So I have replaced my pump twice within 4 years and maybe 300 hours of use. When I talked to the CAT dealer they told me those pumps last about "2 years". Which I think is pretty awful. I just replaced my pump with a Facet pump. These appear to be the same pump that Cat rebrands, but it is only $70 vs Cats $260.
The Facet 40185 Cube 12 Volt Fuel Pump delivers maximum flow of 32 GPH or 9-11.5 psi max pressure. 1/8 NPT female ports. 96 inch dry lift rating.

(They have a few different options to choose from including one that looks like the exact cat pump replacement)
I picked that one because it is close to the Cat Requirement of 12psi at 30GPH.
I am now wondering if maybe I should have got this one:
This Facet Cube Style 12 Volt Fuel Pump has a much larger than normal 96 inch dry lift capability. Maximum fuel delivery is 50 gallons per hour and maximum pressure is 12 to 15 psi.

But I just installed it, so it might be too early to tell.
I also chose to move away from the CAT inline screen and have moved to the Napa 3972 filter. The reason for this is that my fuel contamination had larger chunks in it the would get trapped at the super small opening between the bottom of the screen and the intake tube. The Napa filter has a bit more space and I am optimistic this will help with my particular problem.
