93 vacuum lines
 

I need a little help finding my vacuum lines im tryin to install my boost guage but dont know where to tap in? Any ideas

A 93 does not have vacuum lines.

The boost gauge should be installed on the pressure side of the turbo-there is no factory access for boost gauge installation.

You must make your own provision to install a boost gauge.

Most folks drill and tap the upper intake to accept a pipe threaded nipple for the boost gauge line to connect to.

Leroy Diesel makes a boost bolt though that can be used in place of one of the center upper intake bolts to make plumbing the gauge line easier.

Great thanks I was guna say I'm not that dumb to not be able to find em if there there. I appriahiate the help
