Austintatious Posted February 18, 2025 Report Posted February 18, 2025 If you are running a surefly mag you need to be sure that the pressure sensing tube is curved to point rearward or has some filter or blocking apparatus to prevent rain/moisture from entering the tube. My partner was flying our Rocket for an extended period in the rain. Moisture got into the tube and caused an e-mag failure and a precautionary landing. Had to get a replacement shipped out and installed to continue the trip.
N201MKTurbo Posted February 18, 2025 Report Posted February 18, 2025 Is it actually using the pressure sense line on the Rocket? If it is, it should be connected to upper deck pressure. If it isn’t, it should be plugged.
Marc_B Posted February 18, 2025 Report Posted February 18, 2025 When I spoke with Surefly when I installed mine, they recommend about a 3 inch piece of tubing connected to the pressure sense barb and directed down as a drain. They did not recommend capping the pressure sense barb. On NA application the barb would be connected to the manifold pressure. For a Turbo application they aren't approved for variable timing so you'd wouldn't connect to MP, but rather just functions as a drain. 2
