Title: Differences in HPFP revisions
Post by: Atreah on October 20, 2016, 09:18:36 am
Hey,

I'm hoping someone could help me with a dilemma. I have a very early MK5 GTI (2005, AXX) and I'm looking for a new, second-hand HPFP. I know VW's revised the pump a couple of times and I'd like to know what the differences between the revisions are and which ones will fit my car? I don't have the actual part number with me at the moment, but I'll write it down when I get home.

If anyone can shed some light on this, it'd be greatly appreciated, thanks!

The main differences are that the later ones have a bleed valve and have changed from a banjo bolt and a hard line to a rubber line with a clip. A google search of images will show you what I mean. It's the left bottom line when looking at the pump from the front of the car. The difference that's of importance to you is the change from the banjo bolt and the hard line to the rubber line with a clip as you'd need to change the line to suit as well.

^^ think the brass hose connection could be removed and the banjo bolt would fit

Ah, I see! Thank you for the reponse :)

Something else I've been wondering, if anyone knows; the reason I'm after a new HPFP is because the top solenoid sensor on my pump has broken.. I'm wondering, if I get a working HPFP, could I just replace the top sensor with the one from the new pump and leave the old pump in place? Or would the new sensor not work with the old pump?

I think the pump and sensor are matched/calibrated to each other some how.

Someone more expert than me will be along soon....

All your aggro makes the Celtemp pump shield thingy look more attractive, even at £25...

The high pressure regulator on top will work from any of the mk5 2.0t FSI GTI's as they are meant to function providing the same regulated pressures.

I have two older hpfp's...my VW tech gives them to me when they are replaced because of cam follower failure. This is an option for you to seek out an old hpfp and swap out the regulator on top with a good connector still attached. But a new one will work if not a problem for you going that route. Just need to clarify if it's banjo or bamboo on the low pressure inlet if swapping out completely...or yes, you can swap out just the regulator. There are no worries when removing it as there are no loose bits waiting to go everywhere when it is removed...it's a solid, everything attached, unit routing fuel in the high pressure chamber to the rail or the low pressure recirculation. See page 9 and 10 of the document: http://www.volkspage.net/technik/ssp/ssp/SSP_334_d1.pdf

Thank you all for the replies and especially the link ROH ECHT!

I definitely have the pump with the banjo bolt, as I recall it being a b*** when I swapped out the cam follower when I first got the car  :fighting:.

All that's left now is to find a second hand HPFP. Found a couple on eBay, though I'm a bit sceptic getting one from there. But I might have to take that route anyway  :smiley:

If shipping isn't too bad from Oregon I would help out and just send you one of the regulators. You can PM me your zip/postal code(←sorry if US zip differs) and I will look into shipping costs for sending one of these regulators to you.

I just had a look through ETKA at work & it looks like the current revision - 06F127025M is compatible on both the AXX (2005) or BWA (2006 onwards) motors.

With the supersession, there are 3 additional parts required to help fit the new pump - 06D133400A (breather valve), 06F133335A (breather valve cap) & 06F127213B (threaded union underneath).

Hope this helps!

Hey! Sorry, did not get a chance to reply yesterday, but if you have one of these lying around you don't need, that would be really great. I'm willing to cover the shipping costs (unless they turn out to be ludicrous) and even throw in a little something extra for the effort!

I sent you a PM with the ZIP code :) Not sure if I can read PMs yet though, so please let me know if you've received it or not :).

I can check on the shipping today and reply to the PM. It's going to just be for the regulator...nothing else.  (revision H, J, or K):happy2:

Indeed, RON was the star in all of this!

I received the regulator about a week after he shipped it, but I only got around to doing it today, as the dealership took their sweet time to supply me with the housing connector which plugs into the regulator itself (which was broken as well).

Anyhow, for those who might be interested; the job is an easy one of course, you just have to unscrew the old regulator and screw in the new one using an adjustable wrench. I did nothing else and the car just worked as it should and performed perfectly while taking it out for a ride.

That being said, if anyone finds themselves in the same position; you can indeed swap your broken regulator with a different one, if you're capable of locating one, thus saving yourself a few hundred bucks that you'd spend on a new pump.

Again, thank you RON for going out of your way and shipping the regulator, you're a star  :drinking:

There are a handful of decent people in this world and I've found a good few on this forum and I wish we could all be like this and make the world a better place to live in. Okay off to have a good ol cry in the corner :sad1:

Good on you guys @ROH ECHT (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=3794)

 @fab5freddy (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=3064) who also sent me a fuel rail sensor that cost just the postage.  :love:

That pressure regulator, as well as the fittings on the bottom, that are not sold separate from the hpfp is why I continue to pop into my VW shop and collect all their used hpfp's. Senseless having to buy the complete pump for one attached item, right? 

I was happy to help out...and I do appreciate the shipping being covered by Atreah (SP  :happy2: ) :drinking:

Happy it's working as my only concern was it being a different revision...and could the limiting valve be changed from one revision to the next? I haven't been able to find where the reason for revisions to VW parts are kept...yet.

Ofc, I wouldn't want it any other way, other than me covering the shipping!

But yeah, the reason as to why you can't buy this item separately remains a mystery to me. Meanwhile, they'll happily sell you the bottom HPFP sensor. I mean, I know they're two different things, but heck, it doesn't look like there are any compatibility issues that would make the production of these as a spare part an impossible feat, even if there is more than one revision. I guess it's just "meant" to be this way.
