thanks for the interest in a 9 year old video!! at 1:11 that "big hole" you see is not in the brake booster, it is in the gauge itself. it accepts a light bulb to illuminate the gauge. it has absolutely nothing to do with how the gauge performs. and to address a 7 year old comment below that i did not see until now, no - the gauge does not need electrical power to work. you see the other good gauge in the video right? no power needed to either gauge - they are vacuum gauges. both hooked up in exactly the same manner - one works, one does not. end of story.
@@linckeil yes i know is a old video my point is that why the gauge is not working because it have a hole in that hose not the gauge the hose check it again...
@@leroyestrada1616 i assume you are referring to the black mark on the hose about 2 inches from the gauge? right next to the number 9 stamped on the hose? that's a spec of paint - not a hole..... in fact that same hose is still on the vehicle today and operating the brake booster. if it was a hole, i would have no power brakes and a substantial vacuum leak causing all sorts of engine problems.... i think i still have the faulty vacuum gauge somewhere. If you like, I would be happy to dig it up and send it to your door for $20. you can run your own tests with own hose and see if you have any different results.
@CHS191 did you watch the video? did you listen to the commentary? both gauges are "T'ed" into the same source on the intake manifold - as you can clearly see in the video and as I clearly state in the commentary. I put this video together so that the guy who sold me the gauge could see it was not functioning. if you don't believe me when i say the gauge doesn't work, you are welcome to come check it out yourself.
