Will 2 mic filter hinder oem pump?

I want to install an inline 2 micron fuel filter on my '03 with the oem engine mounted lift pump. Is this doable from a lift pump perspective. Will this restrict the oem lift pump and if so by how much? I will be installing a FP gauge at the same time. Thanks.

I wouldn't do it . Bosch told Dodge to use a 5 micron filter and they settled on a 7 micron due to the "crappy" lift pump setup.
 
I would go with the baldwin, it was designed to meet or exceed OEM flow specs... and it holds more dirt.
 
the oem pump and filter assembly barely provides enough fuel for a stock truck. you may be asking for trouble adding more restriction and/or chip/programmer(i could pull my fuel pressure to zero in stock trim)
 
The combination Fleetguard water/separator, 2 micron filter setup I purchased from Bryan at Diesel Power Products has zero restriction, mounts on the inside of the frame rail in front of fuel tank.



I believe Richard at Glacier Diesel Power has a similar kit, it hangs off the air intake horn.



The first kit pulls, the second kit pushes, I have not heard of either one being a problem. Dave Smith Motors has been installing the same kit Bryan sells on some of their new trucks before they ever leave the lot.

I also have contacted Bryan and he said it would not make any difference. I was wondering if anyone had actually done this type of install only to find out that there was a major restriction. I guess I will have to look into more closely. Also, since the truck is still under warranty the Baldwin is out as it is not on the list of approved filters. When the truck is off warranty I will have no problem installing the 5 mic. Thanks for your comments and suggestions.

My truck is an '06, but I installed the 2 micron filter kit from GDP when I still had the stock lift pump. I ran like this for awhile, and it's fine until you start commanding a lot more fuel from programmers/boxes/etc.

It seems like when I started running the 7 micron in the factory canister (instead of 10), and added the 2 micron, that fuel pressure dropped by . 5 - 1 psi.

I ran that way for awhile, and never had any problems at all.

My buddy's been running a Baldwin 5mc for 45,000 miles now. No problems,but he's not running an FP gauge either. Could quit tomorrow.

DSM is where I ordered my truck from. Great price,great company. However,you must sign a document waivering any warranty coverage on non-Dodge parts. If you take it into their store,no problem. If you're in another state or whatever,good luck. Makes me want to move to Idaho,just to have DSM work on mine.
 
For a couple of years, I ran a Caterpillar High-Efficiency 2 micron fuel filter on my auxillary fuel tank. I could switch between the main tank or the auxillary tank (with the 2 mic. filter). I never noticed ANY difference in engine performance between the two tanks.

Just because the filter has a lower micron rating does not necessarily mean it is higher flow restriction. The characteristic that has a greater influence on flow restriction is the filter media. The best example of this is the flow restriction of the Spatafor oil filter vs. a paper media filter, i. e. lower micron rating and lower flow restriction as well.

If you are going to do a filter, do a 2 micron and add a FP gauge and watch it. Good insurance anyway.



Bosch specs dictate 3 micron or less to maximize the fuel system and not damage the pieces. Anything else is a waste of money unless you can certify the fuel is extremely good.



Keeping your power levels stock or a bit more a good OEM seems to handle it. As others have said, start going to high in fueling and it drops faster.

Yeah... the tech who installed my EB put the solenoid in the wrong spot... they told me to go to the local dealership and have it fixed and send them the bill... well the check showed up today... they are great to work with.
 
I would definetely install a rail pressure guage if you install a 2 micron filter.

No one here mentioned that our injectors are cooled by the excess fuel not used by the injectors that goes back to the tank via the return line. If you restrict the flow you may not have any performance problems as long as you have enough fuel to feed the injector, but if there is not enough to cool the injector you will have failures.
 
A person cannot get enough information and I appreciate everyone's opinion and personal experiences. When I have everything up and running I will post back to let the board see the before and after. Again thanks a bunch and by the way... . go PATRIOTS go!
 
I sell a turf tractor that used a Racor 2 mic fuel/water seperator. They came out with a service bulletin and switched to a 7 mic because they plugged up to quick and customers were complaining of low power. The 2 mic actually filtered the dye out of the fuel. If using a low micron filter, I'd say you'd better carry a spare with you. As long as you get clean fuel, there shouldn't be any problems . Just my . 02.

Exactly, I have Given up on trying to educate People on the Rating systems,5mic or Less absolute will take a 16 GPM pump down to 4 GPM. almost all the filter LABELS are nominal Ratings.
