Motorcraft FL-400s fits, just FYI

[justgotFiSTed]

I know there was some discussion about whether or not the Motorcraft FL-400s filter (just like the stock FL-910s, but a bit longer) would fit, as some people think that the stocker is a bit of a tight squeeze. Just wanted to confirm that it does indeed fit perfectly!

Thanks for the heads up. Should hold a little bit more oil. Anything differs between them inside other than size

Negative. I read somewhere that the 910 that we run is just a shortened 400, and that appears to be true.

Then it seems it would be more beneficial to run the 400s over 910s for more filter media an slightly added oil holding

Yeah, I'm not too worried about it, but figured it couldn't hurt

I know this is an older thread but I though I would add some recently found information.
Just an FYI Picked up a FL-910s and FL-400s today from the dealer. The FL-910 was about $13 and the FL-400 was about $10 (canadian). Bigger and cheaper ?!? What was weird is that the parts guy stated the FL-900 has better filtering (finer particles)... Now I have never been led astray with this dealership so I have to wonder if there is some publication on the filter medium. So I decided to scour the internet and found this:

FL-400S Specifications:

FL-910S Specifcations:
Thread Inside Diameter (in.):3/4"-16
Outside Diameter Top (in.):3.15"
Outside Diameter Bottom (in.):3.15"
Length (in.): 3.36"
Spin-On Filter:Yes
Bypass Valve:YES
Color:White
Burst Pressure (PSI): 250 PSI
Pressure Relief Valve:YES
PSI Relief:14.5 PSI
Micron Rating:50%@35um
Height (in.):3.36"
Seal Outside Diameter (in.): 2.75"
Seal Inside Diameter (in.): 2.40"
Anti-drainback Valve:YES .

In theory the 910 will filter down to 35 micron efficiently 50% of the time where the the 400 will filter to 25 micron 80% of the time. And look at the bypass pressure, the 910 is lower than the 400, meaning in theory more oil could flow around the media if the pressure exceed the bypass valve rating. Not sure what the oil pressure in the FiST is but the 910 is the stock one.

So is the 400 worse? Well not based on the numbers I found (if they are correct). Is the 910 a lower/bad quality filter, very unlikely. So I can save some bucks and use the FL-400S. I may chat with the parts guy tomorrow as the Edge is in for some warranty work.

I know this is trivial but fun to figure out.

Great info. Keep us updated

[HAHAFiST]

So how many quarts total go into the FiST if you use the FL-400S?
