Renault 19 fuel gauge - Mookfish
Hi, for some time I have been very suspisious of the fuel gauge, as I have been convinced that it is under reading, so yesterday when the gauge showed to be just above reserve I put in approx 27 litres and the gauge settled to just bellow 1/4. Both the handbook that came with the car and the haynes manuel state that the tank holds 55 litres.

So is this definatly a problem with the sender unit in the tank, or could it be anything else? Also I heard that some sender units need calibrating, am I right in thinking that this only applies to modern cars?

Does it show full when it is filled to the top if so there is not a lot you can do about it.

No, it never shows full. Would a new sender unit fix it?

It sounds very much like the tank sender unit is faulty.
