Maybe yes, maybe no.

If you are hoping to make it pick up more than Ford designed it to the answer is no. The designed lift capacity is determined by the diameter of the lift piston, the hydraulic pump pressure, and the geometry of the lift linkage. The hydraulic pressure is limited to 1600 PSI by the internal OEM safety relief valve so even if you add a second pump that produces a higher pressure the lift cylinder will never see it.

On the other hand if your lift is weak and you are getting less than the designed lift capacity because your internal pump is worn and isn't producing 1600 PSI pressure an external pump will make up the difference. In that case an external pump is a good way to restore the lift back to it's designed lift capacity.
