I've been trying to do some research on this and not found much info. But my thinking is this:
The w213 E63 HpFp has different part numbers to the C63, and is believed to be a higher output pump.
These pumps are very cheap in relation to aftermarket HpFp for example a new Bosch E63 HpFp is about 350gbp for the m177.
Does anyone know if they bolt right on to our C63' M177 as it could be a decent upgrade?
Also to note,
The AMG GT black series is around 730bhp, the HpFp retails from mercedes UK at approx 500gbp with 1 week delivery window, mercedes wouldn't give me the parts numbers, but they would confirm they are not the same part numbers as the C63 as expected.
Would they fit ? Well this can be found by the aftermarket systems if the e63 HpFp kit is different to the C63 aftermarket HpFp the differences will be the same for the OEM hpfp's
One thing you also need to consider is the required calibration for a higher flow system. I did see on an FB group that someone implemented a w213 E63 HPFP and had it calibrated by a tuner - but that is a custom request and should be considered in the overall cost.

Yes this is true, the extra cost of the re map would be a part of it, two things to note. The first being that most people who want a higher flow pump are using it for a mapped car because of a turbo upgrade ect so the re calibration would already be on the table with or without the pump, the second being the extra cost of the re calibration would also have to be added to the expensive aftermarket HpFp.

Most tuners include the cost of calibration in the product cost (or it’s just free of charge).
I would love to pay $1k or $1.5k for a full HPFP upgrade but when talking about a fuel system for a complex and expensive engine, I’m not taking any shortcuts - I want a vetted system.
I’ll see if I can find that guy on the Facebook group that did it with E63 pumps.

Would hardly be a shortcut if a billion pound company use it on their 300k halo car surly. 🤷
So found some more info, apparently it works! Just trying to find out if it's as simple as I'm hoping of just bolt on and calibrate and what flow rates are achieved.
If your looking for a safe 700whp this may be a winner.
Here is the car, waiting for more info. https://fb.watch/jVyrch8595/
Interesting option. I wonder if the HPFPs are physically plug and play with the tuning only requiring the specs of the new HPFP to be input into the software. Similar to coding replacement DI injectors so the ECU knows how to calculate the flow rate.

They are mechanical pumps... so no coding req, just tuning . but the A1770700501 are the E63S pumps, and guess what the C63s pumps are also : A1770700501
Everything I've seen leads me to believe that's correct but I'll confirm on Monday with mercedes, as it's also the fuel pump for the diesel which is strange.
I'm being told that post facelift C63 hpfp is the same as the e63 pre isn't.
Need to do more research into this.
Its bull****, only GTR has another pump part nr , which is almost 100 % certain its also the same pump!
Rest pre fl or FL all use the same pumps.... so its bull****... my AMG tech also dived into this and came to the same conclusion so whoever is telling you this is full of it! so quit wasting money on parts that are already in your car.. the twinscroll turbos is what makes the difference between c63 and e63
Pumps on the pre fl ending on 401 number are the old style pumps.. the newer end on 501... and they supposedly do 20 bar more pressure then the old 401s... ..

Thank me later for all the homework
That's awesome info thanks, can you find any info on the GTR pumps?
Did they do the change in the fl cars or could it be after a build date? I've got a late 2018 pre FL I'll see if I can get access to the hpfp to see part number.
Yes the part numbers are definitely different. Just need to see what part numbers they are.
Would also love to know if the GTR BS has different part number again to the regular BS.
IF we could get the manufacturer part number that would be a massive saving. The e63 HpFp are found in many Diesel cars to my surprise.

Id wish it was 1k or 1.5.. Spool is like almost 5 K
We delved into this and even purchased pumps from e63s and have had FL and PFL C63s in the workshop. All the same pumps.EDIT 2019 AUS model. Seems there is a difference in later model pumps. Thanks for the feedback ...
even with the GTBS I would doubt they are still as high volume as the current aftermarket options which from memory are around a 12mm piston vs the stock 9.xx piston.
WE are working on a cheaper solution, still getting things together on this so no time real soon unfortunately.
There is plenty of VAG upgrade options similar, so I do believe something will be possible.

I’ve done a lot of testing in the dept. on both M177 and M178’s. If you’re a C63 owner, don’t bother looking at any M178 pumps as a “cheap” solution. The bolt pattern and center to center of the mounting flange is much different and wider on the M178.
The M177 pumps all have same flow volumes. It seems the E63 pumps are just updated versions. It’s the same reason why you’ll find that pump on an S580 for example that makes 420hp.

Not true .. on the 178 pumps dont fit a m177 yes.. but not on flow volume... the pre FL pumps ending on 401 do 200 bar max.. the 501 newer type and facelift ones do 220 ...
Even with our injectors ( which are **** ) they use them in all the normale Mercs as well.. its the pumps what makes the difference...
