Fit my 2019 Honda Rubicon 500 perfectly
This was a simple plug and play rebuild of the fuel pump for my Honda Rubicon ATV - 2019. I just rebuilt the defective pump as a backup and installed on OEM complete pump in my Honda. If I had known how easy it was to rebuild the old pump I would not have used an OEM complete pump at a cost of about $160. Lesson learned. This kit is complete with everything you need and even has a new 'O' ring to properly seal the pump housing/fuel tank joint. It took about 30 minutes to disassemble the old pump and replace the old pump motor with the new. Take plenty of pictures of the complete pump housing before you start disassembling it.

Exactly as advertised
Installed pump and replaced tank. Killed battery pressurizing system! After battery recharge started immediately and has been working as expected for a week now.
