I like remote reservoir power steering. It makes it so much easier to check or add fluid. Reservoir on the pump, does eliminate extra hoses, Though.
My Volvo S70 is remote. My 850 is on the pump, but the pump is so high it's easy to get to. My old Saturn had the reservoir on the pump, but it was also on top of the engine. My truck is the hardest one to get too. My Buick is similar to the truck, but I think it's easier to get to.
I wouldn't mind converting the truck and maybe the Buick to remote reservoirs someday.
I'm not a fan of sheetmetal screws, but what is wrong with the clamps? They keep hoses secure, and are padded.
