Hello all, I've been searching old threads and trying to find my answer that way, but not finding exactly what I need.
I just acquired my '81 AMC CJ7 yesterday. It has sat for 4 or 5 months, and 6 months prior to being moved then. I want to freshen it up a bit.
My main question is regarding the vacuum lines. I have a line coming off of the carb, with a few inches of line, then a tee fitting. I'm not sure where that line goes. I'm going to replace the fuel filter and verify that the return lino the tank is clear.
What do these rigs need vacuum provided to? I figured that I could buy a few rubber vacuum caps, bypass mostly anything that has a vacuum hose hooked to it, and run a vacuum line from the carb, to a PCV valve in the valve cover.
Anyway. Im happy that I found this forum! Now, Im off to NAPA to buy a fuel filter, 25-ish feet if fuel line, two engine mounts, a transmission mount, an oil filter and some oil. Gonna get this rig freshened up, and start driving it.
