Thats right, internals are much cheaper

well as soon as i get them

Beat me to it. Their website isn't exactly clear. Your average muggle probably wouldn't be able to figure it out.

haha, well back to getting internals...i dont get why they would charge the 400 on top of the 667...but internals it is, so KMD or autotech?

the reson why i said 260-280 was because i didnt know the core charge was on top of the 667, but now i know..

[iracer7]

Read this how-to and the Autotech how-to and don't see steps 5, 6, or 7 included in your write up. Why the difference? I'm no expert.

[yetihairball]

I got the fuel pump off the car and took out the internals, but I could not get the OE piston, the part that slides into the 18mm nut, out. That sucker was seized in there and no amount of vice grips or pliers was getting it to come out. I bought this car used so I am thinking that this is not the factory fuel pump. There were lots of other aftermarket stuff on the car that I've been finding over time. The pump holds pressure just fine, but did anyone else have issues taking out the OE piston to replace it with the new one?

I have an '06 MS 6.

[wolly6973]

How do you figure 260 - 280 for the CP-E pump?
It is 600+ and your core charge is 300+ = $1000
If/when you get your core refund it will work out to 600+

Internals can be had for 270 - 400. No core charge...

[Smily27]

so when i go on the kmd website, the internals say for the 2.0t fsi (which is in the audi/vw engine) so im confussed

we have the same internals, therefore we can upgrade our just like them. seems to work out fine

[tnayre]

so after you install the kmd or auto tech internals you can run stage 2 on cobb ap? with just test pipe? sorry for being noobness...

Yes.

OK @Speed3eak, you got me... your thoughts on the Mayan prophecies please.

BTW... THIS IS THE DEFINITIVE FUEL PUMP INSTALL THREAD.

THANKS AGAIN TO THE OP FOR TAKING THE TIME!

[tnayre]

which fuel pump would you like to recommend? protege? they have stiffer springs for 25$ or kmd and auto tech?

I have seen people with good results from both KMD and Autotech.

I've also seen one of the members (@lenny127 ) who has done over 20 installs say that the Auto Tech internals are the nicest machined pieces he has seen.

mod suggestions...

[meelo88]

hummm i'm leaning towards autotech now...the extra $70ish seem worth it for a better track record....

[Smily27]

what about PNP internals from protege garage?

[rghispanic88]

go ahead and try them see how that goes.

[wolly6973]

If you are asking about the PTP internals... GTFO

[AtTheDriveIn]

I've been poking my head around the vdub/audi forums and it seems that those guys are going more towards the Autotechs as a weapon of choice. We all run the same Hitachi style pumo. I've been running them for a couple of hundred miles and they are still pumping like a champ. I get a solid 1900psi WOT. I would stay away from PTP internals. There is a reason why they are cheaper. Their tolerances on machining is very shitty.

[eppopipe]

Im trying to decide between KMD's or Autotechs.
Convince me one way or another.

Start a new thread or search guys. This thread wasn't made to help you decide what internals to get.

[rghispanic88]

^^ what he said. im sure you want me to fuck ur girl/wife for you too right?

SEARCH

Where did you find an 18mm deep well socket to take the stock internals out!?

[wolly6973]

At the store.












Pretty much any hardware store should have em. Got mine at Sears. I had to get a 3/8" drive though.
Make sure you get a 6 pt also.

so far ive checked the local auto stores, kragen, pep boys... even home depot, and they just looked at me and were

[wolly6973]

Kragen is O'reilly right?
3/8 & 1/2 drive...
GM Performance Parts GM8319 - Socket | O'Reilly Auto Parts

[Zbrit00x]

Am i missing something? Thats the one i bought from them and it doesnt get down to the bolt.

[wolly6973]

I don't know since I'm not there.
It is just a spring, you may be able to compress it some to get the socket all the way down?

[Zbrit00x]

im gona go out and try some more, and then go out and hunt some more!

[Zbrit00x]

Found my problem, my bench vice was shit and wasn't allowing me
To put any force on it..., I can compress it and make it fit its just my vice wont hold..

[dgus429]

Good write up bro.. definitly will be using this when i receive my internals

[DingoDave]

Figured I'd share my fail with you guys so others would learn from my mistakes.

Be careful when reinstalling the fuel pump back into the cam housing. You shouldn't have to force the pump back in. Just oil the O-ring thoroughly and gently wiggle the pump until it seats in its place. Then tighten the bolts down and reconnect everything.

Force the pump in like I did and this could happen...





Pinched O-ring. Which led to oil leaking all over the engine and transmission in a matter of a weekend of driving. Fuel pump itself was fine and maintained steady fuel pressures of 1800+ at WOT. Other than the leaking oil, there were no other indications that anything was wrong.

By the way. A new O-ring from the dealership will cost you $13.

I sent you a PM regarding this, but I figured I'd share with everyone.

I was using non-chlorinated break parts cleaner to clean the parts before reassembly and it seems to have degraded the rubber the o-ring's made of. I noticed that the o-ring had stretched and it would definitely get pinched if I try to reinstall the fuel pump. So I wonder if the same happened to you.

Anyway, the part number for this o-ring is L3K9-13-ZE5. I'll be visiting the dealer for a replacement tomorrow.

[rghispanic88]

wheww, man. that was bad. good think it didnt turn out too bad. thanks for sharing.

yeah you shouldnt have to force anything in.

Hey man, think you could list all the tools required for this? It's a great write up I just want to make sure I have everything i need before attempting.

[2010Speed3]

This is what I used:
19 MM Open Ended Wrench
10 MM Socket
18 MM Deep Well Socket
E8 Reverse Torx Socket
Small Flat-Head Screwdriver
1 Zip Tie

and I would say you need a bench/table vise. I couldn't take off the internals (using the 18mm) with an extra set of hands holding the whole core...

^^^ what he said. that 18mm nut on the pump need to be held down. a pair of hands wont be able to hold in place in order to take it out

[Instrument_Guy]

I almost fuct my o-ring like Dingo did when I was re-installing my pump; the high pressure fuel line wasn't lined up properly with the fitting on the pump and it was causing the pump to go in crooked. I pulled the fuel line down, slid the pump in, compressed the spring and started all 3 E8 bolts by hand to make sure every thing was lined up properly

[Smily27]

Should I reflash my ecu with the hpfp map immediately or wait? Just finished my install

Most advise to go easy and break them in for a few hundred miles.
You can flash the map whenever, since you won't be going WOT.

Ok, thanks. I get my tbe Friday from UR. So I just reflash it then

Another question. If my fp were to seize up on me, would I know right away or later? Drove about 10 miles right now and the pressure seems to be holding
