Cummins Campaign - Fuel Line Support Fix - ISL 400s

[HeresLucy]

I'm posting this on several forums to spread the word.

________


I had read about fuel line failures on other forums that seem to be occurring on '06 Cummins 400 ISLs between 15-18K so we decided to pay to have one added to ours just in case. Would have cost us a couple hundred bucks. Part is cheap but labor is about $90/hr (so I was told).

Anyway - Yesterday I called to make the appt and learned that Cummins has just issued a campaign to fix this. Applicable to a select # of Engine. I don't know the serial # range - but I did ask for the campaign # -- he said 0805. I think he might have just given me a suffix # as I cannot find this posted on NHTSA website. Our serial # 46495122.


Just FYI

Thanks for the information!

I'll take care of linking this to the Cummins engine sectin as well so others will see the info on the campaign.

It is a field campaign #C0805 and reads as follows
-----------------------------------------------
C0805 - (C0805) ISC/ISL CM850 Fuel Line Bracket Installation Campaign for On-Highway Applications
-------------------------------------------------
Must call your Cummins dealer and see if you are covered by campaign and if parts are available.
I'm working to narrow down the SN's involved or at least year.

Thanks for digging into this.

The field campaign covers all ISC/ISL engines produced from January 2005 to December 2006; however, some 2006 engines all ready had this bracket installed at time of manufacture so when you call to check your engine may not be on list. The OEM's will supply Cummins with owner list so they can notify customers but one can be proactive and call a Cummins Distributor and have list checked and work done if needed.

When I first heard about this problem last summer, I was concerned about getting the bracket installed on my engine. The thought of high-pressure fuel from a broken injector feed line spraying all over your hot engine is NOT a happy thought.

I called Cummins and they sent me this fax to determine whether or not the bracket was already installed. Fortunately it was. The bracket is easy to see on the top, of the engine. The pictures in the fax will help you locate it, if you have it installed. (Sorry it's not more clear, but a fax is a fax.)

It sure makes a mess but to degree your comment reflects a concern about fire; there has not been any reports of a fire to NTHSB, OEM's or Cummins as a result of a fuel line break. In addition, Cummins did tests for themselves and NTHSB where they deliberately broke fuel lines and sprayed fuel directly on turbocharger, exhaust manifold, etc and no fire resulted.

In my own experience, I have had a fuel line rupture in a test cell and spray diesel fuel on a cherry red exhaust manifold and not catch fire but it did smoke up the place to a fair the well.

Did watch a 46' Ocean burn up due to a turbo fire(mechanic left oilly rags on the manifold), but as stated diesel fires are rare.

Just checked our ISL-it has the bracket, thanks for info Robin!

Ecker,

Perhaps not. Yet engine fires do occur in diesel pushers, from time to time, for whatever reason. So a "defect" like this one lays heavy on one's mind.

[Ecker]

I recognize its a matter of semantics but its a lot different to say a fire apparently started in or near an engine compartment vs saying it was an engine related fire.

MH Fire

This was posted on RV.NET some time ago -- listen to the end of the video. Who knows if this really caused the fire, but scares me.

While diesel is typically not as flamible as gasoline it is still a fuel and why take a chance. You may beat the odds crossing the street against the light without looking both directions for awhile but the odds always seem to catch up with you. I think I'm not going to play the odds with this fuel line issue nor crossing the street without looking. I have already called local Cummins and scheduled to bring the coach in to fix the defect.

Hey Robin...
Is this the bracket that is in that fax? It is a little difficult to tell looking from that picture...but I think we are ok...

[Sixpack98]

Mama,
That is the bracket. Much better picture than the FAX and should help others identify if they have the bracket.
