2011 they switched to 36 gallon tank for 25/3500.

2010 was 26 gallon for standard bed and 34 gallon for long bed.  

 

2011 was also all the new chassis/frame/brakes/front axle and LML with DEF.

 

 

1500 series are different and chassis cab is different

23 gallons in my 08 Duramax standard bed. :( Or maybe it is 26 when I've used 21 gallons, it says I have maybe 50 miles left to empty.   My former 08 Duramax and 2012 Duramax long bed had a 32 gallon tank.

so no options to upgrade the 2016 1500 trucks?

2016 manual only shows 98L / 26 gallon for 1500's.

 

Aftermarket doesn't seem to do gasoline tanks. 

 

Difference in frames, so HD tanks aren't going do be direct bolt in. 

 

2016 OM:

Fuel Tank
1500 Series 98.4 L 26.0 gal

2500 Series and 3500 Series Standard Box 136.3 L 36.0 gal
3500 Series Long Box 136.3 L 36.0 gal

Going custom is the only way.

 

I suppose anyone could rig up a nice plastic/metal tank under the truck, have a mini pump on a switch that fills the main tank with a feed line into the fuel filler neck. Then vent the small aux tank into the filler neck as well.

Might throw the question around over at duramaxforum.com as well, I recall a few people over there had done some upgrades for fuel tanks before I stopped going to that site due to how shitty of a layout it is now.

2015 LTZ Silverado 2500HD = 36 Gallons

HD frame is massive compared to a 1500.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
