I'm not saying that it causes all sorts of failures, but, it should be a well known fact that most electrical and mechanical pumps (and other devices) benefit from running at a consistent temperature and from preventing getting too hot... how hot is too hot, I don't know for sure, but fuel pumps definitely fail, and one way to help them keep cool is to not run a fuel tank too low...

I'd still go ahead and fill up at least by the time the light comes on, but you're not gonna harm your fuel pump going under 1/4 tank.

Lobuxracer has posted some pics from TIS showing the system in the past if you wanna search on it.
omg! The search function actually works!

Exactly!

As you can see back in 2007 I was doing the same "OMG! run under 1/4 and you risk killing your fuel pump!" thing because I didn't know about how Lexus/Toyota had engineered around the problem back in 1993... Lance was kind enough to correct me, and I've been paying that forward since

Well if you read the posts in this thread, you'll see that most people are trying to tell you that you don't have an issue. Everything is normal.

I still think there is an issue with it. How come I can pump up to 17 gallon when on E but now I can't. that is my question. I did it before for years but all of the sudden I can't. That is wierding me out.......

Never seen anything past 300 on mine, if you've always been filling up 17 gallons, something tells me you've been letting that tank clean itself to chrome every time.

That is good information, for sure... Both confirms that it is/was an issue, but also that it isn't a worry anymore...

Still no reason to try and use every last drop of fuel...

NO! This is the worst way to do this.

Read. Learn. Stop doing bad things (unless you're a masochist.) See 3. (a) (2).
