Took to the dealership,To check out "random idle surging" , also my stock Dodge seems to smoke more than other stock dodges.
Next day they call back telling me that it will cost a min. $8K to get er' purrin' right. THe truck runs fine pulls trailer fine. But apparently (here is the dealerships analysis): In the filter canister, there is sediment, when ran between their fingers it dissolved, they feel there is sugar in my tank! THey will be installing a new lift pump, fuel pump all new injectors and fuel flush.
THey claim all the injectors and fuel pump are plugged up with this white creamy crap.
I've taken a fuel sample into a lab and it came back saying fine silica and high water.
NEVER once has my fuel light ever come on and I have checked it. We run forestry equip. in the winter and we had fuel lines freezing up alot, (UFA fuel)so at least once a month we changed the fuel filter.

Talking with three other guys with '05 5.9 cummins, (two of them told me their injectors were covered under warranty) All (after my story) open their filter pot drain and recieved VERY similar samples. I've checked and drew samples on the same process and have the same results.

 

If you draw your fuel sample from the drain tube on the filter housing, you'll have a high water concentration because this is where you're draining water off of the seperator.

If you pulled a sample from the tank and had those results, I'd think you were getting bad fuel or lots of condensation in your tank.

 

Sugar in the tank huh? They are charging you $8k for this service?

I think you better look at a different dealership.

I believe that sugar in the tank causing a lot of damage is essentially a myth:

They think you have sugar in your fuel system and they arent going to pull the tank and clean it out? Between the pickup filter in your tank and your fuel filter.....sugar should not be able to reach your Injection Pump. At the very least it would clog your fuel line and filters but shouldnt make it to the IP.

 

Sugar in the tank will not set up the engine and you stated that truck was running OK, just the surging etc. If someone sugared the tank it should stop at teh filter I would think. It should plug the filter if all is working OK. and I would think quite quickly. You have fuel samples so first thing I would do is contact your insurance company and make sure they know you have a fuel sample. Then have their adjuster contact your dealer. If it is sugar I'm sure your adjuster will have his own criteria to have the dealer meet to prove their claim and if not it will prove the the honesty of the dealer and his mechanics and if still under warranty remember poor fuel quality is not covered under warranty. If it could have come from your your fuel supplier he should have insurance for these types of problems also and if you use the same supplier regulaurly and if you think they might be the fault get a sample from your supplier also.

 

RUN from that Dealership.

 

Run, Run, Run....

That dealer is taking you for a racking. $8,000.00 to fix a running engine??

 

i didnt know sugar came smaller than 7 micron! i say drive away from that dealer. they are tying to pull a fast one....little tricksters

brett

 

Looks like Dr.Evil and I should stop by and starting attaching our tow straps to various things on their lot...

Which dealer is it, offhand?

 

Can a another dealership change the crappy dealerships diagnosis? Or would have been reported.
The dealership wouldn't even offer a location of a sample lab they use. It's all visiual?

 

How is one supposed to clean that fuel filter pot out??

 

remove the top. remove filter. open drain lever. you can wipe out as much as you can, lint free rag. the pour clean diesel(kerosene too) into the housing to flush it out the drain valve and hose.

 

For what its worth, that Mythbusters show on sugar in the gas tank was pretty good. The main thing I got out of it was that sugar wont disolve in gasoline (so it shouldnt in diesel). Wonder what it was that "disolved" between their fingers? As mentioned above, it should get stopped at the filter.

 

I think i would have to report that Edit to the local BBB and maybe the local authorities. That's just straight up theft of your money. They should be ashamed of themselves. Just think of all the other uneducated customers that got scammed by them. One rotten apple spoils the whole bunch.

 

The sugar claim has been proven wrong. I've started a new thread forgetting I had this one going. Sorry

Your filter should of caught anything before it ruined the cp3 or injectors . I'd clean out the tank real good, and change the filter, and clean out the filter/water separator real good too. Then I'd fill the tank up with fuel, and without the tube connected to the filter coming from the tank , hit the keys enough times to make sure you get nothing but good fuel from the tank up to the filter assemble. Then connect the line back to the filter assembly, hit the key a few more time to fill the filter, and prey it starts. Sounds like a lot of work, but really it's just an afternoon worth of wrenching. Believe everyone when they tell you their ripping you off. I was a AP aircraft mechanic, and a GM mechanic for most of my life and their ripping you off. How can they tell without bench testing if the cp3 or injectors aren't working, because they said the lift pump is bad too, how would they get fuel to work properly then? see the pattern it's all BS, system just needs to be clean one stage at a time.
