Fuel Gauge Calibration
I finally got my fuel sending unit installed in the tank today. I pulled up the calibration menu on the gauge and set it to the zero setting. With about 3 gallons of gas in the tank it showed 1/4 tank. With 5 more gallons it showed 1/2. I have a 30 gallon tank.
Question Is it more accurate to calibrate it with a full tank? Does it help to adjust the "pot" on the sending unit? DO they operate linear at all? Or Are they just approximations no matter how they are set up? Cheers, len |
Im not an expert but when I did mine, I have a fuel cell, they told me that the tank needed to be empty.
|
If you have the inductive tube just calibrate empty out of the tank, dip it in a can for the full and set that on the guage then reinstall.
|
You have to calibrate empty and full conditions. Instructions are here:

Thanks Ronbo,
I did the empty, I just need to do the full. THanks! len |
Hi Len, Ronbo,
I'm just getting around to having the bung installed for the sending unit. A quick question, did you install the sending unit on the driver or passenger side top -- or does it matter? thanks Scott |
Scott, you may have to call them about that. I can't see much beyond the bottom of the tank on mine without pulling some panels.
Guess it goes without saying, if that's a weld-in bung and your tank has had gas in it...:eek: |
HI Scott,
It's on the drivers side. If you pull the left rear wheel you should be able to look up on the top of the tank and see the bung, if one exists. THe wiring harness was in place, just wrapped back to the tail light. It wasn't a bad job. Disconnect the fuel and return lines, cap them off. Disconnect the over flow line, loosen the filer tube. Six bolts and maneuver it out. I have an extra set of hands. We also held it on a floor jack until we were ready to drop it out. len |
Thanks Guys,
Mine is an early Kmp so I have to run the wiring myself, no big deal, and the bung needs to get added (which I'm having done now.) Not to worry Ronbo, the fellow that is welding in the bung will take the tank to a radiator shop for a quick dip to ensure all the gas/vapor are gone before any welding... Scott |
I fill up at the hundred mile points on the OD...my ass is usually sore by then. You are welcome.

Ron,
thanks as always for reminding us of the KISS principle. Of course, that would mean that I have to calibrate my odometer too... u going to the roundup? Scott |

If the sender had a float arm (sounds like thats not the case here), you could also use "S" bends on the arm. Of course there's always the tried and true "graduated broomstick" method.:) |
I have the guage but it is sort of crazy. Stays on MT for miles. So- What JAMO said is the answere. Everytime I touch the speedo calibration button for trip reset of what ever- something silly happens- so I don't touch it. I simply drive fast enough so that I do not want to screw around with stuff. All is well.:) :)

I had issues with getting it from a dark background to "regular" background in order to actually see the display. It's fine now, but I'm afraid to touch for fear of messing with the settings.
