Yes i know this may sound silly but do i really need a 2mic. fuel filter. I have a 5mic. baldwin in the stock housing. I do trust the fuel station i go to because it is in a industrial park so it sees alot of action at the diesel pumps. i change my fuel filter every 5000. i want to get a water separator but most of them come with a 2mic fuel filter. i found just a water separator filter at glacier diesel products and thinking of just buying that. Any info please.

Thanks guys

 

Consider that Bosch (the maker of your injectors) suggested fuel filtered to 2-3 microns. Least that's what I've heard, still looking for the cite.

Also, thinking about water jet and sand blasting out of the injector nozzle at 23-26k psi. The more you filter the better.

 

Its sad how Bosch wants 2-3 microns but dodge doesnt follow that up with a 2-3 micron filter from the factory. nice. i agree with the more filtering the better. The more i think about this i should just get the 2mic with the water separator.

 

I hate that I have waited this long but the 2 mic set up will be my next mod.

 

Bosch prefers 2um absolute but 5um absolute is acceptable. Anything above they don't like. The Baldwin PF7977 pretty much covers this since it is 2um nominal and 5um absolute.

 

Food for thought: Cummins is the only diesel manufacturer that bucks this trend, specifying 15um for their Class-8 diesels. I haven't been able to find any Cummins stats on their medium duty (ISB-series) engines.

That said, I still think the finer the filtration, the better the life of the engine. Just because a Glock can function after it's been dropped in mud and run without lube doesn't mean it'll last forever in that configuration...same holds true with our engines, and they're a lot more expensive.

 

the kit im looking at is a universal kit 2mic filter with a water separator. both filters are fleetguards. Are fleetguards has good as baldwins?

 

no you dont but 2 mic is nice.

 

I honestly believe the better the filtration the longer the life of the injectors but for well over 200k miles I ran a stock fuel filter....granted it was changed with the oil and oil filter every Saturday morning for 2 years ( had a hot-shot business) and luckily I still have the factory injectors. Crap, I better go find some wood to knock on . Back in March of '08 I upgraded to the AD 150 and have been using (supposedly) 2um Fleetguard filters since and still have had no trouble with the injection system. I no longer hot-shot but I still change the oil and all filters every 3k miles whether they need it or not. Call me crazy but I think good maintenance is the key to this problem. I talked to the guys at DDP at an event and they looked at me like I was crazy for trying to upgrade to higher HP injectors when the ones I had were still working fine. They said "You have 225k miles on stock CR injectors? Whatever it is that you're doing....keep doing it!!" They weren't turning away business, they just couldn't believe I had that many miles and hours on those injectors. Maybe another source for my luck has been the use of PowerService fuel treatment with every tank of fuel from the day I drove the truck off the dealership lot.....I swear by that stuff. I might be jinxing myself by saying this but I now have almost 300k on this motor and although I would love to have bigger stix I think I'll hang on to a good thing until the end.

 

Well heres a question for ya's. i dont tow or race this truck. just simply get to point A to B. i had this truck a year and 3 months now and it has 31000. i put 10000 on it last year. also i use the power service stuff. How long do u think my injectors will last.

 

There again lies the question....how often do you change the filter? Not saying that the fuel treatment works wonders but it does aid in lubricity and with todays fuel standards the CR injectors have to have good lubricity. My local truck shop sells these filters cheap enough that over filtering takes precedence over having to replace injectors.

 

i change it every 5k. but since there cheap it wouldnt hurt to lower that figure compared to doing a injector job.

 

Yep that's my thoughts exactly!! A little money now or a whole lot later!!

 

When I called and talked to Bosch they told my 5um min, so you are covered.

More doesn't hurt thou. I have looked at the specs on all the 2010 OTR Cummins motors and they are all 5um, with 2um over 90% on the smaller engines.

Personally I would get another filter for f/w sep and one for final.. but if you just want a f/w sep you should be fine running that and the PF7977.

Don't over service your fuel filter thou, there are engine mfgrs that advise against it because as a filter ages it filters better and you end up with less effective filtration in the end.

 

is a fleet guard 2um a true 2um? what i think i may do is leave the stock canister in place with baldwin in it and run the 2um and f/w off of that to the cp3
