How much fuel left?

[crazie.eddie]

I was wondering if anyone knew how much fuel is left once the light goes on and stays on? Also, how much fuel is left once the needle hits the orange on the guage?

My mom's Lexus has a nice display giving all that info (Miles left on fuel remaining, Average MPG, Current MPG, etc.). I just like to know in case.

I have an '04 GT.

I can't tell you how much fuel is left, but I can promise you that there isn't enough fuel to properly cool and lubricate the fuel pump.

The gas is the only coolant for the fuel pump. You should never let it get less than 1/4 tank.

I replace a lot of very expensive fuel pump modules for people who could have prevented the failure. They bitch about the repair costs, but don't understand that it is they who caused it.

"Refuel at 1/4 tank."
That should be as common as "don't swear at your mother" and "don't point a loaded gun at anyone".

Is this a common rule with all vehicles? I know I once fueled the Lexus when it displayed 1 mile to get anywhere until I REALLY run out of gas.

Yes and no. Not many cars have fuel pump buried in gas tank, BUT keeping tank full gives less room for condensation to form, so it's not a bad idea in any car.

I'm not sure what you mean by that.
I've not seen a car WITHOUT the fuel pump inside the fuel tank produced after 1988. That means that most all fuel injected cars on the road have the pump inside the tank, submerged in fuel as a coolant.

The PT fuel pump module costs $210 plus installation labor. I keep one in inventory at my shop.
I can tell you that we refuel at or above 1/4 tank, and I've never had to replace a fuel pump in any of my own vehicles. Plus, I've never ran out of gas.

MX5 is right. The fuel that surrounds the pump is what cools it. If you constantly run your car low on fuel it will wear out sooner, and I hate dropping fuel tanks. I always try to keep 1/4 tank also. Another issue is the condensation that forms in the tank. If you start to suck water into the fuel system you will have other problems.

Just this morning I replaced the fuel pump in my sons
88 chevy .Not a lot of fun. the pump,filter and screen
cost 75 dollars Don't have any idea how much a shop would have
charge for labor.I'm going to tell him about the quarter tank
rule.thanks

I guess, whether the fuel pump is inside or not, it's better just to be safe than sorry. I'll make sure to refuel at 1/4 as well.

Thanks
