If you're using a truck cover you need the truck pump. I'm the one cutting up the truck covers. Because I use gm cs130 alternators with no a/c or p/s. You will also need a truck balancer if you have a car engine
Want 2 more covers and balancers? I've got no use for them. :D
What do you use to pull the truck balancers? The typical pullers work for a car balancer but the truck one is different. I found something last time but it was pretty redneck and I need to do another.
