The bracket piece that is welded on the tanks was too far left causing the reservior to sit against the fuse box when installing. I had to sit it at an angle to line up the bolt holes. Also, I had to remove the o ring on the cap for the windshield fluid side because the pump can't spray fluid if the cap is sealed tight. My oem windshield reservior cracked so I'm just using this for the windshield fluid side so I can't comment on the radiator tank side.
It's over all it is a good product the only thing is needed is small holes in the caps to release the vacuum caused by either the sprayer pump or the heat from the coolant
Really awesome product, fits direct on my STI 2005, the only thing I would recommend is to change the hosing to more a colorful hose black, blue or red, the transparant one is way too ugly for the engine
