Wastegate Y Hoses

[10 SEC BUICK]

Wanted to replace the wastegate Y hoses. Does anybody know the vacume hose size I need to replace those worn out hoses with. Thanks in advance, Jon.

I just replaced mine and I used the 1/4 inch fuel line hose. The vacuum lines in that size were a little thinner so I went with the thicker ones in the fuel line. They were a little tougher to get on the "Y" but I know they aren't coming off.

7/32 or you can go with the above choice both will work

5/32" vacuum line to the wastegate solenoid and 7/32" size to the compressor and to the wastegate.
