I finally remove the smog pump from the 86 Mustang. The tubes were completely clogged so I wasn't helping the environment. I was surprised at how easy it was to perform the task and surprised at how hard that pump pulley was to turn. My engine will now spin more freely and mpg and power should increase. Took about 3 hours total with camera moves and setup. Thanks again for watching. The car is running way quieter now.
