Alright stop trying to get your damn post count up. You're a straight up loser troll. You answered you question. No one here knows what the minimum amount if gas the pump Will suck. Go run yourself dry and let us know. Your post suck just like you. Later troll, im unsubsribing from your ignorance. Im going back to landscaping my yard. Peace.

Just fill up at every gas station you see and you will be fine.

No need for the thread to turn nasty/disrespectful.

This thread cured my herp.

I think the question "Can the fuel pump access the same amount of fuel the sending unit can?" is a legitimate one. Purely academic of course but an interesting question nonetheless.

My non-specific academic answer is NO: the sending unit is a float on a stick with a full range of motion. Empty is when it hits the bottom. The fuel pump sits slightly above the bottom of the tank as it is equipped with a sock pre-filter. As soon as air hits the intake it will stop sucking fuel up. How much fuel can remain before this happens I don't know, it will come down to whether or not the bottom of the tank is level, etc.

My practical answer to the question "How much fuel is left (so I can guess how far I can drive)?" is this: You have no idea how long your fuel pump will last without sufficient cooling before it burns out and stops working completely. So don't do it. When you see that light come on you should already have a plan to get fuel. Don't end up stranded.

Salad,
You could be a rocket scientist!
So assuming the tank is level, it sounds like the sending unit could access all but a negligible amount of fuel. The more dramatic limiting factor then is the space at the top of the tank.

That is interesting. What is the most you have ever been able to get into the tank? Assuming you stop when the pump clicks off the fist time. (I have heard going past this point can cause problems)

Jeeez....I've been a supporter of the thread but...... I also have wondered in a general way about the answer to your question but, as salad says, it really has virtually no practical value.

I know this is not what you are asking, but GoJeep has an article on how to increase the fill capacity of the standard 20 gallon tank to around 25 gals IIRC. He says that applies only to metal tanks and I am not sure when they switched the XJ to plastic tanks.

And keep an eye out for the Troll Hunters! Those guys are professional and relentless and will wade through almost anything to get their quarry. I shudder to think of the consequences of a full fledged frontal attack.

This must be the very first car you have ever owned. EVERY car made is designed this way, if this can't be absorbed by that thick brain covering you have.


WHEN IT GETS TO 1/2 TANK

FILL IT UP !!!

THEN YOU DON"T HAVE TO WORRY ABOUT ANY OF THIS...

This^^. Thanks, Fred.

The practical value of the information lies with being able to fuel plan as accurately as possible. This is important due to the nature of vehicle that we drive, as where we go there are not always filling stations.

From the dailey drivers perspective I am sure many of the forum members here have driven their XJ until the gauge read empty, and when they filled up probably asked themselves why their 20 gallon tank only took 17 gallons when they had been driving on empty for awhile.

I've driven mine on empty while sneaking my way to the gas station. First time I ever held my breath that long. Didn't pay attention to how many gallons it took, just how much the meter said I owed.

Now, I wait until the needle is just above, and not on, "E" before adding a few bucks worth.

Edit: The reason I only put a couple bux worth in the Heep tank is that I'm on a fixed income and I must divide my funds between the Heep tank and beer. I never run past 6 full beers remaining before filling up again - just to be on the safe side you understand.

Fantastic advice Ken. Very pragmatic. I will keep this in mind.

I pretty much understand the nature of the beast -- as of this month I've been driving XJs for 29 years.

All XJs (with the possible exception of the last few model years) have the same physical size gas tank with the fill capacity artificially limited with plumbing. This plus other normal variables that others have mentioned mean that there is no conceivable way that anyone can generalize about that last fraction of a gallon which might or might not be in your particular tank. I wish you luck If you are going to depend on this for your next off-road trip into the wilderness.

Calculations bearing on having an adequate supply of beer, on the other hand, are much simpler: Decide how many gallons you could possibly need including the down time when you are out of gas and then double it. If you are on a fixed income and can't afford enough ice, just make sure your itinerary takes you near cold streams to cool the precious liquid (beer, not gas). Been there, done that.

Forgive me for rambling. Beer and Jeeps go together and my doctor says I can no longer partake of an important half of that equation.

I will add a note, no doubt boring to the assemblage but bearing a slight relationship to the thread: At the dealership the salesman was taking us around to look at what was arguably a completely new concept in motor vehicles and the absolute very first thing he proudly pointed out was the little holder for the gas cap on the fill door. My wife the sports car driver rolled her eyes at that but what she couldn't believe was that the 5-speed models weren't available with a tach while the automatics were. We bought one anyway.

Yep. Tons of forum members are responding to this stupid ****, aren't they?

Where are they?
