I hate to be blunt, but if you can’t figure out this on your own, you shouldn’t even be attempted such an oil burner conversion. Several connections have to go to the new burner including connections for the primary burner control, thermostat, stack safety switch or equivalent, etc. Also with the shorter burner tube, the flame may not be properly positioned in your firebox. My final worry is that a modern flame retention burner such as a Becket AF series, burns hotter than older non-flame retention burners. I’ve seen them burn right through the firebox material in older furnaces or boilers. Did your furnace have a flame retention burner to begin with? Doug

Pretty sure wiring is right and I know now I have to get a longer burn tube.Problem now seems to be pump blowing motor breaker if oil supply line is hooked up to input on pump.The old input for this burner seems to have been screwed into bypass connection which I can get no pressure from.Would a clogged spray vave cause this .I have cleaned it an pump with had some gunk in it ,but problem pesists.

If the pump had been used on a 2-pipe system, it will still have an internal plug in place.  This plug must be removed for your 1-pipe system. (this may or may not be related to the motor overloading.) The exact configuration depends on pump mfr and model. Do a web search for the model and maybe come up with info. Jim
