Here's a couple of pictures to help illustrate what's going on with the module.
First, we have the DSV installed in the module in place of the factory pump. This does NOT require breaking of the module or parts just in case the owner would ever want to swap back. Please note, the green line was used for photo contrast and would not be used with the shipped product. The hose we ship is clear and is bio and veg oil compatible. The green line is not. Also, we now go to the top of the module bypassing the bar in the center. New photos will be more clear.
The second images is with an old prototype module that we used to mockup the DSV Hiflow kit. As you can see, everything mounts in the module. The DSV in the base is the same design as the first picture. However, it is 1/2" internally.
