Fuel filter condition monitoring

[ENafziger]

I'm still interested in this topic, so please let us know what you do and how it turns out.

Simply install a single fuel pressure guage after your last filter and before the CP3 inlet. As long as you can maintain a safe positive pressure at the CP3 inlet under WOT, you're fine

I have issues with the water in fuel sensor wires with the B20 kit. If it's a damp day out or you hit a puddle just right you get the light saying that you've got water in the fuel, there is none just that the sensor wire has gotten wet and it's a false signal one of these days I'm going back to Dodge and have them turn it off so I can remove the 2nd sensor and wire. That said the filter is not a ByPass typenor is the stock one on the engine so if you monitor the pressure after both filters you can run them as long as you have good flow and pressure with out fear... .

I packed the plug on my sensor plug with dielectric grease. I have had no problems with the filter sensor. (also did the sensor on the factory filter)

I installed the 5psi low fuel pressure light, from Cummins, at the INLET of the factory filter. As long as I am delivering the 5psi to the factory filter, any problems after the factory filter is the dealers problem. If you don't rember, I installed 2 B-20 kits. The first has the fuel water seperator and the second is the 2 micron Fleetguard filter. (yes AH64ID, I have read your posts on fleetguards 2 micron filter)

I would move your gauge to the outlet. A plugged filter will not show up on that light and you could do damage that would be on you, not Dodge.

As per Chrysler, any changes, additions, or modifications to the fuel systems factory filter or after the factory filter will void the engine warrenty. So, I have no choice but to install the pressure switch befor the factory filter.

That is like claiming analog gauges (boost, EGT, etc) interfere with the computer and will void the warranty. Its total BS.



I guarantee if you plug the filter with a bad batch of fuel and and run it so long it hurts something warranty wil NOT cover the damage. I have already had issues where bad fuel plugged the filter so bad cruising fuel pressure was dropping under 3 psi. Without a gauge at the CP-3 I would have kept on until either the engine quit or damage occured.



Your truck to do as you please, but, if you think Dodge will honor a warranty for bad fuel you are mistaken.

Like cerberusiam said, your not really doing any good and any issues that arise post your psi sender will not be covered under warranty.

Yep... and they won't warranty if Modified also, or will the Insurance company in some cases, Thats Why I support Auxiliary filtering. You don't have to worry about the Insurance company or Dodge. Just got the return Call form customer In OH, Exploded his CP3 ( I am in West Yellowstone MT) last Monday, Mention He just Purchase NEW Bosch Genuine Injectors 3 weeks earlier, I said Pull them and test, Yep all destroyed, Done, ruined, and Yes he was running 2 spin-on filters with Pressure gage, He said his running pressure was 12-15 and it Never dropped. He will be dropping his Tank and cutting open the filters this weekend,I will give updates,I also will leave the ugly Details out.

Cerb. . I agree on the BS.

Sorry, what factory engine warranty? As soon as you delete the exhaust or you add any other component on to the engine this could cause the warranty to be voided. I do know about the Magnuson-Moss Warranty act.

In all my years of owning a vehicle (over 45 years) I have never had any major component replaced under warranty. When they usually fail the component is out of warranty by 1,000 miles or more. This is call design obsolescent.

Nah, gives us the uglies as well. Truth is truth.

The only thing I changed out on my truck is the factory muffler and tail pipe with a Banks cat back system. We have emission testing in N. E. Ohio. They plug into the port under the dash and look for codes and programer footprints. They also look under the truck for the catalitic converter. So I have kept my truck stock. I have always made my extended warranty money back on warranty repairs.

I don't understand how the 7micron factory filter on my truck can plug up when it's fuel is supplied from a 2micron filter? Please explain this to me.

Is that in writing somewhere?

I don't think the dealer will give me that information, but I will ask.

What warranty??... isnt my warranty out on my truck??? isnt it 5/100K on the engine?

Besides, bone stock or not, if there is anything beyond a single injector failure, the stealership will blame it on bad fuel and say no warranty anyway!!. . And that really doesnt matter whether its a Dodge, GM, or Ford... they all do it.

Reading on these various forums makes it sound as though there are millions of gallons of bad fuel watery fuel out there being sold to the general public. ??

In my job, I sometimes work on diesel engines from 6L common rails up to 175L common rails... most of which, using bulk fuel, off road fuel, rig fuel... etc... and have not seen the fuel issues. Been doing this job for going on 15 years... . I just do not see it... The only injector related failures we have been having were directly related to the new 6. 6L CR engine and people still trying to pre-fill the spin on filters!!!. . Even though there are two different stickers on the filter base saying DO NOT PRE-FILL!!!... .

Maybe its bacause the engines I work on have the fuel filtration systems designed and installed by the same manufacturer that designed the engine??? Not Bosch saying one thing, Dodge doing another???

Wingate. . Your right on the #s, I mention several time in several different posts, its the 1% you need to worry about. Bosch as fas I know has NOT change... its the process thats flawed,You have the Power plant builder, Bosch as the Injection Maker, Dodge the final installer/seller, then the end user, the process can get watered down,Example Cummins want to sell motors, Dodge want to sell trucks,Bosch want to make the best injection system,they have NO responsibility to the final seller,only the power plant builder who wants to sell,Now the seller wants only minimum filtration and components,the seller cannot re-tool its plants to install the additional filtering components plus the $$$$, Now Bosch will Make $$$$ BC the seller installed minimum filtration which will be good 99% of the time. Dodge sold How many CR 2003-07 200,000?

The engine is sold to Chrysler with the fuel and oil filter on it. The poor fuel filtration is a Cummins issue that Chrysler got stuck with.

Every time you fuel you run the risk of getting a bad tank of fuel, no matter where. Period. Millions of gallons is about right. In reality the bulk of the fuel we buy is substandard for an HPCR system. That has been proven over and over.

The engine is sold to Chrysler with the fuel and oil filter on it. The poor fuel filtration is a Cummins issue that Chrysler got stuck with.

No. Cummins sells an engine with no warranty to Dodge with a configuration that includes the filtration per Dodge specs. There are better filters and filtration available but not with the cost parameters defined by Dodge and Cummins.

It shouldn't, but you don't know with the location of your psi sender.

They won't because there is nothing that says it, at least in all the searching I have done. Nothing even requires you to keep the OEM filter canister on the truck, but you better meet the min OEM specs.

It's Chrysler spec'd filtration. The non Ram ISB's have different fuel filters. Bosch still spec's a better filter than Ram has.

Simple solutions will be continually Ignored in America. How about a magnet in-case in the Fuel tank molding, How about mandatory correct filtering on ALL retail pumps in America,Most retail Diesel Pumps in America have the same POS filters (China Made Junk) that they have on the Gas Pumps Rock catchers.
