Air grabber stopped working

[MikeyT]

Hi Guys,

Up until tonight my Air grabber was working awesome on my 1972 road runner, then poof.... stopped. I am trying to figure out where to start.

Does anyone have a diagram of the under hood set up they could load or send me as adobe file?

Also any particular area's where I should look for for trouble shooting would be great.

thanks all

Start by checking that all hoses are still holding vacuum. Put a known vacuum source on the air scoop piston to see if it will actuate. Ensure the vacuum canister hasn't developed a leak. I'm betting there's a crack in a line somewhere, especially if it's original tubing.
