Howdy. Running an old b model in the 700 plus hp range and starving for fuel at full pull. Running the fass system with 2 filters but also left lift pump intact as well as the primer pump with its filter which i run a 1r1712 (10 micron). Im looking for a part number for a hydraulic filter to serve as a bird catcher in place of my primary. Need 1"-14 thread pitch. I have spent countless hours researching gph and its like pulling gnats teeth to find comprehensive filter specs. I think its due to most filters having crappy numbers that they prefer to not advertise the specs. Can anyone shed light on this?
