I've replaced the suction line, new filter, pumps were both exchanged with
known working ones, and valve body was also swapped with another.

HI Ok, this is still a suction line issue what I suggest is 5-10 gal container run a hose from the suction side in the container, and a return line in the bucket this will eliminate any issues with the tank and P/U line from the tank let me know
