Review: Great product - This carb rebuild kit has been on my bike (2006 Harley Sportster 1200) for about 200 miles, everything appears to be working perfectly. I’ve never rebuilt this carb but I watched some YouTube videos and installation was easy. Lastly you can’t beat the price.
Review: Super Fast delivery and simple to install - So, this arrived super fast. Like, 2 days. I wasn't even prepared to install it yet, but I was able to tackle it the day after it arrived. The pump feels like its great quality and the install was simple. The only thing I did not like was the supplied plastic fuel line. I'm sure it would have worked, but I went to the parts store and bought my own. After installing, it primed very easily and the car crunk right up. Its not loud at all either. In my 240sx, the pump is located behind the rear seat in the trunk area and I could not hear it in the cab once I put the cover back on and closed my seat.

### ⭐ Great until it wasnt
*by D***G on September 12, 2025*

Looked great, great packaging. Install went fine. After roughly 2 hours of runtime the pump has shorted internally and stopped working. Reached out to support and nothing back.
