and gauge are OK.

Hence it looks like time for a replacement sender. Not sure which one and neither sort is cheap!

Suggestions appreciated.

I'm told that from July '79 when the GSA is launched the GS uses a GSA sender.
