Does a stock diesel vehicle get any benefit from a FASS system? No.
If you're racing, there is certainly a benefit to lift pump.
I run the PPE pumps for competition. I've made 798 rwhp uncorrected with a single turbo, stock injectors, pure #2. With twin turbos, 936rwhp in Bonneville trim.
The whole 'air separation' thing is comedy.
