Re: kz1100a fuel gauge sender replacement, options
28 Apr 2026 04:33 - 28 Apr 2026 04:42I think the "in-line" unit in the video posted will probably do just that as it converts 3 fixed points into a linear output. Ultimately fuel, temp, oil pressure etc gauges are basically voltmeters - that is why temp gauges use an NTC (negative temperature coefficient) sensor so that as the heat rises the resistance reduces and the gauge reads higherBiggest issue with the early bike fuel level sensors and early guages that ive found is they have very little damping. Getting accurate (ish) reading on the guage whilst riding is virtually impossible as fuel sloshing around or surging to the back when accelwrating or front when braking makes the guage needle swing all over the place.
only time mine shows with any accuracy is when stopped on level ground and the bike upright.
Wookie if you can devise a simple retro fit inline circuit between sensor and guage which would dampen the signal id be interested ! Even better if it could be variable.
0 ohm resistence is full on the guage and 100 ohm resistance is empty.
The sender is effectively just an variable resistor in the positive feed to the guage.
challenge set. 🤣
(please move if required, dont want to hijackthe thread.)
The below is calibratable and claims to eradicate fuel "slosh" reactions" ??

I am unfortunately aware on the rarity of these sending units, especially because the used ones are usually junk. If anyone was confused about what sending unit my tank uses, here are pictures:
As of right now i dont really plan on using an OEM replacement because they are hard to find, expensive, and inaccurate (not that i care about accuracy). Unless a good deal on an OEM one shows up, i plan on using an aftermarket sending unit with the fuel gauge resistance converter.

29 Apr 2026 11:56 - 29 Apr 2026 11:57I suggest you check your tank, these are rare second hand and $100 new
The gas tank on my 82 KZ1100A-2 has the six bolt sending unit mounting base with rectangular plastic cover.
View under tank:
KZ1000P unit:
Seems odd both (rectangular and round) mounting bases would be used on the same bike model gas tank...
