    I just recently got my 2023 1794 Edition and filled up the tank yesterday for the first time. The gauge showed about 1/8th tank, no low fuel light on yet, but it was full at just under 24 gallons. And that's not just when the pump shut off. I probably added 1/2 gallon after it first stopped. And the gauge shows completely full now. With a 32.2 gallon tank, that’s one heck of a reserve. Does that match what others are seeing?

    Lots of stuff!
    Be careful not to keep running the pump once it clicks off. Fuel can get into the EVAP system and cause all sorts of issues including a stopped engine! There is a thread about the issue of the EVAP and how the warranty doesn't cover the repair which is very expensive.

    Yeah, I’m definitely aware of the risk of overfilling. Being the first fill, I wasn’t sure if the pump shut off prematurely. But the gauge reads full.

    Reserve is 5-6 gallons. I just filled up yesterday with my fuel light on and 15ish miles remaining and put in just over 27 gallons, can't recall the exact amount. I've ran mine to the point I put in 31 gallons lmao, definitely a big reserve but nice to have in a pinch!

    I did. It returned about 5 pages of results with people saying everything from 10 gallon to 1 gallon reserves. And despite limiting the search to gen3, it returns results for older models as well. I’m not wading through all that. There are enough people out there willing to help out a new owner with relevant info. And there are others…

    Lil tip for ya

    From the Gen3 section, click in the search bar at the top right, type in what you're looking for an select those 2 boxes...this will limit the search to that section and show the results as threads only, not every single post with those key words. This search netted me 2 pages.
