Don't loop the lines, will be really heavy as you still have to force all he fluid around. If you don't want to swap the cross-member and rack to a manual one you need to tear the rack down and remove all the valves and seals, then just grease the internals and plug the holes for the lines with bolts.

Shorter steering arms with the P/S isn't that twitchy though, basically the same as manual steering with a quaife quick rack.
