Many, many moons ago, I spent an afternoon trying to set up my gas gauge sender to read properly on the gauge for empty and full. The idea was to have it register "4/4" when full and "R" when there was a gallon or so left (30 mile range), just like a real car!
What I ended up with, after removing the sender and re-bending the float arm about a dozen times (no kidding), was when full it would get to a needle width below "4/4" and go no higher. It would then take forever (maybe 40 miles or so) before it would begin to move at all. If I ran it down towards empty far enough it would bounce around both sides of "R" showing me that there was something left in there, but I had no idea how much. It wasn't too bad, though, because I never once ran out of gas on the road.
Yesterday, after returning from a drive and running on fumes as I pulled in and probably needing something to do for an old guy, I decided "THIS is the time to fix that damn gas gauge!"
Trust me.... OCD/CDO people should NEVER do this, because it can NEVER be perfect enough to satisfy them. In complete denial of my OCD-edness, I pulled the sender out of the tank and started the car-guy ritual of bending, trying it out and not getting it right, rebending and re-trying and over and over. I likened it to some sort of perverse Ballet. I must have messed with the damn thing a dozen times and finally, for no particular reason at all and totally out of the Blue, I got this:
This is with maybe a gallon-ish left in the tank.
And this is after I put in 8 gallons (so I guess I have a 9-ish gallon tank):
I looked at that and couldn't believe what I was seeing. I mean..... That's PERFECT! And it only took me a dozen friggin tries to get it right - the second time - So that's what? Only 24 tries?!?!?!?
It's always sumthin with these cars........ But still:
