tiger loop

I am having trouble with my church furnace, so any of you guys that work for their church know this means I had better get it fixed pronto.
I have two oil burners connected to a two line system. 20 years ago when we installed it, I could not run both systems on the two lines as they would run out of oil and one or both would lock out. I put the smaller unit on a single pipe while keeping the larger unit on the two pipe system. (I just did not hook up the return line to the small unit)
Now this winter my small unit keeps losing its prime. I would like some advice on what to do next. I have never used the tiger loop but have been doing some reading on it. Is that a solution or do you guys have another?
And for more information, the tank and the lines are under a concrete walkway so I cannot access them. And the church hall is also on the same lines, there are two units in the hall, they both have no problem.
Thanks

Personally I dont like Tiger loops but, a lot of people do so I not putting them down.

any burner that has to lift oil from a tank needs it's own suction line in my opinion. It can share a common return with other burners . Everything needs to be sized and piped correctly.

The fact that the small burner used to work on one pipe and wont now means you have a suction leak and a tiger loop on that is a band aid as far as Im concerned. It could be caused by something else but a suction leak is likely.

You might..

try to contact Mr. George Lanthier, (firedragon.com)(?).
Years ago, he proposed a piping method that would accomdate two appliances drawing fuel froma single tank by way of piping configuration.

I have a copy somewhere, if I can find it.

Usually pipe independent or if a oil-powered water heater is involved, a "priority relay" may help. With two furnaces that is probably not a viable option.

Have used tiger-loop for outdoor exposed tanks with good results.
