Bentone Burner - Oil Pump Replacement

I wished to replace the Oil Pump in my Bentone Sterling ST108 Burner. I studied a video produced by Danfoss outlining the steps to be taken in replacing their BFP 21 L3 Oil Pump.
No problems except the video featured a different burner.

I'm going insane in trying to figure how I can detach the pump from the burner bodywork of the Bentone burner.

Can anyone please help?

Many thanks,

Jimmy

Under the pump theres two grub screws undo them and the delivery tube plus pull out the coil plug
and it will pull off there is a coupling make sure it's in properly and in line when re fitting pump.Bob

Many thanks Bob - Up and running - I am very grateful to you. Jimmy
