How do I test my fuel capacity?

Is there a reason you don't believe the specified tank is installed.

The OEM tank is a splash over 25 gallons. The light comes on when there is about 5 gallons left. I do not know if the pump will suck it dry, I haven't wanted to find out. The most I have put in is just over 23 gallons.

I just assumed that the light would come if there was only a gallon or two left in the tank. All my previous cars were like that, so I just assumed the same would be true for the FJ80.

I think I'll take the earlier advice and just fill up whenever the light comes on (~20 gal. used)

It is likely an issue of available "range" as opposed to the actual quantity of fuel remaining in the tank. A Corolla goes a helluva lot farther on 5 gallons than a Cruiser does.

I had it in my head that it's around 50 miles or so before you need to get out and push...(no matter what the car is)

Last fill up I went almost 70 miles from when the light first turned on. I was really sweating those last 10-15 miles. I was in the middle of no where and had to get to my favorite gas station!! Curse from my mother...drive 30 miles to save 2cents on gas...Anyway it took 24.XXXX gallons. That is the closest I will take it...

yup, light comes on around 20 per pump filling.

Is there an easy way (read plug) to drain the tank?

Install a 40 gallon aux. and then you won't have to worry about it........

Premium rigs

Most "premium" vehicles build in the generous "early, early warning until empty gas tank" feature. Land Cruiser is such a vehicle. What vehicle manufacturer wants to "taint" their premium brand with running out of gas without a sufficient warning?

Yes, the tank has a drain plug. So does the OEM OZ sub-tank.

I would think ALL manufactures would want to give sufficient warning.

FWIW, I have seen the scary orange low fuel indicator light up early, when only maybe 17-18 gallons are gone (in my estimation), when driving down a steep hill. I guess the fuel sloshes forward, and the sensor is at the back of the tank, because the light would turn off once I was level or heading uphill.

I have taken my fuel needle down to the lowest mark on the gauge, and I have not had the light come on? at what needle point does the light come on?

Question answered previously........

when the needle gets to the bottom line....

[snowwolfwarrior]

I asked, "at what point where the needle is when the light comes on" I can't see an answer to that one in earlier replies.

 

[snowwolfwarrior]

but e9999 has answered my question, well mine has been at the bottom line with no light on, so must assume the bulb has blown. and it can stay blown ...LOL
