Hi Folks, I have an Series that had a one wire (positive?) Sender unit. I bought the same sender unit as a replacement. But my Truck is negative ground. I've also read one wire senders match only certain gauges. So...is there a way of using my new sender or do I need to convert to a new 2 wire sender and replace gauge? Hope that's not too confusing!

I'm not sure what you're asking. Is your car petrol or diesel? Which series is it? The diesel sender has one wire for the sender and another for the low fuel warning light

It’s a series 2a. Petrol. I think I took the original tank out. The gauge is the fuel gauge. I guess first question is can I use a new positive sender with negative setup?

Should be okay, it's a resistor. Nothing clever. But depends on calibration.

Have you got a low level fuel warning light and the two wires to connect to a sender with the two terminals if so best option buy a new sender then all works as it should

I seem to recall from Dom and distant past, if you wanted to use a +ve earth sender on -earth system you had to swap the float around so down was up and up was down
