Ellie ★★★★★

My NA's original pump finally gave up after 28 years, and this 420lph unit dropped right in with the included install kit. The car fired up immediately and the fuel pressure is rock solid now.

Nicholas ★★★★★

I swapped out my old pump for this DW420 and the install kit made it a straightforward job—everything fit perfectly in the tank. The car fired right up and now pulls hard all the way to redline.

Emma M. ★★★★★

The 420lph flow rating is plenty for my turbo build, and the included install kit meant I didn't have to hunt down extra parts. It fired right up with no priming issues.
