When hooking up my autometer boost/vac gauge to a red vaccum line, does it have to be the same vaccum line I'm tapping to for my bypass valve? There are many red vaccum lines under the hood, will they all serve the same purpose?
You can either place the sender in the hole in the DS of the block between cylinders 3 & 4 or like I did and drill & tap the thermostat for the sending unit.
