Garmin Service Bulletin 2069 - Kavlico Pressure Sensor Inspection

[TShort]

Thanks Justin.

Do you have a link to purchase the new 75PSI sensor?

Does it use the same connector / wiring as the current equipment?

Do you recommend any change to the oil pressure sensor as well, or just the fuel system?

Hi Thomas,

They do use the same wiring as the currently fielded sensors. You can purchase them through a Garmin Dealer using part number 011-04202-30 for the oil pressure sensor and part number 011-04202-20 for the fuel pressure sensor.

Thanks,

Justin

My fuel pressure rose to a max of 49.1psi within 5 minutes after shutdown. Lycoming IO-360.

I have the legacy sensors for oil & fuel pressure on my engine. Was concerned at first but no leaks since they were installed so I?m leaving them on for now. Advanced Flight Systems will have the new ones in stock in a week or so. I contacted Sansata Technologies in San Diego, the parent company. The new sensor should connect with the snap connectors on top to existing wiring harnesses.

From Sensata:

? This are using a Packard Metripack 150 connection, you should not have any issues connecting the new sensors with the existing harness.?

Checked mine today (IO360 Avatar servo), immediately after shutdown fuel pressure went to 45psi. Pushed the mixture back in and it immediately dropped to near zero and stayed there. My new procedure AFTER shutdown will be to go full rich mixture, then ICO. Seems to solve the pressure spike issue. Only thing I can figure is that this is due to the Avstar servos NOT incorporating a fuel return line. Anybody see this fuel pressure spike with return line systems?

AFP system with purge valve, pull the purge valve, engine stops, pressure goes to '0' with no engine flooding.

Justin,

Can we use the alternative part numbers being referenced by AFS/Dynon with the G3X systems? Seems the new part numbers they are referencing have much higher burst pressure specs. Will the G3X sensor characterizations handle those as well as the TSO'd part numbers you reference above?

Mine are not leaking but if there is extra insurance to be had, I would swap em out as long as I knew the alternative is truly better from a temperature and burst pressure standpoint.

I talked to Garmin and they are recommending the 75psig sensor (which is apparently TSO'd). Part number they gave me was 011-04202-20.

They said they could not comment on any of the other manufacturers recommendations but that the G3X was pretty lenient on what sensors could be used...

I was not able to find any of the P255-150g-e4a sensors that AFS recommends; I called them to see if they had any and they asked me what EFIS I was using. I told them Garmin and they said they only had a few and would not sell me one because my system is Garmin...saving them for the AFS customers.

I was able to find the Garmin 011-04202-20, though. Be careful, I kept getting contradictory info...for example, if you put that part number in the ACS website, it will give you the 50psig sensor, NOT the 75psig.

There are also the sensors such as the UMA version...

Anyone have the actual Kavlico part number. If found this https://store.schnitzracing.com/kavl...iABEgJdTfD_BwE

Go back and look at post 7 in this thread. That document has Kavlico part numbers. And your link is the old style that's being retired.
