On my 1994 achieva its vacume controlled i had to replace the line going to the controller. It was broken. It runs frin the top of your intake throttle body its a small line maybe 1/8 inch down to a vacume tank in lower front drivers side, from there it runs up the drivers side fender accrossed the firewall towards the top and into the passanger side through the firewall. It comes though behind the glove box and over to a vacume spliter behind the vent selecter. mine broke right at the vacume spliter. Word of advise use heavy stiff plastic vacume line to replace it anything less will colapse when vacume is applied. this solved my problem. the line is very easy to replace.

How do you create an electric fence?

You need an electric fence controller, first off. The purpose of an electric fence is to scare whatever touches it into staying away. If you try to make one by wiring it to mains power, you will just kill whatever touches it. You can get a controller at Tractor Supply Co. After procuring a controller, running an electric fence is a simple matter of stringing wire on insulated posts. You connect the controller to your fence and ground, and there you have it. Talk to the salesperson at the Tractor Supply store. They will have controllers, wire, insulators, posts that can be easily installed, gate handles, and whatever else you need.
