Least that's what I read from a GM guy. Nothing but big gassers for him.

Fuel filtration is really a myth??

Pull your fuel filter out and see how long your fuel system lasts. Then you will have proof he is wrong.

Gas at 20-45psi acts a whole bunch different than Diesel at 20,000psi! Water and/or contaminants act like a plasma torch on the CR injectors. Contaminants can cause uneven combustion, nailing, and may even mechanically damage parts. Even as far back as WW I, the Navy realized the importance of filtering their Diesel fuel, especially in subs! And they were mechanically injected Fairbanks-Morse. The Germans used Diesels in "Das Boot" too, but they always had running issues!

Add additional filtering, not less, or..........just take out all the filters and wait for the big bang

Keep it coming fellas. I don't really think fuel filtration is a myth. I'm just sarcastically repeating what that gentleman stated because I think he's off base. I surely think the concept of fuel filtration is real.

Why did unicorns and leprechauns enter my mind???

Comparing gas to diesel in terms of the importance of fuel filtration is like apples and oranges.

Most of your gas sipping vehicles on the road built in the last 5 years don't even have what you could consider a fuel filter. If they do it is in the tank and is not serviceable.

GM pretty much stopped running fuel filters on the gas trucks, cars, and suvs around 2005.

To be fair the guy wasn't comparing gas to diesel filtration. He said he owns a diesel and a gasser and was anecdotally saying that the Duramax guys on their forums go through injectors around 100k ("one guy through 3 sets before 90k!"). So in his mind filtration doesn't matter, just replace injectors at 100k and you're set for another round.

I'm not familiar with GM diesels so I can't comment on that.

Well, GM payed out a ton of warranty bucks on their diesel trucks UNTIL they got smart and installed good fuel filtration . . GM even helped some who did not have probelms until their warranty was done - these were low mileage people who ran out of warranty time.

There were durapukes down everywhere, durapukes ruled the tow truck hook, all that crying probably contributed to floods in the mid-west in those years.

You guy is really uninformed and behind the times, but then, maybe he was not a GM diesel owner during those year models.

And you know like I know that the mods people do have a lot to do with failures of all kinds - are you sure that your guy is smart enough to figure that out as part of his broad/general statement??

Thanks for the heads up on that. I've been searching around looking for specs and requirements for Bosch injectors, GM and Dodge's filtering reqs.


Also, are injectors considered a consumable? If so, at what rate? Is that rate determined by Bosch? Or is there a general age?? The B50 of the ISB is 400k. So that lends some idea. But I'm wondering more about the average owner and how many injectors that can reasonably expect to go through?

Oh well, just thinking outloud.

There is an article on dirty fuel under dodge fuel filters

Hmmmmmmm! They were on to this problem in 2003 and we're still discussing the merits of adding filtration. Its nice to see something in print with references to other empirical data. I'd suggest that the paper be added as a sticky under "One of the First Things To Do"!

A buddy of mine went through two sets of injectors on his Duramax. Two issues where working against him, sub par filtration and using his above ground diesel tank on his ranch.
He traded the truck off for a gasser.

I can say for a fact some of the dirtiest fuel systems I have ever seen are trucks that have an L-tank or something of that nature in the bed. The worst of course being the guys that had no filter on the pump.

I used to use an above ground tank to fill my truck and it seemed like once a month I had to change the filters on the storage tank because they would stop flowing from all the water and dirt that would end up in there.

A lot of people think a filter is a filter. We have been lucky enough to have people educate us to know otherwise. There are several good threads floating around here that prove this. Most dealer techs are not going to take the time to research what filter is best. They are going to install what the parts guy hands him, and I can't hardly blame them one bit especially if it is the OEM filter.
