Fuel tank reading fluctuating

[GC34]

Hi I noticed this on my 22 about 3 weeks ago that the gage is inconsistent .I filled up and when I turned it on it read 7/8 full. Next start it read fine at full. Similar happened yesterday, filled up drove a bit and it read 3/4 and now that I started it reads 7/8. Seems like a 1/8 tank error Could it be the E85 gunk build up? Feb-Oct I mainly do E85, Nov-Jan I do ~6 gal of 91 then the rest E85 to avoid the sputtering cold starts.
I'll run a few full 91 tanks and report back

I've got a 22 too. Never had that happen. "BUT" sometimes I think mine burns gas just sitting in the garage. Always run 93....

Run Red Line SI-1 in the tank(s) of premium for a much better clean up than the gas alone will do.

I am also trying to fend off any futures issues by running Stabil 360 Marine in my E85. Cost is reasonable enough to use every tank, and it has some PEA for cleaning/ maintenance. Albeit likely at a much lower dosage than Red Line. Been running this for the last month or two after seeing more and more of these pump failures.

I'll run a few 91s then see if that does it if not I'll try the redline.

Yeah that's my fear that the issues are around the corner, 2.5 yrs of E85 so far
