i havnt tried it yet but it looks preeety simple and easy to do, the only problem is i have backing on the tank where i want to drill, will this be a problem?
It is mate, as for your backing just drill that as well, just take your time, and just put your pipes through the holes. Get the right bulkheads and will be able to make the tank as long as you need.hth
