The first step in replacing any fuel tank is to remove all the old fuel. Seeing as I was planning on adding a dedicated fuel polishing system I used my new fuel polishing system pump. I made a home made stand out of some plywood and mounted the pump to it. I then connected some fuel hose a shut off valve, a 12v pigtail and a switch. I simply transferred the fuel in 5 gallon cans, through the Racor filter and I burned it in my homes oil boiler.
