Ok i purchased a new cluster(LED conversion gone bad) off ebay with 88k miles on it and car has 92k on it free miles lol...but my problem is that i remember my fuel light coming on like 2-3 lines before the red E...and im at the last line now and the light is not illuminating i want to see if i need to drive more or take it out and change the bulb or wat not..anybody here knows when the light actually illuminates...which line before "E" or watever??

 

my comes on about a line or two before the red "E" line. its not exactly the same every time. i would go through a couple empty cycles before doing anything.

 

If you fill up the tank and see what it takes now- subtract that from 17 useable gallons in the tank
and you will know what you guage reads when it gets low
The voltage may be different to the new guage

usually the light comes on with about 2.5-3 gallons remaining
I average 14.3 to fill it right to the first click of the gas nozzle after the light

 

it works i took it for a sprited drive and it came on talk about being happy i did not feel like taking the dash apart...which is pretty easy im just lazy... thanks for the quick responses..
