Just a flag or marker there is another error. Use a actual OBDII code reader.

So the pop off fuel from all 6 injectors will bleed off inside the rail in the head that exits the head at the rear of the engine. Then the second line is the return of the VP44 which is the second line to return to the tank. This is what the square cuts o-ring will seal at the rear of the head. I'm talking the return of either of a FASS or AirDog fuel systems use a check ball and spring to control fuel pressure and flow back to the tank for seperating the air bubbles and fuel excess return is on this line. The fitting in the pump will have a black plastic check ball and a spring.

All I can say is it would be a very rare event to see an extra Quazilla just floating around. I will admit its worth it to get the Quadzilla and do the tuning that fits your driving style.

Dang! If it wasn't for bad luck I wouldn't have any luck at all. Front speakers got installed and hooked up properly for polarity but now my driver side speaker must of come apart in the wiring. Arrrghh! I'm ordering more door panel retainers. 😖

Actually, you can open this up. The return line to the filler neck to the tank is the fitting you remove, and behind that is a spring and check ball. Just be aware the check ball is plastic and could wedge it way down in the coils of the spring. This is why the sudden change in fuel pressure and then later it pops back up when the vibration shakes it loose again. Here is my new spring for Thor. Yes, you are correct, those square cut o-rings are for the return tee in the rear of the engine on the driver side.

Is the check ball getting shoved back into the spring? I typically bend the tail of the coil over so there is a tail tip in the middle of the coil. This will prevent the check ball from wedging into the coil.

We can discuss in a private message.

Thank you.

Yeah, up here in Idaho, we see upwards of -20℉. Automatics up here are rather rare, and manuals are more typical. The guys here are right that you should consider keeping the factory transmission fluid cooler or replacing it with a more modern transmission cooler in its place. The factory cooler has issues with rusting and leaks over time.

A lot of you don't understand why the makeup. I'll admit I fell apart last night; it's Christmas / New Year's again. Both of my bladder cancers came for Christmas. What most people don't get is the fact that what I love to do is out of my reach. Let's roll back the clock and understand that as a kid at the 14 years old I was gifted a socket set (Craftsman) and fell in love with mechanical things. I was building go-karts and mini-bikes with friends. I was fixing lawn mowers and small single-cylinder engines. Then, at the age of 16, I got my Dad's 1973 Dodge Charger SE as my first car. Hence, my nickname came from my first car. Now fast forward to 2002 and buying my first Diesel truck and dove in with both feet into a world I've never done and became an" internationally known diesel mechanic". Now, for 2018 and 2023 Christmas was a lonely and frightening trip to a hospital, and a fight for my life. It's been rather tough to figure out where I'm going from here since my shop is nothing more than a frozen dirt pile today. I have some basic tools to keep things going here, but still missing a lot of tools and equipment. As much as I want to be that diesel mechanic, I can't because of health issues stemming from my kidneys, left side is 82%, and my right is 17% remaining. In this condition a infection would kill me, so I can't really be out and covered in grease and dirt. I can't lift more than 40 pounds because of a hernia risk with my stoma. I want to continue doing what I love, but at the same time, it's nearly impossible to jump into doing major work in Thor to just build articles. It's just too cold and getting difficult for me handle long-term cold without heat and an enclosed shop. Then another realization, Titanium has a birthday and is officially 2 years old. Yes, this means I've been doing daily makeup work for 2 years now and taking my art to the streets. My makeup work was my way of dealing with depression and trying to do something that brought happiness back, while doing something that was very scary at the time, dealing with chemotherapy treatments and the possibility of death. Titanium is my way of finding some enjoyment in my day, as I can't just go down to the shop and fix another problem with a truck, to build a website article is gone. I have to be thankful for the fact that I created the Titanium character to keep me going during a very tough time. Happy Birthday, Titanium!

I typically drive on level 3. I'm not fond of many of the tunes I've seen, as they tend to ramp up aggressive amounts of fuel way too early and try to push the power out. My tuning aspect is more built around daily drivers, milder fuel curves, and main power is up above the 10 PSI or 15 PSI realm, nothing below that.

@Tractorman Those o-rings are square cut and you would need to order from Cummins for replacement. Might be a good idea.

Sorry to hear that. Kind of like myself my mechanic part has to come to end. Lower back is trashed. The ostomy bag is limiting. My knowledge is all there. Just need the body. Hang in there.

OMG! Are you ever going to finish that thing up? Where are the false fuel tanks going? Pretty blue! Blue is my favorite color... Actually fixing my choker collar.

I believe you're experiencing a suction side air leak. Double-check the suction line side fittings, make sure they are snug and clean in the fittings. Let me know what type of hardware you're using. The other part could be that you have a return line leak? Like, possibly a crossover o-ring issue or maybe injector o-ting. Sounds weird, but I've done a head gasket after the head came back, cleaned the baked injector o-rings would weep air in, allowing the system to drain, making a hard start. I've see nthis with crossover tube o-rings as well. Make sure to double-check the return tee in the rear of the engine; it might be weeping air into the system while parked.
