Another vacuum thread...304 engine
grunt
Active Jeeper
Trying to figure out my vacuum lines. I have the original motorcraft 2100 on my 1979 AMC 304 engine. It has the EGR, aftermarket air cleaner. It does not have the evap system or canister. Looks like the 3 port CTO is in the wrong spot? Also where do the two prongs off the thermostat housing go?....
