2nd placement of can

Original placement was where R/X shows in their installation videos (attached to the master cylinder). I felt a small vibration in the accelerator pedal mounted there, like a cell phone was vibrating all the time. Tightened the bolts and the vibration went away, but came back a week later. Not a good point to mount the can. This is the 2nd location I mounted but it's not very good either as it's difficult to get to the valve to open and hard to find a container short enough to fit above the battery box and below the can.
