    Oil Line Vent & Temp Sensor Locations

    We are rebuilding a 1994 Polaris SL 750 jet ski that was already partially disassembled when we bought it. We are trying to figure out where the vent for the oil tank connects. We also have a second temperature sensor hanging from the electric box that we can not seem to find a place to install. An identical sensor is already installed in the fuel rail, but we can't seem to figure out where the second sensor should go. I keep searching through the parts and service manuals and your wonderful forums, tips & discussions - by the way - thank you!! Your information is wonderful!! Any help for these quandries?

    This is where the sensor goes. It's on the exhaust pipe down low.

    Welcome to Green Hulk!

    SD2K is right about the extra sensor. Right were the exhaust pipe ends and the rubber hose connects to attach to the waterbox. Odd threaded webbing to put the sensor.

    As for the oil tank vent... it goes nowhere. I has a check valve to allow air IN and a small hose. For the '94 SL750, service manual shows this check-valve line being held in a holder on the side of the fuel/water separator.

    It just needs to be zip tied to something to keep it up out of the way.......
