It's an MPL 503 pressure switch https://www.aircraftspruce.com/catalog/inpages/mpl500series-ps.php The V-vacuum side connects to the port in the leading edge and the pressure side to the static system It tests correctly on the ground with slight suction on the port Read this topic online here: http://forums.matronics.com/viewtopic.php?p=493865#493865 ________________________________ Message 2 _____________________________________ Time: 03:50:32 AM PST US Subject: Allegro-List: Fuel tank internal coating degrading From: "aerosiam" While doing the annual on a 13 year old aircraft, I used a 1 inch tube to siphon out the fuel. I assume the large black rubbery deposit in the photo is part of the internal coating of the tank. Has anyone else had this problem ? My concern is that the coating is degrading and the fuel will damage the fiberglass and also that the piece is large enough to wrap itself round the finger strainer in the tank.
