Question Convert from underground oil tank to above

Hello All,
I have a 500 gal oil tank that is underground and need to buy a oil tank to go in the basement. So I have two questions.
The first is to do with the oil pump that is on the burner. The one I have now pumps the oil from the tank to the burner and back to the oil tank.
Correct me if I am wrong but the new aboveground oil tank has only a supply line with no return line. Is that true? If so do I need a different oil pump for my burner?

The second question is to do with the oil fill pipe to the new tank from outside.
Oil fill pipe to the oil tank and a vent from the oil tank to the outside, right?
Thanks in advance

Bsmt tank

If you intend to feed the burner off of the bottom of the new tank, the pump would have to be converted to a one pipe configuration. If you can give me make & model of the pump, I can probably tell you how to do it.
As to your tank piping: Yes you need a fill pipe (2") & a vent (1.25" minimum) with a whistle (ventalarm).
These comments are code acceptable in my area but I suggest you check with code officials where you live.

Grady is right. The most common fitting for the vent is a combination ventalarm and gauge. It is important for the company who fills the tank to be able to hear the whistle from the vent alarm to know when the tank is full. Make sure you have at least 5 feet from the tank to the appliance and at least 3 feet from the tank to your main circuit panel in the house (fire code). Also you must use black steel pipe for the fill and vent. You can have pieces cut and threaded to your specs at HD and others. Use a thread sealant that is compatible with oil but NOT teflon tape. Post back with any other questions.
