OK, I have been told the difference in the Digital and Analog Fuel Level Sensor is the color of the sheath that covers the wires.

Digital is white and Analog is black, is this true?

Having problems finding one that is accurate, current one is about a quarter tank off.

Any means of adjustment to correct discrepancy on fuel level?

Is disassembly and cleaning the bar recommended?

Any pointers appreciated.

Anyone with a good one that works for digital dash message me if you want to get rid of it.

I also have heard Nissan made a 2 float replacement for the OEM, is this true.

Thanks

I've not noticed the sheath color, but could be true.

The bar is a huge variable resistor, like a volume knob (potentiometer) and in my experience trying to hit it, and the contacts in the float with some scotch-brite didn't make a bit of difference.

It's submerged in fuel, so very doubtful if it's contamination causing it to malfunction. It's probably just wear. But you could try anyway, it's already broken.

I've been lucky in that i was able to find a original style working fuel level sender to replace my faulty one in my Z with the digital dash.

My other one with analog, i used the revised one with the traditional lever style and it fixed the issue i had with the analog dash gauge inaccuracy.

There was a guy on here (Dafunkmonster) that was trying to reverse engineer and market a updated converter box (DAC) but i don't know if he ever did.

When you say it's a 1/4 tank off, which way is it? Does it show empty and you can only put 11-12 gallons in, or do you go putt-putt with a 1/4 tank still showing?

Fill up, go 20 miles it drops to 3/4. Go to empty, takes about 12 to fill up.

One last question because I don't know how familiar you are with the car. When you say empty, is that because all the green lines are gone, or because it's started it's countdown and it's flashing "E" next to the fuel gauge?

Green lines are gone.
