Soz, completely forgot to reply to this. I did not actually have any pictures anyhow. Seems a little implausible what they told you about 'programming the senders to talk to each other'. The senders have no programmable control units built into them, they are simply potentiometers that send a resistance value straight to the instrument cluster, which makes a calculation on fuel level from the two resistance values.
However, if its fixed, its fixed, so happy days!
