The rear-mounted filter does more than separate water. It also filters. Actually both fron & rear do some of each ....separate water & filter particulates.

Correct me if I am wrong about that

You are correct, Problems develop (if) it even gets the water it becomes corrosive if NOT drained, if it sits watch out I've cut them open with the inner walls crusted with rust.

IMO its not worth the risk to separate and leave for weeks or even months. If I could spin on a MIC only filter I would and leave the water separating to the engine mounted filter, the entire engine mounted canister is corrosion proof. Don't trust the element in that rear mounted filter to light the WIF icon its way to late when that happens in most cases.

Not sure exactly what you are referring to about the rust. Here is a video of a cut open rear filter/separator.



It appears the filter body is not made of metal that will rust. And I wouldn't be worried about the outside of the filter being dirty. That's the "dirty" side of the filter. I have drained the filter. But never seen anything but fuel (with no water in it).

I personally think that racor unit is fine and does what it should as long as recommended intervals are followed.

If you’re getting rust in your sep either you’ve never changed it, or you’d better find another fuel station! I doubt the housing material would give out like TC says.

 

[TCDiesel]

That's not the correct way to open a filter, Inner rusted Not give out. That filter has seen great fuel. I'll see if I can find picture of one not so good like the ADs.

Again if you want to save some money do it on the frame mounted filter, NOT the engine.

 

[Cummins12V98]

Primary DOES filter why else does my engine mount filter look nearly new at 15k ???

 

[Tuesdak]

JD, what were the filters you asked Genos to add to their lineup?

Good point about the vast quality of parts Rock carries. Been having good luck with Centric and the local chains don’t want to hear about it.

Baldwin PF7977. It was in the suggested item to carry thread awhile ago and it's all over the TDR. like: https://www.turbodieselregister.com...oem-severe-filter-kit-part-68083853ab.254037/

To Genos credit you are one of the few online who do carry the FF5814 - the best filter I can get for aftermarket GDP (Glacier Diesel Products) filter kits.

The other reason the Oldsmobile 5.7L diesel was known as a hand grenade was all the clean and dry diesel fuel we have available all over the USA. We still have dirty wet diesel fuel around just waiting to trash your injection system. All of the Big 3 OEM's have ignored good water separation and fuel filtration for a very long time. This now extends to filter manufacturers like Wix that have reduced the micron specs they provide to say antique diesels like my 6.5TD. Seriously Wix isn't providing a filter good enough for 25, twenty five, year old OEM specs on a low pressure injection engine that can run off really dirty fuel like used engine oil, etc.

@TCDiesel has a point. All it takes is a pinhole for a fuel and air leak. You would be amazed at how fast water will rust through steel, uncoated tanks, etc. Never mind corrosive bugs. I will take the rust through risk over not doing water separation after watching bad wet fuel ruin a complete injection system including the fuel tank to the injector tips. The other diesel fed the same bad fuel that had a CAT water separator on it only had to have the fuel tank replaced. Yes the CAT filter can was rusty as well as everything before the filter element. With the bugs clogging things up the filter didn't last long enough to rust through. The risk of water is even higher with the "do-gooders" dumping Biodiesel into our normal diesel supply. Biodiesel adsorbs water like brake fluid.

Because you did NOT purchase contaminate fuel, I will throw the joker on You 12V ,I ran My engine mounted Filter on My 03 for 5.2 Years and 50K miles, My transfer system with the Zinga Filter I only changed 5 times in the WHOLE 12 Years I owned the truck, The truck Now has 290K miles and He replace the injectors last year only Because I told not to risk it, The engine filter on the 2003 only had 3 filters in 12 years and 147K Miles including the OEM.

My 2013 received contaminate fuel at 213 Miles and it plugged the brand New Zinga with only 3 gallons traveling threw it, This event is well documented at the TDR and CF. The Zinga saved Me 1000s in Repairs. I could post 100s of more pictures, But I can't seem to find the OEM I cut open , it may be on My other Computer.

I seen it all, my banks accounts $$$$$$$ been pump full form contaminated fuel over the decades, I know what works and I know what's Junk.

If you look closely at the bucket fuel , you can see the reflection of the filter head the fuel came from

 

[Wayne M.]

I’ve been spinning filters in a diesel fleet environment for over 30 years. Five of those were on the water in commercial marine. I think I’ve seen it all, and along the way I’ve studied filtration- not scientific like so many great pieces seen here on the TDR, but studying what’s used where, the delivery, the pump systems and so forth. I have never seen a properly engineered filter system allow bad fuel past the final filter in a HD system. The engine should go down on power or quit first via restriction, and I’ve handled Racor 2040 seps that were hourglassed and weighed 10 lbs.
my point here, and this goes back to the OP, Diesel filtration has to be adequate, maintained properly, and with quality parts. The current trucks seem to be good with this, but it’s not cheap. If I owned one, you bet I’d be spinning that primary very often or at least draining it!
I’ve been running CTDs since ‘97 and my personal experience with diesel has been great. I take fuel from hi vol places, spin em every second oil drain, buy the right stuff, NOT looking for a bargain (only a fair deal), and I keep my tank full/ run it down often to keep it clean and free of condensation. I’ve never had a problem. I think I’ve only spotted a few droplets now and again in my drain pans.

 

[TCDiesel]

Wayne thanks for bringing that up , when convenient Keep fuel tank full, when traveling long distances try not to drop below 1/4 tank in hot summer months.

Did you not think of 12V's clicking finger when you posted all of those tiny pictures? THINK OF THE CLINKING FINGERS!

 

[TCDiesel]

Kthaxton, I do have big fingers, what's clinking fingers? I also cannot figure out why it makes double of certain downloaded pic's

 

[kthaxton]

First of all, "clinking" was a typo, I meant "clicking".
I'm taking a jab at Cummins12V98, he always complains when folks attach small images....because then he has to click on it to enlarge it. Since you posted so many small pictures, I'm not sure his mouse clicking finger will survive.

 

[TCDiesel]

Got it,Yay, Sorry !2V.

 

[Newsa]

If 12V's fingers are so retarded, how does he ever change his oil from the top?

I didn't realize baldwin pf9799 was any better than the wix. I wasn't impressed with Baldwin's filter line up because they don't have an oil filter that matches (or beats like donaldson) Stratapore specs.

But thanks for the info

Well, for anyone that does use Rock Auto, they sent me a discount code for 5% off that's supposed to be good until 08-26. The email literally says, "there is no limit on order size or the number of orders... share the code with anyone you know who works on cars or trucks."

I needed a multi function switch Rock Auto had one almost half what the dealer wanted and it has held up better than the original one did. I've had No issues with any thing I've bought from them.
