Recently replaced my fuel filter witch required a partial disassembly of the fuel pump assembly. The fuel filter solved my top end power loss but now I have a fuel gauge that wont read correctly.
In three fill ups since reinstallation it hast read full till ether leaning it over hard in a left hander, hitting a fairly decent bump or major dip. I've thrown it back and forth while sitting still and while rolling neither of witch had an effect.
Once reading full it seems to track fuel consumption like normal, but say at half a tank if you stop and put the bike on the kick stand it will drop down to 1 bar and may or may not rise to 2.
I'm thinking I might have turned the pump assembly a bolt hole but would love your input on things to check before removing it again.

As always I appreciate all comments.

The last pump I worked on had a float system that was about as sophisticated as a toilet. It floated more/less depending on how high the level was. I suspect this is the same?

If it were turned at a different angle, within the tank, it could be binding up , or not rising or falling to the levels it thiins it's supposed to be at. Your idea makes perfect sense. The diagram appears to show the float the front of the tank. Is that how yours is?

Yeah it's a standard resistance based sending unit with a "toilet" float and stubby little arm.

Did you get your filter from Kawasaki, or aftermarket? For a long time, kawasaki never had a replacement filter for their pumps. You had to use aftermarket filters. They were very cheap, aftermarket. I bought 3 of them for 10.00, or maybe less.

Kawasaki did have a filter, but it was for their offroad 4 wheeled machines and it also fit their fuel pumps.

It was from Babbitts and listed for my bike, came with three O-rings and think it was 60.00 dollars. After getting it in I compared it to the ones listed on line and they look identical. I replaced the orings but could find nothing wrong with the used ones.

I've been doing some looking into that and as of yet haven't found just the sender. Babbitts has it as part of the assembly and that is listed for 440.00$ but yes if I could find it and figure out where to get it it can be replaced.

Where do you have the float located? I think it would need to face the front for it to have the full range of motion.

I'm thinking I placed it straight forward, at least I knew it needed to be but at this point I'm second guessing myself.

Can you hold a lit match, or bic lighter over the cap?

No, i have one of those cheap ass pencil cams. Its 10.00 on ebay. It connects to your phone. If the fuel level is low, you might be able to get a look without removing anything.
