    Default Oil pressure line

    I am reinstalling my old Oil pressure/temp gauge in my PA-20 and have the copper line that came out when I started the project, cleaned it up looks good, so I am reusing it. I am not able to find a part number for the fitting or hose on the engine side of the Oil press/temp gauge, I now have a O-320-A2B engine.
    Anyone know where to find that information or what the application is ?

    Read the printing on the hose so that later down the road when the house starts to crack you can obtain just the hose from Aircraft Spruce. Beats buying the whole assembly everytime the rubber starts cracking.

    Or make one with good Parker hose with AN fittings. Use a pop rivet with pin drilled out for a restrictor.
    That will last longer than the hose Spruce uses.

    The hose Univair uses is Aeroquip 306-4.
