My gas gauge is stopping at 3/4 of a tank.. has anyone had this issue before?

My mpg hasn't changed and I use top tier gas regularly. Does anyone have any idea what the issue could be?

There's another thread on here, titled, I think, Gas Gauge Issues Thread, in which this issue is discussed by those who have experienced it. IIRC, mostly 2006 and 2007 had the issue, but one or two 2010 said too.

Drop the tank and free up the stuck float lever (or cut a big hole in the floor under the rear seat and free up the stuck lever that way).

Sorry that this happened to you, hope you can find that other thread, and that it is easy to fix.

So, on the topic of sending units and fuel tanks.... has anyone dropped the tank to replace the fuel pump? If so, did you run into any difficulties? How about any advice? I have 226,000 miles on my 07 and I would like to replace the pump on my terms. Namely, not be stranded when it decides to croak. Especially seeing that the tank has to come out to do this replacement. Anybody? Bill

I have.

The challenge is rusty fuel tank strap fasteners. If yours come undone smoothly the rest is straightforward: run the fuel down as low as you can, to reduce weight, support the tank, undo the strap fasteners and lower and disconnect the hoses as per the manual (the "quick connect" fittings are sometimes difficult until you get the knack).

Clean off the top real well so dirt doesn't get into the open tank.

The big "jar lid" unscrews to remove the pump/sender assembly. You may need a strap wrench to get a good grip on it for unscrewing
For re-assembly I recommend a new "O" ring for the "lid", just because.

Check the condition of the "sock" filter on the end of the pickup, mine was like new, but I've seen some posted on here which were in awful shape due to crud in their fuel.

here's a link to another thread on this topic, with links to threads showing how to cut a big, ugly hole in your floor to access it without dropping the tank

https://www.fjcruiserforums.com/forums/maintenance-tech/649066-removing-fuel-pump.html

I found it was easier to simply drop the tank than to chop up the floor. Though, I do gotta admit, it would have been convenient if the access panel had been designed big enough (not sure why it wasn't).
