steve s Posted September 27 Report Posted September 27 Moritz Guage question on vac pressure. Does anyone know where the line is to the gauge I am told these deteriorate over time. I looked behind the panel, but couldn't locate it to replace it.
skykrawler Posted September 27 Report Posted September 27 I might be useful to provide information regarding the model and year of your airplane.
Hank Posted September 27 Report Posted September 27 Mine comes from a T in the line above the oil filter and goes through the firewall. My gauge is at the top of the panel.
Fritz1 Posted September 27 Report Posted September 27 Think the vac line does not go to the Moritz but to a pressure transducer in the pilot footwell

My vac pressure reads 3 even before I start the engine and just stays at 3. someone on here suggested the line has probably deteriorated
kortopates Posted September 28 Report Posted September 28 Thanks I will take a look. My vac pressure reads 3 even before I start the engine and just stays at 3. someone on here suggested the line has probably deteriorated If the line had merely deteriorated, it would read zero not three. You’re showing gauge error, regardless of what else may be wrong.Sent from my iPhone using Tapatalk 1
N201MKTurbo Posted September 28 Report Posted September 28 I have an old Bendix Pioneer 2” vacuum gauge I bought on EBay for $10. It is my gold standard for checking vacuum. It is dead on accurate. I checked it against a mercury column at the instrument shop.

The transducer sits on top of the wheel well for anyone looking for it. There is a tee in the line behind the AI and the hose runs down to the transducer. Hope this helps someone else. It's a pain to get to and see what you are doing. Edited September 28 by steve s
