Unknown M809 Filter

[Castle Bravo]

This filter is present on my buddy's M813A1 on the driver's side back of the bumper. I've not seen it before or since on any other 800 series five tons.

Admittedly, I did not look under the hood to see where the lines go to, but the truck is far away from me and I'm now curious.

Does anybody have any ideas?

The label said "Gulf Coast Filters" a Internet search turns up Gulf Coast Filters, Inc. Specializing in Bypass Oil filters, Fuel filters, Hydraulic filters and Custom filtering and they sell bypass filters.
One of the reviews has "Gulf Coast Filters has been a leader in Bypass Oil Filtration and Oil Analysis
for well over 25 Years and has been tested by The US Air Force" Was it a AF truck? Wayne

It was an Army truck.

I've since found out this canister takes a roll of paper towels inside. I think its some kind of air dryer.

Looks like the Racor primary fuel filter on the HEMTT ...sideways mounting is odd. Would make a mess changing element...

The "roll of paper towels" makes me think of my coalescing element air dryers that I have in my shop air system... When they get wet, I pull one set and set them in the sun (or oven) to dry and then reuse them. They look like rolls of brown paper towels...

Of course, a canister with lines running from it could be filtering anything: compressed air, hydrualic fluid, engine oil, coolant, ect. Without seeing where the lines go, or having the part number off the filter, it's very hard to tell...

I'm interested in hearing what it turns out to be, and why it is there...

Air Force gets their trucks from the same place the Army does. That is why you see air froce TO # on those TMs. I've spent Time in both and was a mech in both
