As it's nearing time for the fuel filter to be changed on my Diesel, I began researching prices online. As many mentioned it here, gmpartsdirect.com, it was one of the sites I checked (and they seemed to have the best price). In the process, though, I discovered a note saying, "22937279 has been replaced by 23456595."

22937279 was the part number that had been listed in the DIY threads on CruzeTalk. It appears there must be a new part number for the fuel filter, which is 23456595. Does anyone know what may have changed with the updated part number? It seems that some sites are carrying both part numbers and others are only carrying the older part number. On gmpartsdirect.com, they do not have the new part number in stock, and even though it says the old part number is in stock, there's no link to add it to the cart, and it bears a note saying that if you order the old part number, you will receive the new one.

I ordered 23456595 last week (Amazon - $78 with free shipping) and installed this afternoon. The dimensions looked identical to the OEM filter that I took out, and it contained the same O-rings as the kit with the other part number that everyone has been using. The only difference I could identify is that the circle of plastic tabs that goes around the bottom of the filter in the picture at the link above was now a solid circle instead of 6 tabs. Fit was good and everything worked after the initial priming of the system, so perhaps the change to the design of the bottom is the reason for the part number change or maybe it's a new supplier. Either way it works, though, so it seems it is safe to order 23456595 for the CTD fuel filters.

thanks for the link

rock auto has a fuel filter for $20

I saw that when I was shopping for filters, but I wasn't sure if it would be a fit for our Diesels, since it's marked with the EU flag. Usually if something is marked with an EU (or mexican, or whatever) flag, but without a U.S. flag beside it, it means that the part is only for models in those markets. Made me think that maybe it was different in some way, like it might be lacking one of the 3 layers that our filters have for the 3-step filtration. It could fit, but I didn't want to take the risk, so it will be interesting to see if someone else tries it and it works.

Filters are now being produced under the part number 23459023 rather than the two previously-mentioned part numbers.

That number seems to be stamped on the filters, but it doesn't come up in any searches.

I've noticed that too. Seems like the part has been updated, but all of the databases are still just using the old number. Best bet for now, I guess is just search for the 2nd part number, expect to receive the third, and if you can't find the 2nd someday, start searching for the third to see if they've updated the databases to reflect that part number that's actually shipping.
