Unless you have an aftermarket turbo you don't have a blow-off valve. What you do have is a wastegate, which isn't the same thing but somewhat similar. And as Joe said, you don't have a vacuum line either, it's a pressure line. Simple to hook up- look at the inlet of your turbo. Just behind that almost against the firewall you'll see a gold canister bolted to the turbo- that's the wastegate. It should have a nipple on it pointing toward the driver's side of the truck.. rub the nipp (oops wrong forum!) I mean hook the red line up to this nipple.

The vac pump is needed because the engine won't make vacuum like a gasser will.

Your very right, they have a vacumn PUMP, they do not make vacumn like a gas rig does. Thats why the OBS had a vac pump for the brake booster as well.

A normal blow off valve is not needed on a diesel.
