"Each fuel injector connector tube contains an edge
filter that breaks up small contaminants that enter
the injector. The edge filter uses the injectors pulsating
high-pressure to break up most particles so they
are small enough to pass through the injector. The
edge filters are not a substitute for proper
cleaning and covering of all fuel system components
during repair."

Wonder if this is something Cummins is using to help address injector failure issues?

No pics? That's just not like you Hoot. Where are the charts and stuff? http://www.dieselplace.com/forum/smileys/HiHi.gif

Didn't see any pics of that part of the connector tube.

Well, shucks.........http://www.dieselplace.com/forum/smileys/Embarrased.gif

Wonder what it really is. Never heard of such a thing.


Duramax use it?

I quoted that directly out of the Dodge repair manual. I do not believe Dmax uses it. It's in the fuel supply nozzle exclusive to Cummins. Dmax uses a simple open line.. that corrodes. Little by little we'll get to the bottom of these differences.Edited by: hoot

Ok, can you cram one of those frick'n things in our system?

We want pics hoot!!!! Go tear the truck down and get some for us! http://www.dieselplace.com/forum/smileys/HiHi.gif

The filter is inside the connector tube you see in this pic, feeding the injector. Best I can do right now.

I knew you could produce *something*. http://www.dieselplace.com/forum/smileys/Clap.gif

Hoot, you never cease to amaze me with pictures. What'd you do, rip out your engine and cut a cross-section, then weld it back together and put it back in the truck? http://www.dieselplace.com/forum/smileys/Big Smile.gif

I can very much see a system like that working. The Cummins engine definitely produces enough vibrations on its own (my old 6.5 was definitely a smoother engine than my new Cummins). So then you would need some kind of device/probes that would move with the vibrations causing any contaminants to break down. Yeah, I can see that working quite well. Would certainly help injector life. I'd like to see the internals of how it works.

What happens when the little part goes? Will it stop up the system?

If it's just a grid of sorts, which i'm only speculating, it's probably not a part that moves or wears quickly. If you read the description it says small contaminants. Probably softer stuff. Hopefully it effective in reducing stuck open injectors... like the ones that fill the crankcase. There have been a few of those on the Dodges too but not many.

Hoot,


Remember when you took all those good pictures of the 600 cut-a-way engine? Seems like those that wanted you to see into the future and get pictures of this 'thing', failed. They should have asked you back then.


You're real good but shouldn't have to cover up for the failure of others.

I wonder what happens when it gets all pluged up? I think I can figure it out if it ever did.

I would rather have the feeder tube clog than the injector. It sounds to me like it's an end of the line last ditch rock catcher.

There was talk of rust residue and /or flakes that might come loose from the walls of the main fuel rail in the Duramax system quite some time ago. I believe it is this type of thing... well after any filter, it is designed to capture and desintegrate.

In the long run it would be cheaper to install better lines (OEM) than "add" another potential 100,000 problem....wouldn't it? http://www.dieselplace.com/forum/smileys/Ermm.gif

The device Hoot is refering to does not capture anything at all. It is an EDGE filter. It is a last ditch effort to break up any large particles that made it this far down the line or actually accumulated on the walls and fall off. Pretty ingenious application. I am not sure of the effectivness or long term effectivness, but never the less they are trying.


The Dmax is probally plagued by corrosion/accumulation AFTER all filters. The area from the low pump,high pump, common rail and feeder lines. Can anyone retro 8 separate CAT filters right before each injector? http://www.dieselplace.com/forum/smileys/Wacko.gif

From my understanding edge filters are nothing new. Old Lister diesel engines had edge filters at the injector. Anyone know if the new LLY engine uses edge filters?

Cummins has used edge filters since the ealry 90's in all the B series engines. The 12 valves have them in the injector itself. The 24 valve and the ISBE have them built into the connector tubes because they would not fit in the injector itself after the design change.


The guy earlier was right. They are there to break up any particles of crud that might make its way down the line.


Not a filter at all actually. Just a bad name.

Welcome Don!

I didn't know Cummins has been using them. Matter of fact I never heard of them before, just read that in the manual.Edited by: hoot
