Spare FPCM (Fuel Pump Control Module) WISE IDEA!!!!

When I go to order from Summit racing and put in my year/make/model, it shows me part number 13565641 for $72.99. Now when I search the Summit site for just the part number that works for you all 13554821, it shows it for $33.99
Will either one work? My vehicle is a 2025 Yukon XL, which has a larger fuel tank than a Yukon. Does that matter? Can I just get the cheaper module?

So the 4821 module had been the most up to date part number as I last understood. But since you have a 2025 model, I would hit a number of the GM parts sites online and verify for sure there have been no changes for 2025. I just plugged in a 2025 Yukon XL Denali in gmpartsonline.net and it indicated if did not fit the 2025. Many sites will accept the VIN as well, so I would probably seach a few sites to see what comes up.

If you find the 2025 has a different part number, please update what you have found. Fuel tank size should not make a difference for the control module, it could and used to make a difference for the in tank fuel pump on older models.

It may be possible the 4821 module has been updated again as well?

You might want to crawl under the truck and find out what module part number is on your truck as well just in case some of the GM parts catalogs have not been updated for the 2025 models yet.

Sounds like the one ending in 4821 may have been superseded or compatible with MY25+ only.

All the previous ones up to it were the following: 13537053, 13544060, 13544950, and 13545846.

I've seen where a new model year won't have 100% of the parts ready for order online. It is like the bill of material isn't fully available.

According to EPC, Electronic Parts Catalog, the part # for 2025 is 13560984. It looks to be a new part and there is no parts history for it. I don't think the others will work in its place.

Sometimes parts get superseded because improvements are made - but sometimes not.
Nearly always, when a part number gets 'updated', it is seen as an opportunity to increase the price,
whether or not any improvements were realized.

I have a neighbor that will be taking delivery of a very recent build 2025 Yukon Denali XL next week, I will try to check the module part number on his and see if the connector looks similar. It was in transit from the TX assembly plant last week.

I would be VERY careful with part numbers/application from a place like Summit Racing because we have no idea where they get their data from and how up to date it may be.

If there is a new part number for the 2025 models, it may be a totally different module, or it may be a new design or vendor based on past problems and maybe the superceded part number trail has no caught up yet?

This will be interesting to see what change(s) may have happened with the 2025 models as they start to get into members hands.

Update, I just got under a very new build of a 2025 Yukon (2/2025) and the FPCM part number is in fact 13560984 as jerry455 had listed above. What I do not know is if the 13554821 module has been superceded by the 13560984 and if they are interchangable.

Seems that the 13560984 show up around $60 on some of the GM parts sites.

We may need to wait and see if the GM parts catalog is updated to show if the 13560984 supercedes the 13554821 module.

The module location on the 2025 Yukon is the same as prior years, in general the module and connector looks pretty much the same, however, I did not disconnect the connector and inspect or compare the connector in detail.
