What is the usable fuel amount on the 2dr JL?

LRA (aka Long Range America) makes aux tanks for the Unlimited 4 door , unfortunately not for the 2 Door.

I think the tank got smaller due to the relocation of the aux battery.

When was the aux battery relocated? From where... and to where?

2019 JL 2 door... I'm confident in the 17.5 gallon capacity spec

2019 was 18.5.

You are correct. I was looking at the 2018 owners manual. Attached is the proper file. That puts a monkey wrench in my reserve amounts. I now have about 125 miles of additional range when my fuel warning comes on.

My 2018 Owner's Manual specifies both 18.5 and 17.5 gallons for two doors. I have no idea why, and the spec sheet shows 18.5. I also found a 2018 Owner's Manual that shows 18.5 gallons only.

The 2019 Owner's Manual shows 17.5 gallons, even though the 2019 spec sheet shows 18.5.

Yay for consistency!

The FIRST version of the AUX Battery was behind the Wheel well in the Engine compartment.

The NEW location (on my 2021) has the Aux battery Under the Jeep under the 2nd row seat on the two door near the fuel tank. There is a special skid plate for it.

I don't know what year it changed?

I believe if you have a non-ETorque drivetrain Jeep, only then do you have a smaller aux battery and that is still under the main battery under the hood even on the newest model year. I'm sure someone smarter than me will chime in to confirm this.

The battery under the Jeep with a skid plate is the 48 volt battery that is part of the ETorque mild hybrid system and only comes on Jeeps that have an ETorque drivetrain. In this case you do not get the smaller aux battery under the hood. This part I am confident in, as this is the setup I have on my Jeep.

That's the difference between eTorque & non-eTorque.

Is this actually true about the gasoline cooling the fuel pump? In other words, no one can run their Jeep to a true empty without worrying about damaging a component? That’s asinine, essentially we are not getting the full advertised use or range of our vehicle. Having to constantly stop to fill up is really annoying.

I've read that this is not necessarily true anymore and modern fuel pumps are cooled from the fuel circulating through them rather than by being submerged in fuel.

That being said, I don't think Jeep advertises or promises us any kind of range numbers on anything but the 4xe electric range. I don't think our owners manual says anything about not using your whole gas tank either.

I say go for it!

Last time I heard of a car manufacturer advertising range on a full tank for their car was Bentley setting a 500 mile range goal for the V8 version of the Continental GT, which they did achieve.

That's the difference between eTorque & non-eTorque.

The eTorque starts the engine with a belt using a 48 volt electric motor on the front of the engine that looks like an alternator. That is instead of using the starter motor.
If you stop the engine turns off and then restarts the engine with this eTorque electric belt driven motor when you take your foot off the brake. Saves gas in a traffic jam, and provides a smother start.

It is not a hybrid.

The non-eTorque uses the normal starter motor to start the car.

I hate that I constantly am looking at ways/mods to carry more fuel in my 2dr. What were they thinking? Low mpg car with small tank... WTF!

If someone comes up with an aftermarket replacement tank that holds 50% more, I will seriously consider it.

Not quite a replacement tank, but here's a 2-door aux tank. Long Ranger JL 2Dr - 40L.

It is indeed a "mild hybrid" which seems to have become an industry term and is not limited to Jeep/Chrysler/Stellantis.

Very interesting. Might have to visit those guys next time I am in Vancouver. If that is Canadian dollars it would be even more appetizing. One concern is the robustness and protection. I have belly armor and would need to check for compatibility and ???

Buying stuff in Canadian Fun Bucks* is always nice. I linked to their HD version which includes an "Extra 3mm bash plate". I first read about it on some thread here—too lazy to search right now. I think he said it sticks slightly below the regular fuel tank, so skids might be a problem.

* I refuse to think of any currency that has "loonies" and "toonies" as real money.

Just ain't a lot of room under there, especially considering the safety and the ground clearance unfortunately.
Hell, even the 4xe put the batteries inside under the backseat cause they just didn't have much room underneath without completely re-engineering the entire underbelly of the unlimited.

Edit: That being said, I would definitely also consider a larger fuel tank, if somehow properly done.

Probably not safe or street-legal, but I honestly wouldn't mind giving up my useless rear seats and rear footwell for a larger tank of fuel in that location. Basically just a flat cargo space from the rear to the front seats.

My first car was a Pinto, so I ain't scared of having an interior fuel tank ?
