Hi

I have just experienced my KMD HPFP internals seize up on my car, the garage have removed the fuel pump and checked it over it appears that the piston shaft has dried up in position. This has only been fitted for 5 months and prior to this no issues with the pump, i have checked on the KMD site and it appears that they now supply the kit with MOLY GREASE.

Have any other members had any issues and have you used moly grease to prevent this issue, if so what brand moly grease have you used

Regards

When you originally got your internals, was there any grease in the package at all?

Castrol make moly grease, order some from opie oils if you need it. Im stripping my hpfp down this weekend and swapping internals to a latest revision pump.

Hi mate, no the kit that I had was just the internals it is only recently that they have revised the kit to include moly grease. As I believe normal engine oil drys up due the temperture it reaches, my local vag specialist fitted the kit as per instructions !

I see mine came with grease! Cant remember when I fitted mine but it was about 6-8 months ago at a guess

I bought mine from NAMOTORSPORT on the 12/08/09, and it wasn't supplied with the grease possibly they still had the old kits in stock

Is this something that could be detrimental to the engine or does it go into a safe mode or just unable to run at all?

Around the same time as me then from the same supplier.

Info on APR pump, I have to say im impressed, at first I never bought into the APR marketing machine, but they might be onto something with their HPFP. Might not strip down my KMD pump and just send off my standard one for APR treatment.

I would say yes for several reasons. Here are a few points that I believe puts our design above our competition.

Development with the HPFP starting soon after the 2.0T FSI hit the market. This was at the request of VWoA for use in their R-GTI. After bringing our product to the market, some of our competition simply halted their programs.

We are the only HPFP manufacturer for the 2.0T FSI, besides the OEM distributor, Hitachi, who actually tests the fuel pump before shipping it out to our customers. This even applies to other non VAG HPFP markets using the hitachi design!

We are the only HPFP manufacturer to use a full piston design rather than a stepped piston design, which lesses the chances for side loading and siezure.

A couple of our competitors do not retain the OEM pivoting button on top of the fuel pump, which will increase the chances of side loading and stamping though the cam follower.

We are the only aftermarket HPFP manufacturer that changes not only the piston and bore, but also all of the seals, washers, fastener, and the spring.

The seals have been replaced to lessen any chance of leaking fuel.

The spring has been replaces because the weight of the piston has changed.

The Highest HP members on this board, and the fastest/quickest 1/4th members on this board use our pump. This includes our stage 3 customers, and the 'do it yourself' customers. Sever have switched to our design after having failures with our competition.

To note on High HP applications. Members with the following turbos use our pump: k03, k04, gt28rs, gt2871, gt3071, gt3076, gt35. The highest application is well over 610 WHP!

Volkswagen of America runs our fuel pump and has since 2006.

Volkswagen of Germany runs our fuel pump on their Scirocco GT24 Race cars

We are a TIER ONE Supplier of our HPFP to SEAT Sport in Europe for their motorsport teams

The Three APR Motorsport vehicles have beat the crap out of our HPFP since day one of competition which started in december of 2007! They have never once changed the HPFP and the spare sits unopened in the trailer.

Each and every pump is built in house at APR. The pump is tested before being rebuilt to ensure it's operating properly as to not replace a part on a car that's unneeded. The pump is then rebuilt, and retested again. The pump is broken in on our test pump machine and verified to ensure there are no problems with the pump before it ever touches a customers car. Finally after these numbers are recorded, the pump is serialized and shipped out to the customer. I can even point you to posts where a Diesel HPFP industry insider has indicated our testing procedure matches much of what goes on in their own operations.

My cam follower/lobe (jobby) looked like this when changed in December 2009, and this had been put in new when my KMD HPFP was installed in May 2009 (about 7,000 miles I guess).

Going back up to JBS in the next week or so to have it investigated for a loud ticking which is creeping in further down the rev range each week (started at 6,000rpm, now starting at 5,200rpm).

I'll post up news on here when I have some.

Not sure JBS do KMD anymore, but Autotech. Not sure how they will sub a replacement if that is the case. They will probably lob some grease on mine, tell me it's OK and hope it doesn't seize between now and the end of it's 1 year lifespan!

Mine has been runnig a JKM built KMD pump for almost 2 years with no problems although I do plan to have it checked in April.

Edit - Out of interest - for those with the flat spot, what fuel pumps are being used? Warren, Pov and I all have KMD by the sounds of it, and all have the flat spot.....

Double Edit - I just remember my mate with the S3 with the flat spot has Autotech

I seem to recall JonnyC swapped out his APR pump for a KMD because the APR pump had issues. He may be able to verify....

@ Owen - You got yours fited by Jim, but cant remember if he supplied it or if it came from JKM. I seem to recall it may also be KMD, but it could be Autotech.
