Well I did all me upgrades-mc2100,hei dist,amd nutter.Now during my removal of the polution stuff i must have removed the vacum line to the 4wd avuator on the axle.I traced the the lines,one goes to the switch on the fender,i think this is for the 4wd lite. the other 2 stop and have a ck valve on them.I know one goes to a vacume sorce but I dont know were to get it.under the batt is a ball i think its a vacume tank,2 hoses are going to it but not conected.
1-were should i get the vacume from i only have two ports on my carb one to the dist advance,the other to the pcv valve.
2-need constant vacume
3-of the 2 lines which one gets hooked up I have the diagram in the manual but dosnt show were all of it goes.....
