So with something like the hydromat, you don't need to get carried away with baffling or sumps etc? You can do just a wide open tank? I'm getting some schooling on GTAW [tig] welding and I have most of the equipment needed to make one. I'm going to mini tub my car which will run the springs against the existing tank so the plan is to make one narrower and deeper. It will have the pump mounted inside. If the hydromat is the ticket instead of the Stealth pump, Vaporworx etc I'll go that direction.
