Thomaspin you bring up a good point. If the filter is underneath the car what is the benefit? Short of an oil filter relocation kit there may be little.
I admire the inventiveness in creating the "suction" device. However, it appears that you are adding an extra step to the process. Why use an expensive compressor to create a "compressed air to venturi to vacuum device"? Why not use a simple shop vac with the water pipe/bong contraption? Feasible?
Just curious. Any details on construction are appreciated.
