Re: Picture request - factory vac gauge connections to the back of the dash
The OEM hard line does not connect to the engine. It ties into the power brakes on the larger trucks close to the firewall, and really has nowhere to make a direct connection on our trucks. I added a rubber hose to the end and ran it to a vacuum tee pretty much the same as Coley has pictured.
