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 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.

WOW!!
So I ended up purchasing this for my 1995 Honda Civic. D15Y8. (MiniMe) I do have an adjustable fuel pressure regulator installed and had my fuel pressure set to 32 PSI on old OReilly Import Direct pump. I still have not altered my fuel pressure and she’s sitting at 41 PSI. Automatically tells me I had to open my regulator up more to increase flow due to a weak pump. I can hear this new KEMSO pump when it primes and she sounds amazing. No more hard starts. No more stuttering and running lean. Took me 15 minutes to install start to finish. A+++

Smaller diameter than OEM, but worked with added zip ties.
Replaced OEM in tank fuel pump for 1986 Mazda RX7. Smaller diameter 1.5 " vs 2.0" required zip ties for easy installation. All parts were included for installation. While I haven't measured it yet, there appears to be more than enough fuel pressure and flow for engine to fire up immediately ( within 5 seconds) and to run smoothly, even under hard acceleration. Only time will tell about durability, ( the original lasted over 40 years, 196,000 miles).
