Less fuel pressure with cdfp v2!!!

it is BS to me because for you to tell me i didnt install it correct, when the internals were clearly failed the first time. due to the fact EVERYONE who got them failed and sent them back, its kinda ridiculous for you to make that statement. also my second time when the worked, the internals failed because the cast peice holding the shins to retain the spring pressure worped to the shape of the spring.

check your PM's and e-mails, more information is on its way.

dude... dont take this the wrong way, but btfu....ya hear?.
these pumps clearly failed because the tolernces were off. he pulled one quote where i had made the comment about cleaning them. and "EVERYONE" didnt fail. well less than 1/2 did. probably more like 1 out of 4. and its been 1 out of 10 since. and... the FACT that you are the only one with a failure after a month says more about your INDIVIDUAL pump and installation, than it does the pumps as a whole. MANY have had these running for 2 months now with no problems. if more than just you eventually has this issue, then we can talk about that then.

these kits, or any kit for that matter need to be cleaned in gas before installation. i have 12 pages of info on the other site where i mentioned that not cleaning them has had an accounted for "some" of the negative results as well. the old kmd, autotech pumps failed because of this... and the new ones fail becuase of this. the general recall was because of tolerances, not user error... ive made that clear..

getting them clean, is just one small issue mixed into a shitstorm of issues with these internal kits. its hard to diagnose and improve the success rates when i have to rely on a hundred different guys installing them and then reporting... its indicative of fuel pumps in general, and when you are sorting out design issues it complicates the feedback you get.

im not full of bs. im trying to be as open as possible about every bit of info i have about these things. these pumps werent/ arent my mother ******* problem, but for the sake of all involved, im trying to take it on to help guys out... and then maybe have a decent, affordable result in the long term.

i had the first working pumps in my car back in 2007... and it took us 3 vw autotech pumps before i had one that worked. these pumps have been a ******* nightmare for 2.5 years of owning my speed. if you dont like it, drop the 667 on the cpe pump.

followed the guides to a T, and ive installed the internals successfully on my buddies car, hes been good for over a month now, install is just fine, i know how important the cleaning of the pump is, hell it is a pump, just like any other pump it needs to be clean when assembled, and when its running. but as you stated in your e-mail, the failure i had with my pump had nothing to do with install.

and as for the first set well hell, it doesn't matter if 1 out of 4 failed, because that means if 1000 kits are sold, 250 people who installed are ****** and have to pull them back out, still sounds like a bad situation if you ask me, the customer. those are dead and gone though, and the issue had nothing to do with your company, never said it did, and ive stated to others that it was not something PG or Debears had anything to do with, they are vendors.

never said you were full of BS, i said your statement was, and so far your statement does not fit what happened to my internals, so making it a general term to say people don't know what they are doing is stereotypical, because so far ive taken out 2 sets of upgraded internals, and had to reinstall my stock one's in there place.

the CP-E pump actually doesn't sound like a bad idea, but due to the fact you cant find one, and they are back ordered it kinda puts it into perspective when you need to move on from a headache as simple as a fuel pump. I thought this v2 CDFP development was going to do it, i guess ill have to see how this third set plays out. the price of a CP-E pump dosent justify something as simple as the fuel pump.

ill keep in touch via e-mail, no need to further clutter this thread.
 
my comment wasnt bs. and that comment i made which was one out of a hundred.....doesnt even relate to your situation. my issue is with the "shock value" of you telling me im talking bs, when im sincerely trying to shed light on what may have occurred, in SOME circumstances.

and yes... these pumps are simple.... getting them to work 100% of the time is IMPOSSIBLE. hitachi warner would scoff at the notion of a "reliable" upgrade thsat isnt flowtested in an ACTUAL WORKING PUMP and flowbench. they would scoff at the notion of people building their pumps in their kitchen with a part where an eyelash of machining or grit can cause failure.

