08 Tahoe Hybrid oil pump

I have a 2008 Tahoe Hybrid with the 6.0L vortec LFA engine VIN code 5. It has about 130,000 miles on it and I am replacing the timing set. Since this is my wife’s vehicle, I’m also replacing many parts that commonly wear out while I have the front timing cover and oil pan removed. After removing the original oil pump and pick up tube, I disassembled the oil pump to check for wear and found, what I would consider, moderate wear (typical for 130,000 miles) and made the decision to replace it. The issue I have run into is finding a replacement oil pump or any kind of “work around” to use an oil pump from another application but after LOTS of research and looking I have found that this particular oil pump is no longer available from anyone and, as far as I can tell, there is no alternate oil pump that will work for my wife’s vehicle.
the GM part number is 12625823
It is a vane type, variable displacement oil pump that was designed and used with the hybrid vehicle and the “typical” gear displacement type of oil pump made for non-hybrid versions of that vehicle can not be used. The GM 12625823 oil pump was only used on the hybrid version for the year 2008. The 2009 hybrid version of the Tahoe uses a slightly different oil pump of the same design but cannot be interchanged with the 2008 part. Not to mention that oil pump is also not available. Starting in 2010 the hybrid Tahoe went to a solenoid controlled variable displacement oil pump which is much larger and has the solenoid built into the pump with a connector that goes through the timing cover so that’s not a viable alternative. I even contacted Melling to see if they have an aftermarket option for this oil pump and they do not. They have oil pumps for the 08 Tahoe but as soon as you specify that it’s the RPO code LFA engine / VIN engine code 5, they do not make anything that would work.
I know I can put the engine back together with the old, original oil pump but then it’s on borrowed time. My obvious choice would be trade it in or sell it for parts but it just had the hybrid battery pack and hybrid controller replaced in the past year and a half and everything else is in very good condition. It’s been a very good vehicle and unfortunately, I’ve found myself in the same situation many mechanics find themselves in, my wife loves the truck and doesn’t want to get rid of it. Any helpful suggestions or advice would be greatly appreciated.
I am putting this in the repair help forum but if it might fit better in some other forum, I’ll gladly repost it there.

This website claims to have this part # in stock.

Thank you for the link, I put in the order right away. It says it was a weekend order and will be processed on Monday, so I’m keeping my fingers crossed. I have put in orders at several different places over the past month but each time I have gotten a text or call saying they don’t have it, their inventory was not up to date and they can’t get it so they cancel my order and refund my money. Hopefully, that won’t happen this time but I’m not even telling my wife yet because I don’t want to get her hopes up. Either way, I greatly appreciate you taking the time to find one for me and I’ll update this post to let you know whether I get the pump or not.

Possible bad news, I got this email from FinditParts:

I’ll wait to see what they do and I’ll post it here with any update but it doesn’t look good. This is about what has happened with every other order I’ve placed in the past month for this oil pump. Anyway, regardless of how it turns out, thank you again for taking the time to try and help.

I'll keep my fingers crossed, for you. 

Thank you.
I did call their office yesterday and was told they were working with one of their fulfillment partners to fill the order and as soon as it gets shipped, I will get a shipping confirmation and tracking number.
The good news is I just received an update and have a tracking number so it is on its way. When I get the pump and verify it is the correct pump, then I’ll tell my wife I found one. I’ll also post the end result here.

Thanks again for the lead and taking time to help.

Well, I know I’m just expecting the worse given how things have gone with this oil pump, but I’m starting to get nervous. The tracking number has been active for two days now and so far it still says they have yet to receive the package. I really hope this one actually exists and will get to me but I’ll keep the post updated.

Damn, now when I search that sight for that part number, it says out of stock. I have a bad feeling that this is going to be another cancellation and refund.

Well, it’s now Saturday and the tracking number still says that UPS is waiting to receive the package. The office for FinditParts is closed on the weekend so if the tracking information still hasn’t updated by Monday, I’ll call them again. I have a very strong feeling it’s going to be another canceled order. I have never tried to upload a video on this site but I have a short video showing the pump and its internal parts. I’m including a diagram from GM to show what the normal gear rotor displacement internals look like as opposed to what is inside my oil pump. Hope this works.

Never mind, it apparently won’t work because it’s an MOV file and I have no idea how to convert it. Sorry, I was hoping to show what my pump looks like inside for anyone interested. Here are some pictures instead.

I don’t know if this will work, it’s the first video I’ve uploaded to YouTube but I’m putting the link here so hopefully anyone who wants to see it will be able to.

Well, I’m glad that I didn’t tell my wife that I may have found an oil pump for her truck. It’s not final yet, they haven’t canceled the order and refunded my money yet but it’s just a matter of time. I received an email from FinditParts on Monday which said:

We’re now able to update the status of your order, number F105308027, with the following tracking number: 1Z5637920392739833. If you have any questions about the new status of your order, you can reply to this email or call (888) 312-8812, and refer to Case Number: 00901960

but when I checked the tracking number, it still says UPS hasn’t yet received the package the same as it has since last week. I contacted FinditParts again to check on it and was told they would look into it and email me with an update but nothing yet. Unfortunately, now when you check FinditParts website for the AC Delco 12625823, it no longer shows up at all.

If anyone knows someone on this forum or any other forum that might have a lead on, or better yet, one sitting on a shelf somewhere I would greatly appreciate it. It can be under GM part # 12625823 or AC Delco part # 12625823. If someone has a new one or has a line on a new one, I’ll be more than happy to pay for it plus any additional shipping to get it from wherever it is to me.
Thank you so much Chad for your help, I’m just sorry it ended up not really being available even though the company said they had it.
Sincerely,
Jerry

You're welcome. I'm sorry that your search has not been fruitful. Good luck.
