Holy crap my JTRD was build on May 20th 2022. Pretty close. So looks like I should have this "durability improvement". I've also used EDT since driving it off the lot.
Can you explain what a properly primed system is after replacing the fuel filter or draining water?
To properly prime the fuel system you key on the vehicle and listen for the fuel pump tone to change to a high pitch. I do this a few times. The HPFP is not engaged during this process and any air in the lines is pushed back into the tank when priming.
Looks fine to me, those are speed grooves to allow better lubrication.

That image tells the complete full story.... Piston rotates due to aeration / piston sticking in cylinder due to lack of lube / contaminants.
1. The fix to this design IMO is to ensure the piston cant rotate....
ALSO
2. (most importantly) I don't believe a fuel pump should be designed as a life long part.... They should expect failure. A failure should not result in metal shavings touching the injectors... A bypass kit (or proper fuel routing) should route the contaminants back to the fuel tank not directly to the injectors....
Cleaning a tank, replacing a fuel filter should be everything that is required after a fuel pump failure.
It's flat out ridiculous that the pump is designed in such a way that didn't account for failures. It's a pump... PUMPS are wearable items.....
I wouldn't really freak out about this that bad. What ever you trade in for might have a computer, fuel pump, or other electrical failure that would leave you stranded on the highway just like the chance of the CP3 failing.
Yeah yeah yeah. I’ve had the truck for sale so wondering if I can force their hand. Tired of having to deal with dealerships. Anything and everything is pulling teeth and this is just another on the list. I liked this truck but just not happy with the experience after the sale.
100% this. Life is wild, and you and your loved ones could potentially die at any moment. Driving in general, without a CP3 failure is already a really dangerous activity.
Since I don't speak Latin.....had to look that up!
I think the difference here is I didn't spend 60 grand on my shower and I don't expect my shower to suddenly drop through the floor causing the injury. I understand its a comparison but I bought this vehicle and expected it to be reliable. I understand things happen but this is pretty frustrating because there doesn't seem to be any rhyme or reason to the failure. Sure driving is dangerous but you can drive defensively, follow the speed limit, take less busy roads and control WHAT vehicle you drive.
I agree with you, all valid points! Unfortunately all things come with pros and cons, and we just gotta find the best way to work with/around them. It sounds like that's what you're trying to do, so that's great
Even if you include every tile and screw in the shower job, the JT might have more total parts............definitely more different part numbers and different manufacturers/suppliers! More humans assembled it no doubt.
