I feel bad saying things like this once work has already been done but... I would not use those barbed bulkheads that deep blue provides, they are complete junk. Im on my second DB tank and have tossed them on both builds. Id get some ABS slip x slip bulkheads from BRS and hard plump all the way. They are only a couple of bucks an from the looks of your plumbing, looks like a pretty quick repair
