Fuel Filter - 5 micron good enough?

I would think so... The OEM filter at this point is not really used... in fact if you had a 2mic before it I would probably just run an OEM 7mic for possible flow increase.. thou the 5mic Baldwin should meet or exceed OEM flow.

Yeah I have a box of Stratopore 7 mic filters from Geno's I need to use up. I think I'm going that route and putting the 2 mic before the stocker. I'm **** anyway and change filters at 5k along with my oil and oil filter as well.

I put my 2 mic behind the left foglite and my bypass behind the right foglite. Craig

Hello,

I would have to disagree. Only because the heat generated by the coil in the fuel would be dissapated by the mass of the cold CP3 when it went thru the CP3. Pressurization of the fuel will add heat at the outlet of the CP3. I just cannot see the small amount of fuel heating up metal mass as it passes thru as opposed to the metal cooling down the heated fuel mass. Seems like a needle in a hay stack concept to me, but I am new to this.

The CP3 will actually build its own heat based on the pressurization process, which occurs in the pump. The fuel heater in the OEM filter bowl also helps with gelling thru the filter. I dont think you loose all that heat as soon as it hits the CP3, you may loose a little bit of heat at first, but I dont think it will take long to stay warm. If it did I doubt cummins would bother installing it.

Hello,

I agree about the CP3 producing heat. I was checking Fleetguard and the heating element is installed to keep the fuel from gelling(waxing) in the filter. They do not want a flow problem at the filter due to cold conditions. It is not for supplying heated fuel to the engine. As you said the CP3 accomplishes that task.

This raises a concern about the aux. filter setups that do not have heating elements. They are at greater risk of low flow due to cold conditions. There are a few posts that talk about this very thing.

I think that's why an anti gel used in the Winter is a must have. I use a blended 1 and 2 mix along with either Howe's with anti gel or the white bottle of Power Service. In the Winter I have to run an additive because of the lower energy using the #1 fuel or #2 Winter blend. My mileage goes in the toilet if I don't and the power loss is noticeable. The farm store does sell straight #2 in the Winter but it needs a lot of anti gel additive and quite frankly I'm a little scared to use it in -20 or colder weather even with an additive.

Even if its not gelled cold fuel will still flow slower... and the filter would be the choke point... its one of the power limiting characteristics on the Apache in extreme cold.
