Ok, I know people on here have said it has no effect on the gas gauge....but.

3times I have gone on long trips. Every time I have filled up with a known 10% Ethanol content, my gauge drifts all over. My local gas station just announced Monday that they would use as high as 10% Ethanol in their gas. I filled up yesterday and guess what..... Gauge is drifting between half and full and it is full.

Any thoughts?

 

I have to say it seems impossible that any liquid would have an effect on your fuel pump float, fluid is fluid. But I can't disagree with you totally. I do know, I have been running 10% ethanol for the last 3 years both in Colorado and California with no effect showing on my gauge.
Don't know what to tell you.

 

Is the float made on to the pump? I know that different floats will float on different densities of fluid. I used to design fuel tank gauges and the floats would be product specific with an additional float for water. It would float on water, but not on fuel. I think my float is just getting so soaked since it is old and the ethanol makes the composition lighter, causing the float to sink.

Either that, or it is just an extreme coinsidence.

If the float is on the pump, I guesss I will have to change it out.

 

Have fun with that. lol

 

Ethanol is bad stuff.
I have been forced to run the fuel as no other is allowed in the
Dallas Tx area.

I have not had any fuel gauge problems.

But have had a loss of fuel economy by 15% combined hwy and
city so it takes 5% more petroleum fuel to burn the ethanol.

My brother would have the fuel gauge drifting problem in his
98 Disco I when he used Lucas fuel injector cleaner, it does not
do it to my 96.

If you can avoid the ethanol I would.
I have much better power with out ethanol.
