    Sure. It's easy to do. Just do it, Just be sure that the oil supply is at least 1/2" OD tube, 5/8" (1/2" CTS) is better, because if there is any restriction between the burner pumps and the oil tank/filters, one pump will suck off the other, and the "Other" will loose prime.

    And you know what happens when THAT happens. The phone rings because the red light is on.

    Check Valves don't seem to help.

    If the burners are above the fuel level In the tank this would be problematic. I wouldn't do it.
    Burners below the fuel level in the tank shouldn't be a problem.

    If you really had to you could install a relay that only lets one burner run at a time. A preferential relay where the water heater has preference. Just a band aid to a problem usually.

    Two Tigerloops. And a properly sized suction line if the tank is below the burner.

    You can do it. I believe in you but, it might not work after you do it. We are kinda missing a lot of information.
