Manual or power rack for 3G hemi

I'm running a power rack but I'm having some issues like whine from the pump and jerky steering response. Not sure if it is the rack or pump yet. Manual would have been a lot simpler and far less costly. There is a fair bit of plumbing involved with the power rack with lines between the pump. rack and reservoir. Only thing I don't know is the steering effort with manual - but someone must have done it.
