That's the fuel pressure regulator with the vacuum hose attached to it. Have you observed fuel leaking while it's running? Any chance it's spraying/leaking where the FPR attaches? I'm not that familiar with your model years rail system. If the two lines above the FPR are leaking and they "plug-in" to the rail there are seals that need to be replaced

FPR shouldnt take more than 5 min to swap out. Even if its cold its an easy job.

Yes it does leak where the two hoses attach vertically in to the fuel rail tube. The first morning that it was noticed a sizable amount of fuel was on the snow. Now just as the picture shows. The pressure in the line does leave the smell linger in the air for some time.

      Oil Consumption

      By Atlas · Posted

      Talk about throwing people for a loop! The newer Jeep 4-cylinders (2018+, "Hurricane" engine) make people think they're hallucinating when checking the oil. A proper oil check, described in the owner's manual, is exactly 5 minutes after shutdown of a fully warm engine. Not before 5 minutes. Not when the engine is cold. You have to take a reading when the recirculation in the turbo and top engine has drained down, but not completely empty.   When those engines are stone-cold, the dipstick reads almost 1.5 quarts overfull. When they're warm right after shutdown, the stick may read almost empty..   If you change the oil and dump out 5 quarts of dirty oil including changing the filter, and refill with 5 quarts, this really can mess with your head if you check the oil later on and don't know what you're looking at.

      Shopping for new truck and have question.

      By stlchevy61 · Posted

      Go for the 10-spd. I have a 2024 3/4 ton and 1 ton dually. We are now at over 100k miles between the two. The 3/4 ton doesn't tow as much and I have had zero issues. The 1 ton tows a couple times a week, 10-16k depending on the machine I am moving. Both trucks are used for construction and also spend time at the farm, have been great. Had an issue with the 1 ton and GM replaced the valve body in the transmission, it was down for 3 weeks which sucked, but it was all covered. It tows great and I really like the 6.6 L8T. Maintenance has been easy, I do all oil and fluid changes myself. The front end is greasible, so make sure you keep everything lubed up.    On our 2018 3/4 ton with the 6.0 I just had to use our unlimited powertrain warranty. I thought the warranty would never actually pay, but once they saw the engine was spotless inside at 180k and the only issue was a failed camshaft bearing, they paid 12k for a new engine. Always thought those warranties were a scam, but if you are diligent about maintenance and keep track of your records, they are great. Many of the oil changes were self performed, but I had all the receipts from buying the oil and filters, and had a log with the mileage I changed it at.

      Recalls 2024 Chevrolet HD

      Alright so this one ended up being a different TSB that was not related to the transmission at all. It was the O2 sensor wire that got too close to the exhaust and melted. I guess the 5v reference wire melted, shorted out and caused about 200 codes to populate and the truck to go into limp mode.    https://static.nhtsa.gov/odi/tsbs/2024/MC-10253570-0001.pdf
