I have just got my new genuine diesel sender unit. The terminals are marked W and L (I think, I have sealed it and packed it awy safely!). W is Warning and L would be level, yes?
Also, the manual says its earthed thru the tank fixings, but there is a third terminal that I assume is an earth - is this just a belts and braces improvement?
Lastly, how do you go about fitting and setting the unit? The manual only talks about reinstalling an existing one, not setting up a new one.
Thanks all (as ever!)
