I received my 4 faucets, shanks, and accessories for my fridge conversion. Now, I'd appreciate some advice or ideas as to where to place the 4-way manifold in the fridge. The fridge's floor area is slightly over 4 square feet, and will hold 4 cornies fairly easily. The CO2 tank will be on the outside. Is it necessary to bolt/mount it on the inner fridge wall? Is there a simpler way? Thanks.