the cpe pumps are clearly superior for that reason alone. and if you dont like it... then fine. buy an internal and know that there are several options out there and those of us who sell them stand behind them no matter what the cause of failure is.

if we can get the rates down below 5% i will be VERY happy. it will mean we are as good if not better than any other on the market. im disappointed that cdi didnt nail it on the first swing.

i have now invovled DCR in the process, and we are experimenting with other softer coatings as well like the other companys use. we are also building a flow bench to hopefully offer cheaper alternatives on full working pumps too. its possible the tian coating was simply to hard and didnt offer the lubricity and sealing properties we would have wanted. the coatings make for more room for error in the tolerance department.

and i do not think this is off track or cluttering the thread. its a fuel pump thread and if you have one or if you want one... i think an open dialogue is EXACTLY what youd want to see with the issues these fuckers have had so far. i encourage anybody to join in with thoughts or impressions!! and in the meantime.. the OP is getting one sent off tomorrow, hopefully with a better result than the first two goddamit:(

i have measured and "felt" a pump that failed, and ive measured it and "felt" ones obviously that hold great pressure. its undectable. tiny particulate can cause failure.... i know for a fact that people are installing these things without cleaning them first, and that causes failure. theres just so many unknowns with an internal kit.

your statement sounded like a general statement to me, and for me to take my time to make sure i did it right, every time ive installed i might add, it does sound like BS due to the fact its a speculation, just like those who thought PG, CDI, and Debears didnt check the products before they sent them out, those people were speculating.

dont get me wrong, i appreciate the products on the market, i appreciate the competition to make the products better, just irks me a bit when a vendor sells you something, it fails, and they point the finger at you when it does when you know it has nothing to do with something you did, it was a defect. it happens all the time, and maybe i was wrong to point the finger back at ya but thats how it stands.

hell if i still had my 2nd set of internals id send em to ya, CDI has them now, but you've seen the pictures.
 
nobody is pointing a finger at you...lol the pumps obviously have issues. he simply pulled one quote out of a 12 page discussion where i was trying to identify ALL the reasons that these pumps "could" fail.
i cant identify if not cleaning them is the cause in a handful... all i know is that between user error, and the pumps themselves, ive been lucky to get 1 out of 4 in use long term. i think the design of these make ANY inconsistency with the tolerance worse than some of the other kits out there.
and that is NOT acceptable.
personally i think the coating more than anything is the culprit, fwiw. we are experimenting with a differnent coating now.

stay tuned, and please dont take my comments personally. i appreciate what all you have had to deal with these kits. its just random musings as i do my best to sort this all out. and impressions from you all here, like at the other forum is much appreciated.
 
I just installed this set last weekend. I cleaned all the parts reassembled and reinstalled. Idled for about 10 min. Checked my fuel pressure with the dash hawk and it was at about 350. I revved it and the pressure dropped to 290. I said Hell No. Waited for the car to cool down and reinstalled stock internals. Now the car idles at 435. Im gonna need a replacement set

that is actually fine idle pressure for idle. i have CPe pumps that do this. the pumps which have problems show them at wide open throttle. what your idle pressure shows has nothing to do with how the kit performs under load. you may not need a replacement set.
 
Idle pressure means NOTHING. It's the pressure you're seeing AT LOAD under WOT conditions that matters. You took the time to tear everything apart, take the fuel pump off, tear it apart, replace the internals, put the pump back together, and reassemble everything...revved the engine once and decided you didn't like what you were seeing so you did the whole process over again?

For the record, my idle pressure was the same or a little lower with the upgraded internals, but is WAY stronger at WOT, where it matters. How many motors have you seen blow up from running lean while idling?

actually the process only takes 30 min. Ill try it again this weekend and run it for a week, get some logs and well see what happens
 
Mommy, Daddy please don't fight!!! LOL

I need to grab some popcorn and see how this turns out.
I have some unused internals for sale if anyone is interested..with high flow spring.
