The bottle in this one, i dont think is original.
The last guy put this giant in there (its about 1 gallon and basicly square)
He mounted it where the battery tray is, since my battery is in the rear.
I am interested on what you were planning to make.
Stainless? 3x8?x15? PVC pipe? Capped or just plugged with drain and fill fittings? Recirculated or just drained?
I was into the HHO scene for a while.
They generate higher temps with thier liquid, and use PVC and Poly/Lexan tubes for different things.
I was thinking of puting together a new over flow out of 4in PVC, but didnt get that far yet.
