Sure, the water pump is 8" long, approximate 4" tall (including rubber mount pieces), and 4" wide at the mounting bracket. The tank measures 6.5" x 4" x 5". That kind of volume lasts about a week in my friends 500whp Mustang. He's got no space under his hood, so he stuck both his pump and tank in the trunk. They're stashed behind his interior trim panels with Dynamat applied to muffle sound. It's a really slick set up. The kit in my Scirocco is installed on the floor behind the passenger's seat. However, most folks just keep everything under the hood.
