OK guys,
I never let my fuel get down below R. but close to it, before filling. when i do, it only takes about 14 gallons US. then the gauge goes up to above F, and if i keep at it, the expansion tank and the whole car stinks like gas. I just read again that the tank capacity is 82 L or 21.5 us Gallons.
So is there really 7 gallons left in the tank below the R on the gauge? Someone has got to know. Help? Please?

Very doubtful. You can always open up the plug and drain it or the access plate on the top to look inside the tank.

good advice. Maybe I'll just drive the 5 miles to Joe Alexander's place.

Per my owners manual the light means 22-25 miles left which I believe would be about 1 gallon.

I have recently emptied the tank to know excatly when the fuel reserve light light up because i have never seen it switched on as i refuel before the needle is too low. Also my gauge stay high after filling but goes down quickly after 2/3 or 1/2 .
What I saw is that the reserve light is on when i have less than 5 liters .
Under is my scale when i have fulfilled my tank :

Yves, I frequently fill mine to 65 liter of fuel (17.2 gallon) or on occasion 70 liters (18.5 gallon). Don't you ever get that high?

Is the cork seal at the fuel sender unit intact or is it seeping with petrol?
Do you have a big dent in your tank?

Peter , the 40 lit level is not full , it is what I had in the tank when I have tested the reserve.

I have noticed that my fuel gauge needle can be somewhat erratic (jumpy) depending on the road surface. On a rough road, the needle can make huge swings. On an incline or downhill, the gauge will always read differently. I’ve pretty much just written off the fuel gauge as a poorly functioning system. Im wondering if others have experienced the same. As to the accuracy of the readings, I have lost all faith in mine. I routinely do a fill up when the gauge reads 1/2 even though I have no idea how much gas is actually in the tank.

Hello, my needle is pretty stable, but the slightest incline can move the needle significantly. i guess the condition/resistance of the wiring and the sender unit can all play a part. The only time i'm confident that the gauge is accurate is after i've filled the tank up, after that it's like Russian roulette! I just get into the habit of filling it regularly and ignore the gauge, and the clock for that matter!

My fuel gauge acts erratically when I first start and drive the car. It reads lower than it should.
But in 5 mins it seems to correct itself. It bounces around a good bit too. I also pretty much ignore it and fill up at a quarter tank.
...just one of those endearing aspects of owning a 60 year old classic car I guess.
Mike M, hope you find the source of the gas odors.
