I have a vacuum leak from a t connection under dash, it connects from pitot, airspeed, not sure of third hose, would anyone know the name and where I can buy it?

This is typically a mechanic’s area of expertise...

Buying the parts is one thing, but making sure they are leak free and working properly.... is important.

Check In with your mechanic for such important details...

pitot isn’t typically connected to vacuum... so you don’t have a vacuum leak...   

Just trying to be helpful...

I had the same issue, there is actually three t connectors, might as well change all three, I ordered t's from aircraft spruce twice, they sent the wrong thing both times,  I ended up going to a local avionics shop and getting some from them, they are 1/4 inch.   don't buy them from home depot, it doesn't work.  also, I found if you remove the panel under the driver windshield, you can see all three and actually work easily.

How about Don’t buy them from Home Depot because it is a certified airframe and if you are installing them in your aircraft you are not only breaking the law, but are also putting yourself and others at risk.
