Mines a 22 and 37's as well. Had no issues for 40k miles and took it on a lot of long distance trips with no issues. Got me through the western part of Canada when I spent 2 weeks up there solo. And then this year when it stalled again and the pump went out, it just snowballed and one thing after another thing. I have a case open with Jeep and starting the buyback process. And my goal is to get a new 23 diesel. Hopefully...
Good luck We love ours hopefully you'll get that new 23
I am running this pump now. Did it myself in November, followed Stellantis (Jeep) recall procedure instructions. 5000 miles since swap, no issues with the pump, and from my research, all of the claims in the add (River City Diesel CPX) are valid. I will fess up if it ever fails. There is no newer or revised pump in production 23 Ecodiesel, and the recall pumps being installed (and still failing) are just original Chrysler Fiat Motor Co Jeep Stellantis original CP 4.2 Bosch High Pressure Fuel Pumps repackaged, using a "new" recall kit number. I welcome anyone with facts or proof to prove me wrong, in fact I dare anyone private owner, dealer, company reps...anyone to provide facts and specifics about the "new, redesigned, improved" HPFP. Again, far as I can tell, there is no such thing.
Soon as I get some money saved up. I'm sending my old recall pump to them.
Depends on mechanical level of experience. The recall procedure instructions walk through replacing fuel lines to left and right side injector banks, and last fuel line which is a pump feed. The pump itself is a rebuilt, precision machined CP4.2 with the filtered (damage control) fuel return kit, (what Ford Super Duty guys have been installing for years, contains contamination if it does fail) and the retainers for the twin cam lifted plungers that pump the fuel are machined in and keep the plungers from rotating out of the buckets during a vacuum or fuel event so they don't clash with the cams and self destruct. This is a direct drop in replacement Bosch CP4.2 (modified per CPX). The biggest challenge is clocking the fuel pump to its correctly timed position when you remove and replace the original (see the procedure in the jeep recall service bulletin on this website). If you clock it correctly using a makeshift cardboard protractor wheel (available on line, at parts stores, sites or a free print out glue to cardboard and make it yourself) aligned as described, it will work. This is similar to timing an old points ignition distributor to get the fuel delivery in time with the cam, crank and each cylinder's fuel event. If you carefully pull the pump note the degree reference as in the service bulletin and install the same, it will be fine. If you are not careful you may have to do a fuel pump retiming procedure which is more CHALLENGING. If you do this kind of work on your own diesels, no problem. If not, maybe get a good diesel shop to do it for you. I am very happy with mine so far. I had multiple stalls, idle surging, codes like many on here po26, low fuel pressure warnings from about 6,000 miles. Parked it for 35 days, researched, tried to get dealer to work on it, do the recall and finally went this way on my own. I am happy with it so far. Good luck.
Too bad you couldn't take this one to the dealer and ask to have it installed to satisfy to recall.
Will you be doing a full DIY writeup?I replaced the recall HPFP with an RCD CPX this past weekend. Although I had new fuel lines, the old ones are working fine with no leaks. I took plenty of pctures. It took me 4 hours, taking my time working slowly and methodically.
Here it is installed before the charge pipe and air filter going back in
Yes mine went out at 4581 +- miles. Waited 45 days for all the parts. Installed and ran for another 50+- miles with no issues. Had the recall done. No issues so far. Switched from Hot Shots EDT to XPD just recently. Maybe one tank so far. We'll see how it goes.
I'm happy to post a bit more. I followed the Stellantis procedure for the most part.
