cuotfs FINALLY!
Disregard my last message... after I tried to post my last message I was finally able to complete registration and activation.


So i'm glad i'm not the only person who is having this 32gal issue.
I ran my truck down to no miles showing and the fuel arrow pegged and was only able to put in 27 gallons.
I figured they only put the 26 gallon tank in and the additional gallon was the line from the tank to the filler neck.

Maybe I'll try running the truck until it starves then see how much I can get into the tank

cuotfs why the **** can't I register on this site!?
A spammer database cannot be reached to confirm I'm not a spammer so i cannot register.
I put in my cell phone and it sent me a verification code which I put in and still got the ****
message that it can't confirm i'm not a spammer....

Alfredo Garcia Maybe I can help clear the mystery. I had a 2011 Ram Outdoorsman with the 32gal. (as you already know 26 is standard). I had the same issue and was confused. Light comes on, I drive a few extra miles and still tops out at 25.5 gallons. So I did the unthinkable...I ran it dry. I had a gallon for my lawn mower in the bed; got it started and off to the gas station. 32.2 gallons. It was cold out and I figured the fuel condensed slightly.

Many of the concerns of doing this is real. 1. If your area has suspect gas, avoid doing this. 2. If you travel and frequent unfamiliar stations, avoid doing this. 3. If you live in dusty/desert environments don't do this. Impurities, sediments, etc. will settle to the bottom of your tank and guess what gets sent to truck's heart when you get past the last couple gallons? YES, it starts eating the 'yuck yuck'. I was very diligent on my truck and its services. It NEVER failed me. I ran it dry twice. Once for this experiment and once because of bad luck. Older vehicles in general may have pump issues, seal issues, or priming issues. If there is a history of this in your vehicle line then use more caution. 4th gen RAMs don't seem to have these issues but I can't guarantee anything.

So as soon as my light goes on now, I hit the reset on the trip odometer and I know I had another 100 miles to go. I will fill up about 29-30 gallons. That is based on MY vehicle and MY driving habits. I hit a 100K miles on that baby and traded in for a Rebel with a 32 gal tank so I will play a bit and provide some numbers later when I have them.

Today, my light went on for the first time on my Rebel. I immediately pulled and filled. 25.5 gallons. Dash stated I had another 50 miles. Indicators are usually conservative and probably calculated at 12.5 mpg which makes it 4 gallons. Leaving another 2.5 gallon 'reserve'. I get about 15 mpg city. So I estimate from the point my light goes on I actually have 90-100 miles before I whip my phone for AAA. Oh wait, I don't have AAA. Better not test this theory just yet. But based on my experience, the code (NFX), and indicators, my newly acquired Rebel indeed has the 32 gallon.


The 32 gallon is my single most favorite option. It should be standard across the fleet.

jmasters The most I have put in my tank was 29 gallons and that was WELL after the dash said low range and no miles showing on the remaining. But I probably drove nearly 80miles with the light on.

Joshua.rubin09 I am thinking of switching my tank form the 26 to the 32. What do you guys think?

cdeem Has anyone had any luck getting this resolved?

Dano8855 Dealer called today to let me know they spoke to FCA and there will be a software update mid 3rd quarter.

Dano8855 I read on another forum a guy has the same issue. His dealer called corporate to speak with an engineer. He was told a software fix is going to be released in the 3rd quarter.

VaderRebel It's very frustrating, but at the same time not the end of the world. It would be nice if a proper fix was made available sooner than later.

Dano8855 So, I took the truck in for this issue. They replaced the fuel pump/sending assembly. They stated that there may have been something wrong with the original one. I asked, is there a different part for the 32 gallon tank vs. the 26 gallon tank, and they said 'no'.

So, I picked up the truck and the gas light was on and I had a range of 16 miles. I went and filled it up and it only took 27 gallons?

Questions: is 5 gallons the correct reserve?
Why is the range so far off? if the computer says it's averaging 16 MPG, should it be calculating the range by number of gallons in the tank times MPG?

Thanks,
Dan
