Hey mate, this was probably one of the biggest I <3 Bananas arounds to date with my car. I melted my cradle 4 times trying to figure it out. I eventually gave up got a new cradle and ran power and earth straight into the standard plug I get good volts at the pump and have since had zero issues. Regarding the issue for the bulk heads though, I did find that it was always coming lose and drawing more, you need to make sure you are drilling the perfect size hole to let the inner seal from the bulkhead drop in and seal. At times it was not lose from the top, but once I pulled the cradle I noticed it had come lose from the bottom. If I could go back I would have done what I done now but after the first cradle.
