I have been running 2 micron filtration since before 6000 miles. Is this going to extend the life of these finicky injectors? My truck is a 2003 and I don't get any extended warranty benefit like the 01 and 02 owners.

I am 100% sure it won't hurt mine. Later! Frank

Time will tell. I'm sure if there are issues with the 2003's, the General will take care of us!?

Let's hope so. After I heard about the 01 and 02 guys getting extended warranties, I'm hoping that I will for my 03. I added a 2 micron filter, so I hope it helps.

Add some lubrication, pick high volume stations, and you can feel good that you are doing all that you can to ensure your injectors last along time.

Not to be a downer but i added secondary filtration at around 8k and at 25k I had a stuck injector. Now I still am a believer in secondary filtration since there is more to a fuel system then just the injectors and yes I'm going to reinstall the system as well.


It's just really hard to say what causes the injector failure whether it be dirt, bad manufacturing, some type of defect in design, but isn't 300 or less worth peace of mind that you're doing all you can to help your duramax?

IMHO, Standyne Lubricity + Pre OEM Filter is your best insurance. Get about 5 bottles of the Standyne and keep one in the truck so you don't miss adding it with the fuel.

I was talking to a BD tech today because I saw a brief clip about them and the "Intimidator" on TV yesterday and I was asking about DMax injectors.


Their website seems to indicate that they have injectors for the 6.6 but the tech says no.


Are there any aftermarket injectors out yet?

Anything I can do to entertain... http://www.dieselplace.com/forum/smileys/Smile.gif

I was told that all the injectors on the LB7 engines were covered!http://www.dieselplace.com/forum/smileys/Angry.gif


That would explain why I have not gotten my letter and my friend who owns a '01 did.

Nobody has released 'aftermarket injectors' yet, like Mac said only performance based units, and most of them, if not all, are just nozzles in old body injectors.


01-02 and most likely the 03 guys if they have a problem will be covered.


Another thing of interest may be that if you did pay to have injectors replaced out of warranty and do not get reimbursed, the injectors are covered for life. I put injectors in a truck with 211k and at 340k they are bad again, cust is out for the 200k policy and now needs them again, Unfortunately, I cant help him on the initial replacement, but his second set of 8 are on the General.


Truck has no secondary filtration, its an 02 3500. I believe he may use some additive, but not sure on that.

Wouldn't it be better to place a Post OEM Filter in? Oem collects large particles and the better filter cleans out the rest...http://www.dieselplace.com/forum/smileys/Confused.gif

Post OEM would be better, but it appears that will likely void the warranty, most won't go that route.

This is a subject of debate that has gone on since the beginning of adding aftermarket fuel filtration on these trucks. Go here for my approach: http://forum.thedieselpage.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=3;t=005508


I am of the opinion that logically, the best case scenerio would be to have only 2 micron prefiltered fuel get into the truck... so I took the pre-oem route because this is the next best thing. Others have strongly disagreed. There is also the warranty issue to consider.


One thing that seems to be evident though is that post-oem installs seem to have more problems with air accumulation and stalling.


I am at about 63,000 miles with all but the first 8700 running through the current 2-mic prefilter set up and so far (knock on wood) I haven't had any injector problem I know of or any stalling problems but I do accumulate air in the pre-filter. Consequently, I will probably buy the Kennedy lift pump kit when it's ready.


I think the pre-filtration is an advantage to the injectors but of course I can't prove it.


BTW- the current oem fuel filter has 27,000 miles on it and the current pre-filter has 7,000. I'll have pictures of both filters insides when I eventually change them out.

I am somewhat confused...does this mean I am covered for injectors forever? I have 37K on my truck, and am going with the pre-oem 2 mic filter, but it would be nice to know that the injectors are covered no matter what.

Kennedy offers a set of higher flow injectors. I think they are worked over stock units and knowing Kennedy, I am sure they work as advertised.

Here is what he says about them:


*******************************


This modification consists of exchange nozzles set to flow increased volume. The preferred method is to use your existing bodies, and/or injectors. The nozzles flow is improved and matched into a balanced set. The percentage of increase can be varied depending on your needs. The finished set is assembled and DYNAMICALLY tested and matched to ensure all is well and nothing is taken for granted. If done on an outright exchange, a $200 per injector core applies until the cores provided are tested and verified good. These injectors are just too darn expensive to risk acquiring a failed core unit.


"I try to keep a few sets of new injectors on hand at all times. These will be available as exchange units if you have NEW injector cores to send in." - JK


"We could build them for less without doing the final dynamic testing, but I believe that this takes too much for granted. We can also do just the nozzles if you'd like to have them assembled elsewhere." - JK


******************************


He also advertises HP injectors:


**************************************


No muss, no fuss, these are NEW injectors with increased fuel capacity. Basically the same setup as the std HP injectors, only we provide NEW injectors and you send me your cores. Different performance levels available based upon your needs.


"I will be keeping a limited supply on hand. Typically 50 HP units will be most readily available due to popularity. Special orders can take 4-6 weeks so plan ahead!" - JK

Does JK's modification do anything to extend the life of the injector over the factory OEM?
