    You would need 2

    one for each unit,they work well. How about a preference relay?

    Tiger loop

    the tiger loop is the answer to your problem. Depending on the firing rate of the two oil burners, it will determine if you need one or two. I have been successful in running two burners off of a single unit, each was firing 1.35 gph. Just tee your suction and return line from the fuel pumps, and away ya go!

    tiger loop

    I have used one tiger loop to run two units to resolve this kind of problem. Put a tee on the suction side and two check valves(one for each burner); the return just needs a tee. Really the important thing is to know what your vacuum is! Are you dealing with high load or an air leak? If you're sucking air the tiger loop might still work but I would fix the air leak instead. Unless your tank is under a slab or something, that is.
