If you use that to replace the frame mounted fuel filter on a 2013+ truck, you’re downgrading the system.

I was looking at the sensor port in the filter mount, as well as Donaldson photos not showing that filter being equipped with a sensor (though the instructions do show a WIF sensor drain that needs installed, so at least that’s good.).

The sensor port must be for a pressure sensor.

I have seen other aftermarket setups put the WIF sensor in the top, so I guessed this was the same.

Yah, the "sensor port" is a place you can put a sensor for a pillar gauge or the like. The donaldsons with wif sensor in the drain plug are really the only viable solution that retains WIF functionality.. The BMP implementation in the line is a joke.

I'm not sure why Fleece selected a shorty filter. There are other, easier to source Donaldsons using that same media with higher flow and dirt holding capacity, just longer. I'm not thinking clearance is that tight to the driveshaft.

Still, you're substituting a $25 filter for a $45 one. Going to take lots of filter changes to come out ahead.
 
Yeah, I just had a WIF sensor on the brain….

Not the filter I would have picked, but I’m guessing they wanted a short filter for driveshaft clearance on all cab/bed/drive configurations.
 
Here's the 1"-14 Donaldson chart I was looking for, if anyone wants to play the game. That donaldson WIF/drain plug, IIRC, will screw into the other models but it only comes standard on a few.

I used P550847 as primary (with donaldson see-through WS drain bowl) on a fass with good success, on my last truck (which was not a 2013+ ram.) P553203 secondary, also with WS drain...with under hood Parker-Racor tertiary with WIF sensor, also with WS drain.

The idea of the looser primary filter has always been to put less suction on the lift pump, which is irrelevant on a 4th gen with in-tank lift pump before both filters. It's also less than ideal because the pump may tend to break up drops of water before they get to the filter/separator. But pump before primary WS is how Ram built it and it seems to work fine.

That’s pretty terrible.

I’ve gotta do some digging, because with the variety of products Donaldson makes, they have to have an equivalent option that works with a spin on adapter

Curiosity is going to get the best of me.

13 micron is not bad, it's just not intended to be the final filtration stage. It's intended to be a suction side primary WS with your FS53000 as the secondary.

You could level the same criticism against the modern FASS primary filter which is a 40 micron gravel catcher and doesn't even catch water on the suction side...as is best practice.

If you want to get all the microns, look at the chart I posted. P5553203 and P553207 (longer) are your options and have been the popular common rail diesel pickup filter conversions for quite some time. Slap your drain plug with WIF sensor on there and you're GTG. I think Donaldson now makes some DBF (blue can) versions in 1"-14 with even tighter filtration but they're spendy and IIRC filter only - so you still need an upstream coarse filter with water separator functionality. DBF5814 for example, 99.9% at 4 micron.

The one upside of a fass/airdog is that they recirculate the tank contents faster than the fuel system return loop. Fuel effectively gets circulated through the filters over and over so you end up doing better than the single pass ratings. Certainly the stock system does this to some degree, but I'm not familiar with the gph of the stock lift pump and bypass.

The stock lift pump is capable of 90 GPH at 0 psi, it’s no slouch. Every drop of fuel that isn’t burned is returned to the tank.

One consideration for the higher flow pumps is many, most/all, of the cross reference filters aren’t rated for that flow. Makes you wonder how their filters do it (especially with a lack of specific specs). All of the fuel gets the full flow and then what isn’t needed to meet the pressure requirement is turned to the tank with the “air” in a separate return line.

I don’t understand why neither FASS or AD can’t make and market a pump with decent filters and accurate data…. Unless they don’t need to because they have enough business on false advertising. At least AD is still using a f/w sep and not a water absorbing filter.

The chart I presented shows Donaldsons in the 100 gph range if you've got the length to accommodate them. That's not an obvious mismatch to what the aftermarket pumps claim to output.

I forget, low side pressure on a modern ram is what, 55 psi? Knowing what the stock pump delivered at that pressure would give a better idea of filter flow and return rate. If it's still in the 90 gph ballpark, that indicates pretty good fuel polishing capabilities with stock filters.

I don’t know anything about the 25+ lift pump for the CP8’s, but the CP3 trucks had an inlet pressure of 7-10 max. Usually 5-7 cruise and 3-5 under heavy fuel use. The CP3 used was more concerned with flow than pressure, so the inlet pressure was acceptable from -5 to + 15 psi per Bosch.

Yes there are filters that accommodate the flow, they just aren’t the ones normally used due to their size.

I’ve been scratching my head for almost 20 years at the poor filter choices by FASS/AD, they simply don’t appear to put any effort into their decisions.
