Reply To: Fx- 3 vs 4 Stage on 480cc
Get the 4-stage. I used the 4-stage for my FX Impact with the same 480cc bottle. As the pressure gets close to 220+ bar by “switching” the pump from 3 to 4 stage makes it easier to pump but takes more strokes. It’s about $20 more for the 4-stage pump and someday you will thank yourself for that extra feature.
