After you pumped the tank empty. Pressure wash with a solvent to clean the tank and then strip the residue into 55 gl drums and have an eviomental company cart it away.
Here in the southland, I had to have it done to a vessel I was working aboard. Pumped off 12,000 gl to a tank truck. Pressured washed the tanks then filtered the fuel as we brought it back aboard. The reason why? We went through a case of Racor filters in about 9 days, and as we was going back off shore the engines started losing power. Turned the boat around and refused to take it out until they clean the fuel tanks. After that was done, we changed racors about every two months or so.
Lesson? Pays to clean your tanks, especially if they had set for awhile.
You should have seen the crap we got out of the those fuel tanks and fuel lines. Don't forget to clean the fuel lines also.
