I looked at these photos yesterday and didnt have time to post.
The only thing that worries me or i would be concerned with is the cheap fittings you have used on the tank its self.
MY personal opinion would have been to buy a cheap elbow at say £4 with a 1/2inch barb on it.
With what you have on your tank, i can honestly see it disconnecting and leaking in that corner.
I know you have done stuff on the cheap as I have been reading your posts with great interest but for me something you dont cut corners on.
Sorry to poo poo on your parade
