whats the benefit to a stock fuel filter delete?

[Dozerboy]

The factory fuel filter heads are famous for needing to be rebuilt when you're in the middle of nowhere!

Really? Famous? You would think with the thousands on dmaxs on the road we would see post about this daily then... Mine leaked for over a year before it got bad enough I did anything with it. Still the only time I ever saw a puddle its was the size of a base ball in the snow after it sat and idled for 30mins.

I completely disagree. Less parts to leak, less clutter over the valve cover. I understand why someone might want to keep it, but that doesn't mean there's can't be a good reason to remove it.

For most their isn't a good reason, but more power to ya if you want to. They hardly ever leak, and clutter in the engine compartment of a modern vehicle... Pop the hood on any Ford diesel built in the last 10 years!:roflmao: Now thats clutter!

If I was that that concerned I would just mount a filter head and filter by frame rail. I personally think the factory filter would restrict flow a lot and not filter worth a crap at the higher flow rates. Sounds like you guys are running some crappy lift pump set ups if you cant trust your filters.

This is my exact thought. If you're running a better filter on your lift pump than the factory filter how are you getting more filtration. There are plenty of multiple filter setups, but they're meant to go from least stringent to most stringent.

I actually use my truck, and it gets dirty and wet and has to work. I put 40-50,000 miles of nasty roads on my truck each year. You can't over filter these high pressure systems. I'm just stating my experience. I can't afford new injectors every time I find bad fuel. In the boonies you have to run what you have access to. I run Fass Titanium on both trucks.

None..

You provide no good reason or benefit to remove the primer pump/filter assembly. To date there have been 1.5 million Duramax motors built since July 2000 according to the link below. These diesel sites might make up at the most 20% of them leaving the other 80% logging miles with the stock setup...so what is the real benefit as it appears GM did a pretty good job thus far...:thumb:

All it takes is a little condensation on the wrong side of the pump and you can create rust in your fuel lines. The closer you can filter to the hp pump the better imo.

Once again. Sounds like you guys are running junk filters. Yes the factory works great for STOCK applications but is NOT designed for what we do with our trucks.

Yes and GM designed my Duramax for a 1000hp. You're comparing stock to modified. No one is saying you should delete the filter head on a stock truck. When you have a highly modified vehicle there tends to be different reasons behind something then if you have a stock one.

Where are coming up with these junk filters? Who's complaining about filtration here? I'm lost. Why can't the stock filter work in a 1000+hp application? Look if you deleted it thats great, but don't go post misinformation here that makes it sound like it needs to be deleted.

Unless the filter fails in some way you are little to no better off with better filtration when what is stock on our trucks. OTHER then filter life. Micron ratings are Mircon ratings. Hell most of this secondary filtration started with the poor design of the LB7 injection system. In which it has been proven in that case not to make much of a difference. 99.9% of dmax owner are fine with the stock filter/ location. Then there is the rest of you...:hug:

If you read the whole thread, he's talking about the others who have said they had problems with clean fuel after getting rid of the factory filter. I think his point is if you have a better than stock filter installed and you delete the stock filter you can't be worse off.

Read my link above. It takes more then 50gph to make 1000hp. So the factory one is rated 4 micron at 50gph maxx. So after that guess what happens? You loose flow and filtration. I work around this crap all day and have done much research. If you guys think you need a back up filter something's wrong. Most machines we run only have 2 . Not to mention they are in the worst working conditions . So inform me about what you know about stock filters that I don't. :thumb:

Not only did I keep my stock filter head I threw a CAT filter on it, there really isn't such a thing as over filtration for the most part.

My F-ing gawd this what this site has come down to bickering over fuel filters:rofl: Sweet, enjoy fellas:thumb:

Do you really think that just because people aren't on the forums they don't modify their trucks? I see no reason in deleting the factory fuel filter in a stock application as all it can do is help with filtration. However I've seen improvement in rail pressure on modified trucks by deleting it and the hard line and going straight to the CP3. No other changes made.

Please.... Don't remind me. I have a diesel Ford van. Talk about clutter. People wonder why I never move it if I don't have to. I've taken the hpop out three times. That's enough.

Must have been spread word of mouth around the world....

Stock trucks or moderately modded trucks would not see a noticeable difference. Highly modded trucks would see a benefit. If you were looking for every little opportunity to make your truck run better then you go the extra steps to address any poosible advantage that you can get. Good filtration should be your main concern for a truck that you drive everyday and not the performance side of it.

Ya because the Internet is the only way Most of the "older" customers I deal with their only knowledge is based off what's written in Diesel power magazine.
