Testing the WUR high cold control pressure

Is there a way to test the WUR? Voltmeter?

I am trying to chase down a high control pressure issue and wondering if it's the WUR?

If I remove the line from the WUR [outlet] to the fd and turn on the pumps, pressure is still ~6 bar and there is no gas coming out of that line, shouldn't there be?

Thanks

You'll need to post a picture of what line you're removing. Can't imagine a situation where you wouldn't see fuel at the WUR if only one line was removed...???

Oh and a WUR can be tested for the heating element. ~23-28 ohms
