Thanks for sharing your setup. I had a couple questions about it too. I'm new to vacuum setups and haven't actually seen one in person. If I understand right the main line feeds directly into the pump and the pump dumps into whatever you have for a sap tank with this setup right? (No releaser needed) Also, what type of 12v battery are you using? Do I need a deep cycle trolling motor type battery or would one of the cheaper lawn tractor type batteries have enough amps to run it? I already have the charger so this looks like an affordable way to get into vacuum. Thanks.
