I have a used filtration system from golden fuel systems. It comes in a hard case and can attach to a car battery to pump and filter the used oil into storage containers. It needs a new switch and filter but it works fine otherwise. It sells for $1200 new, but I would sell it for significantly less, make me an offer. I sold my '98 Benz with a dual tank system and this has been just sitting around so i'm looking to get rid of it.

Let me know if you're interested. The unit is in Cleveland, Ohio but I can ship it as well.
