  1. Inside the DREADED HPFP

    I thought I would share this with the group. Especially those that are trying to understand the failure of the High Pressure Fuel Pump (CP4). Today I had the recall Z96 done and the HPFP replaced with the "new" style. I wish I could get another new one to tear apart and see the difference. But...
  2. HPFP SIGNS OF FAILURE

    Back in December 2022 I replaced my fuel filter. I noticed metal in the bottom of the filter housing. So I removed the volume metering solenoid on top of the HPFP to inspect for metal. It was in there also. Back then I had a great relationship with the service manager at a local dealership. I...
  3. 2021 JTRD Diesel Fuel Filter (Priming after Replacement) CP4 Damage?

    I have watched numerous YouTube clips of others replacing and priming after replacing the Diesel Fuel Filter. They all do the procedure listed in the owners manual several times 5-10. Some open and shut their door each time. Some wait 60 seconds between procedures. And they still all crank for...
  4. Torque? Gladiator Rubicon EcoDiesel = Hell yes!

    Last weekend I took the Gladiator on a little trip to Moab. I wanted to complete another segment of the Kokopelli trail. This was from Onion Creek to Dewey bridge via the infamous "Rose Garden Hill". With a Mopar 2" lift, 35's, and carrying a slide in camper. Other than kicking out some stacked...
  5. The Rose Garden Hill? In our Gladiator Rubicon EcoDiesel? With a slide in camper?

    We wanted a capable overland vehicle and chose the Jeep Gladiator. Then a custom built Phoenix camper. And the rest has been history. We camp wherever we dare. (No I don't plan on anything this extreme again) If you pick good lines, stack rocks, go slow, it really wasn't difficult for the...
  6. EcoDiesel frame supports??

    I have read that the 2021 Rubicon EcoDiesel has the same frame supports as the Mojave frame. Is this heresy or does someone actually have a reference that it is true?
  7. The fuel mileage just gets better.

    Today we took a drive up over a couple Mountian passes to 10,000ft. We stared with a full tank and just as we were about home I took this pic. ❤ our EcoDiesel. (2” Mopar lift on 35s) EDIT: I was mainly posting this so that others could see the range of the tank. This is the best I have seen so...

    Here is a couple of clips from last winter in Utah. We love winter too!
  9. Bypass Oil Filter System on your EcoDiesel?

    Has anyone installed a bypass oil filter on their EcoDiesel? I have heard they do a great job cleaning up the oil and promoting engine longevity. Here is one I am looking at. There is room down by the engine mounts for mounting the filter. The hose runs would be very short also...
  10. 2021 Gladiator Rubicon real life MPG

    I decided when I ordered my Gladiator that I would document Mileage, Service, and Repairs for the life of the vehicle. Here is every drop of fuel that has been used along with MPG and Fuel Locations. I also Have a Pop-Up camper that we use to overland. I hope this can help a few of you as far as...
  11. Big Sur Overland Trip Pictorial

    We recently had a great trip from Utah along Big Sur. It was still closed due to the slide. But it made for a great camping spot. Next to Highway 1. We love the pop up camper.
  12. HPFP Ticking Noise??? (NOPE "they think" it is the alternator clutch)

    My 2021 Ecodiesel has begun making this sound. I have narrowed it down to what I believe is the HPFP Bosch Pump. There is 11k miles on the engine. Thoughts anyone? It sounds very sporadic. Using a stethoscope I cannot hear the "tinny" ticking sound. Again your thoughts? UPDATE: I had it at the...
