Gasoline gague reset
First and formost I want to say thanks to those in authority on this forum and for the veterans that answer questions. You guys rock...plain and simple.
I have a 2000 ranger with a 2002 motor and transmission. A 2000 computer with an 02 harness. (A Heinz 57 for sure). All is well and worked out except my gas gague. It does have a 2001 cluster I picked up at pull a part. The gas gague was not accurate so I topped off the tank and set the needle at the "F" mark. However it is still not accurate. How do I set this? TIA

1989 and up Fords use a fuel level sender/float in the gas tank that shows 16 ohms when empty and 160 ohms when full
Fuel gauge is calibrated for that, on any 1989 and up Ford including Rangers
There is a anti-Slosh module on the back of the cluster that was a common failure on Fords, its a separate module plugged into a slot in the cluster, no wires attached
When these failed fuel gauge may show empty all the time or full all the time or even be intermittent
Since you have moved the needle manually the fuel gauge would no longer be calibrated to the sender, not sure what you can do about that
On the back of cluster there will be a yellow/white wire on pin 12 of the 12pin connector
That's the wire to the fuel level sender, test it with OHM meter
Unplug that connector
Set OHM Meter to 200ohms if it has that selection, if not then just OHMs
Ground 1 meter probe to cab bolt
And put other probe on the yellow/white wire, this is OHMs so no polarity, red and black don't matter
You should see between 16 and 160 ohms in display if sender in the tank is working
Rock the truck, so gas in the tank sloshes around
OHMs should go up and down as the float in the tank goes up and down
If all is well then sender to cluster wiring is OK
Plug all wiring back in to cluster and turn on the key
The OHMs you saw on the test should correspond to level shown on gauge
88 ohms is about 1/2 tank
124 ohms about 3/4
Problem is its not truly linear, the float is at the end of an arm, so its not exact except for full and empty and for empty there is usually a "reserve" of 2 gallons, also not exact
Anti-slosh module
You can try another one from wrecking yard, many Ford models in similar years used the same module
1996-2003 Rangers used the same clusters
Or you can bypass the module to take it out of the circuit, Google: Fixing Gas Gauge on 95-2002 Ford (read discrption)
Watch the video
This is only if your gauge was acting oddly before your adjustment
