While there are two decent filter choices for the OE filter canister on the 3rd gen (OEM and Baldwin) I wanted better filtration. Bosch would like to see 5 micron filtration on the CP3 and injectors and Dodge only supplies 7. The Baldwin PF7977 is 5 microns, but I still wanted more.
After hours of research online and with filter manufactures I decided on adding 2 additional filters to my system. I added a Baldwin BF1212 on between the tank and the OE filter bowl and a Cat 1R-0750 between the OE filter bowl and the CP3.
Why these filters.
The BF1212 is a 20 micron absolute (97.88% actually, so not quite absolute), 4 micron nominal filter that has fuel/water separation ratings of 97%-99% efficient for removing free water and 92%-95% efficient for removing emulsified water. It is the cross reference for the Fleetguard FS1212 (20 microns at 95%, 10 microns at 79% and 90% for both free and emulsified water removal), but is cheaper and offers slightly better initial filtration. This is my first filter and is more than adequate for initial filtering and f/w separation.
The Cat 1R-0750 is a 2 micron absolute (old data) or 4 microns absolute (new data) final fuel filter. It is rated the best in its size/series of any of the like filters. (Fleetguard FS5320 is 5 microns absolute (old data), and the Baldwin BF7633 is 7 microns absolute (old data)).. The old vs new data is simply a change in measuring filter efficiency. According to the new test standard 4 microns is a good of a measurement as you can obtain, thou nothing is physically different on the 1R-0750.. so I say it’s a 2 micron filter as most people are familiar with that style of reporting. The Donaldson P551313 is also rated at 2 micron absolute, but the Cat is easier for me to obtain.
Mounting:
Both filters are mounted on Baldwin FB1311 filter bases. The BF1212 is mounted to a piece of steel that uses longer driver’s seat bolts and one time use nuts. To tap into the OE steel fuel line I used 3/8 compression fittings and 3/8 push-lok hose.
To mount the Cat 1R-0750 I used the GDP MK2+ Big Line Kit as the starting point. I ordered the kit without the filter base, filter, and fuel pressure sender “T”. The GDP kit was complete and easy to install.
At the same time I also replaced the banjo on the inlet side of the OE filter bowl with a high-flow banjo from GDP. All my fittings are now high flow.
Baldwin PF7977: In the stock fuel canister I am running the Baldwin PF7977. This filter is rated at 5 microns absolute and 1-2 microns nominal. It also has fuel/water separation ratings of 97%-99% efficient for removing free water and 92%-95% efficient for removing emulsified water.
Pressure:
Because I am now running 3 filters on the stock in-tank LP I wanted to get a gauge on my setup to ensure I am not starving the CP3 of fuel. I installed a Pricol 0-30 psi electric gauge between the OE canister and the CP3. At idle I see 9 psi. (From what I gather most folks running a stock setup see ~11psi at idle). I attribute the 2 psi loss to two things, one there is some increases restriction from the filters but I feel the largest drop comes from the big line kit and hi-flow banjos. Because the elec fuel pump always has the same flow, based on constant voltage, and that pressure is directly related to flow/resistance I think the decreased resistance from the big line kit and hi-flow banjos has dropped the pressure, thou the flow is the same. Off idle I have yet to see below 5psi of pressure, thou I don’t run lots of hp and haven’t towed with the setup yet. But for my needs I have adequate fuel pressure, thou I will upgrade when/if the OE LP fails.
If you need more flow I recommend the setup like I have with a AD Raptor 100 plumbed between the BF1212 and the OE canister. The BF1212 is actually a vacuum filter and will act as a good pre-screen for the LP, and will catch any water before the LP emulsifies it. This setup could be used with the stock 3/8 line for stock-mild hp, or with ½” line and a larger LP for high HP.
Personally I don’t recommend deleting the OE filter bowl. 2 reasons. 1 is the WIF sensor (yes I know its mediocre at best, but it’s better than nothing) and 2 is the fuel heater. 2 microns is a tight filter, so I like to know that the heater is there.
