Does an oil furnace that has a 2 line set up need to be bled?

Not usually. But is a problem does come up you can open the bleeder a bit to assure you have oil in the tank.

A properly installed 2-pipe fuel system does not have to be bleed, you should always prime the fuel pump on a new install to help the pump seal and pull the fuel oil...

(I can not find a bleeder valve on this burner)
Will the system circulate the air in the fuel line going to the furnace through to the return fuel line back to the tank. Thus bleeding itself?
If so do I need to use a jumper on the control box to keep the furnace running just like you would do to bleed a single line setup? Thanks for the info

How do you prime the fuel pump on a Beckett AF-15 oil burning furnace?

From years go by all I can tell you is there is a very small valve like item on the pump. I believe yiou can attach a 1/4 ID plastic tube to it and unscrew the valve with a wrench a bit to allow flow.Your two pipe should self bleed.

Are you sure you have OIL?? Are you sure the filter is tightened so as not to allow air in??

With the Beckett burner off, remove one of the top plug ports for your pressure gage on the oil pump, and pour in fuel oil until you fill up the pump gears... replace the plug, and start the Beckett burner. After it has ran a bit, open the bottom bleed valve and bleed a bit of fuel oil into a container ( after the burner has ignited )
