so far I can only find the 1R0770 and 1R0771 water separators from CAT and it looks like the numbers have been updated. All of them have 1"-14 threads
advanced efficiency
326-1643
ultra high efficiency
364-5286
and another number 326-1644 but I think its one of the above filters...
josh, did a little research and came up with the 1R-0770 being a radial fuel water seperator from cat with a 98% efficiency at 10micron but it has a 1"-14 thread which puts it with he same mount as the 1R0749 2 micron filter. Quite a bit larger than the airdog...
here are a few good pics...
They have a clear pvc hose at any parts or hardware store but it will fog up from the diesel after a little use.
Wouldn't hurt for testing, but the fuel up there doesn't move much unless your wot. You really need a closed loop to simulate high flow to see the true effects.

That adapter is awesome!
I'm not sure which cat filters are water seperators too but i don't think any are going to be low Micron with the water seperation feature. I'll research what I can.
You have moisture problems or just wanting to keep the system as pure as possible?

Yes, you are correct on what to do. How much you have to grind on the mount can vary. Screw the filter up and check the clearance.
But be sure to keep the working area clean!! The shavings will deystroy your injection system.
As far as the little tabs inside the filter seal on the base...
Running 2 stroke oil at 1oz per gal every fillup and my ballance rate spread is within 1.0 across the board at 98k miles. I'll keep running it, can't hurt...

1R750 doesn't have the water seperator according to mustang cat in Houston. The guy wasn't much help other than that.
Have to go through inventory at a smaller dealer, this place won't let anyone near there inventory. And most of it is stack sheveral rows high on pallets. Huge dealer...
Could be that the 759 was replaced by the 751. Not sure. Have to ask cat
The 749 is huge! And it has a 1.25 thread (something around there)

Check it out. The 751 is quite a bit longer and bigger diameter than oem AD.
Keep us posted. Maybe there is a better alternative yet!
