Newby here, ASE auto, not chainsaw mechanic. The only thing I would personally do with the China tanks would be upgrading the pump, they're dribbler's compared to real solvent tanks. Little Giant sells a solvent specific submersible pump that should really upgrade the flow, but it might be a bit much for a small tank. There is a problem with bacteria build up and other nasties when using water based cleaners. There are filter bags that companies like Safety-Kleen use to recycle the solvent, takes most of the crud out. Don't know if they would sell to someone outside their customer base though. I'm probably going to rig one out of pvc and paper towel rolls. Might be slow, but should take out all the small micron abrasives that ruin four and two stroke stuff. Have fun, I'm spoiled, mine is a 40gal. tank, I need flow for all that grunge on the cars everyone drives.:newbie:
