Default vacuum tank
I have a 70 vette and have been tracing the vacuum lines to check for a possible leak.The diagrams for the operation of this tank show two ports. My tank has 3 ports.Can someone please tell me what hoses go to the tank? Thanks, Rob

Rob, Off the top of my head....

1 - Input vacuum source from check valve

2 - Connect to "T" which splits between 1 H/L relay and wiper door relay

3 - Connects to the other H/L relay

Check out Willcox's site for a real vacuum diagram you can use.

Yup, you need a better vacum hose diagram as the 70 tank has three hoses.

Thanks for the replies. After checking and double checking all vacuum hoses, turns out that I had a hose pinched by the steering column when I lowered it to check under the dash. Headlights would not go down, but ok now. Thanks again for all the help, Rob
