On O'l Betty E indercated "Enough"

i just fuel my car up when ever i drive it ,its kinda a habit but id rather not run out of fuel haha

That is all good info, But in the end its a resistance guage and any corrosion on the sender will affect the reading (also in the wiring loom), and so its different in every dato to some degree.

I can not only start it, but I can drive it 20 miles [32k] to the fuel station to fill it up again.

Remember that I have a 1200 coupe & you have a newer model so the amount of 'useable' fuel may be more or less.

If you have an owners manual for your car, then look in the 'specifications' section to find the fuel tank capacity, then drive it till it is ont eh 'E' mark & fill it up. You can then quickly calculate how much was still in the tank.

Next, do a couple of mileage tests to see ho far it goes [on average] per gallon or litre.

If you calculated that there was 6 litres in the tank [for example] when the gauge read 'E' & you get 15k/ litre then multiply that number by HALF of the fuel that remained in the tank.

Lets see, .. in this example we multiply 15 x 3 & get 45k [about 27 miles] of reasonably safe reserve after it hits 'E'

Your actual calculation will naturaly be different.

Hi Dodgeman

So guess that there are 5 ltrs in the tank ,ok tell me when it comes to E are you able to start your car ? then we can get an idea how much of minimum fuel that you want to start the car.

Thanks

My 1200 coupe has a 35 litre fuel tank [according to the manual] & when reading exactly on the 'E' I can squeeze 30 litres into it.

You do the maths.

It is not theory. On my 1200 it is fact. But your 1200 may differ. You can find out for sure by driving it until it runs out of fuel. Then you will know.

The lesson to learn is that it is "normal" for the 1200 to haveplenty of fuel when the gauge is on the lower mark. Don't bother trying to fix what is not broken. If you wish, you could try to calibrate it, but it is not required.

littledarkone, I did the same as you and it made the guage work properly, I had to do it a few times and tested it with a multimeter each time. Hardest part was getting the sender out that was a pain.
Oh and no liquid required.

Hi Littledarkone

Polishing is quite enough if you have corroded contacts , But My case is different i got broken silver stripes on my dash board so the connectivity is not there between, no other option i had ,i gave it to so many electrician , but none could weld it with electric,so i found a way it is success only you need thin silver stripes and a proper glue,
So i am happy and learned something that is

"if you put little more extra effort on any thing it is possible "


Thanks

silver tape on the resistor bit hey? I pulled it out a few months ago and polished the contacts with a bit of wet & dry sandpaper hoping it would help it read right but i didn't. The other thing was even with the igintion on about to start the engine the gauge wouldn't read anything when I was moving the arm on the sender. Do they need liquid or something to earth the sender?
