Fuel gauge reading wrong
Wonder if any of you knowledgeable people can help. My tin-top Escort got a new fuel tank put in a few months back, and ever since then the fuel
gauge has read wrong - basically when full it shows just above 3/4 and when empty (or as best I can guess) it is way past the empty mark.
Is there anything I can do - reset/recalibrate the gauge? Or is it likely to be the wrong sender has been installed or something?

Might be worth checking the connections , sounds like a high resistance somewhere?

You could try putting a resistor in series with the sender, you will have to do a bit of trial and error to get the right one though, I have put a 10
ohm in my car to make a correction on the gauge.

hmmm sounds like more effort than I was hoping for (i.e. not a lot)...will see if I can get to the connections ok and give em a wiggle - otherwise
I'll have to live with it...

Did the fuel level sender come with the new tank? or have you refitted the old sender?
If you have a new sender in the new tank then you have got a euro sender which reads the other way round from the older Ford UK/USA format i.e old
ford 230 empty to 30 full.... more modern euro guages 10 empty 180 full (Ohms).
Last week i took the old ford sender out of my car un soldered from 1 end of the reostat and re soldered to the other end, gauge still does not read
the full range but at least it reads the right way round now

don't know if it was a new sender or not - paid someone else to install the new tank. The gauge reads the correct direction, just isn't
pointing at the correct bit.....
So if it used to be 30 to 230, and is now a 10 to 180 - is there anything I can add to correct this, or am I stuck (i.e. something to turn 180 into
230)...sorry for the daft question, when it comes to this level of electronics I'm clueless!

My Quantum Extreme was exactly the same.
All I did was to shorten the fuel sender float arm.
You could have the same effect by simply bending the arm so that at its highest point it is flush with the top of the tank, and at its lowest point,
level with bottom of tank.
Hope this helps, I know 1st hand how frustrating it is.
Something about this, so very wrong.....I have to laugh out loud, I wish I didn`t like this!!!!!!!!!!!!!!

sounds like incorrect sender fitted.
you cannot correct it with a resistor - putting resistor can make one end of the range correct but screws the other end.
e.g. it can read full when full but then half empty when totally empty.
