..Great picture. Wish more would show their ideas in picture. Looks good.
I asked about the DEF-Loc sitting in a urea environment with potential contact by ammonia and was told that the aluminum alloy used for these is not particularly reactive either to DEF/urea solution or ammonia, plus the anodized surface makes it so that no bare aluminum is actually in contact with the urea solution or ammonia.Besides, ammonia will corrode aluminum. Best stick with plastic.
