Stock specs are 7 microns absolute (98.7%). Baldwin is 5 microns absolute, and 1-2 microns at 96%. Thats what I run.

 

Anyone have a part number on the Baldwin 5 micron filter.

If I understand this correctly, the Baldwin filter will work on a totally stock fuel setup correct?

 

Yep PF 7977

 

Does anyone know if it will work with a Geno's filter housing replacement lid?

 

Why wouldn't it, that is designed to work with the stock filter right?

 

It will, thats what I use with a Geno's filter lid.

 

I'm using a Baldwin PF7977, 5 micron in the stock filter housing and a Baldwin BF1212, 4 micron spin-on/water separator.

I'm planing on changing the spin-on filter to a Baldwin BF7587, 2 micron spin-on.

 

Al, I noticed your 4 micron is before your stocker. GDP suggests his between the stock and the CP3 but I can't get any info as to why. How has your system been for you? Is it because with just a standard filter they need water separation before it? Does the new filter you are going to have water separation or not?
Thanks.

 

I don't know about the 5 mic dropin but I put the 2 mic ahead of the CP3 and I never heard that engine run so smooth and quieter injectors. I'd insulate the 2 mic if I lived where it's cold. Craig

 

Its just so you can have a staged system and get some work out of the filter in the stock housing. It should also extend the life of the 2 micron filter if it is placed after the stock filter.

Basically the stock catches particles down to 10, 7 or 5 microns depending on what filter you have in there, then everything that it didn't catch will hopefully be caught by the 2 micron.

Placing the 2 micron before the stock filter will catch everything and the stock filter will not catch much of anything at all. Some folks do have theirs set up this way and it works just fine though. I would rather stage them so I can progressively filter the fuel.

 

The advantage to having the OEM filter second is that your fuel heater heats the fuel just before getting to the CP3, if you had the 2mic after the OEM the fuel would cool of before being injected.

 

Thanks for the info. I just don't have anywhere to put the thing in the engine bay so it will have to go down on the frame rail. I'm not too keen on running the supply from the stocker back to the 2 mic and then a long run from there all the way to the CP3. Besides looking clumbsy I don't think it would be advantageous for me at all. Plus, I'm a little concerned about having more of a restriction on the outlet side of my stocker with my FASS pushing 18-20 PSI and then going out of the 2 mic directly to the CP3. I just don't know if it would recover in the correct amount of time for volume. I'm probably overthinking this too much like usual but I like to do things once.

 

That's an interesting point. Using that same way of thinking could be used towards water separation as well I guess. If the heating and water separation are done last before entering the CP3 wouldn't that be the best?
