Here's how to test. Easy.

Start your engine and pull the primary filter while it's running.

Worst you'll have to do is bleed the system to get it started again.

If the engine shuts down right away, then it should in a runaway.

If it takes a little time, it still could shut down the amount of flow it takes to keep a runaway going.

If it takes a LOT of time to run down, then it's probably a given that it'll blow before the fuel runs out.
