Just joined and am trying to find info on routing the vacuum lines on a Cobra upper manifold. Have found some pictures but still do not have enough information to complete the transfer of my cars old vacuum system to the one for the Cobra manifold. I have an 88 GT convertible which I am restoring from top to bottom......thanks for the help.

Here’s how it’s plumbed from factory

However, with a speed density car, there is no port for the MAP sensor. It needs its own dedicated port off the manifold for most accurate readIng

The coolant lines get capped. For the rear intake fitting, remove it and install a 3/8npt plug.

For the front line, I’ve seen people insert a bolt into the line with a hose clamp and tuck it. If you have the skills, cutting and welding over the fitting on the coolant tube is Also an option
