You video was basically well made. The only critique I would make is, toward the end of the video when you were talking about the fuel enrichment/charging pressure (engine under acceleration - low to no vacuum test) you were not clear in describing the vacuum pump's role and what you were checking for. Basically, the Vacuum Pump simulates what happens when the throttle is opened up and the engine suddenly goes to low Manifold vacuum and for that reason the fuel enrichment has to go up (lower fuel pressure) because the engine needs a richer mixture. This is important because if that 'charging pressure' is out of range one will get a stumble on acceleration.

… yes and showing the graph in the bench manual and how to read it was a good gesture as well, I have seen some manuals with the graph but the line axis was not numbered like yours is depicting line 1 & 2 ... also are you not suppose to stop watch/ clock time how long it takes to do the Control Pressure test, that is with the WUR plugged in to see how long the internals take to heat the spring inside and thereby increase the psi/bar on the gauge … ?

Hello ,one question ,what happen’s if you drive your car with the WUR electrical connector off (disconected)?will the engine run too rich in fuel ? Too much fuel ? Saludos

Yes - until the heat from the cylinder head heats the wur doing the job of the heating element

Thanks. Very informative. Do you have any suggestion about the checking the regulator if the pressure does not drop when pressurise with hand pump?

I'm sorry I haven't ever cracked a Warm-Up Regulator open to see the insides. I would reach out to Brian at www.rarelyl8.com/home.html

If the pressure does not drop, you have a bad diaphragm in the WUR. If you DO get a drop but it's not within the correct specs. AND you have made sure that your diaphragm is not leaking, you can adjust the pressure by tapping in on the plug at the bottom of the WUR (similar as tapping on that small shaft on the top of the WUR when you are setting the Cold Control Pressure).
