Hyraulics on 3pt not working.. jumping/not lifting on ford 1900. Please Help

[dustyfontenot]

UPDATE: I replaced all the o rings on the banjo bolt on suction and discharge side( they were in bad shape) And I replace the gasket on the filter. I then replaced the super s hydraulic oil with travelled premium hydraulic fluid from tractor supply. And the hydraulics work awesome. It lifts like it suppose to and no more shaking...It was either the fluid or it was sucking in air from somewhere.. Who knows. But the good news is that it痴 working again!!
