Do not buy
Waste of time, waste of money. Pump stopped working on 3rd day after install. Tank was drained of old fuel and fresh fuel added before installing new pump.

Works great, but had to slightly modify my RX300 bottom plate.
First and foremost, assemble your whole unit gently if this is going into an in tank fuel level sender and pressure regulator all wrapped into one unit like I found myself doing in a 2000 Lexus rx300. There are some small tabs in the bottom of this pump that protruded farther than the thickness of the rubber cushion so I initially tried cramming it together and actually broke my new fuel filter. So to alleviate that I replaced the fuel filter and used a soldering iron to melt slots in my bottom cap to accommodate the pump and have it still held quite snugly, but not so tight as to break another new fuel filter. Works amazingly now. Being a 25% higher flow than my stock pump, I expected it to be slightly louder when running, and it is. Not excessively loud by any means. Similar to the sound of the stock fuel pump in my 2005 Jetta. Just a couple items I thought someone may appreciate knowing ahead of time, but it truly is exactly what I wanted despite my issues with my application and for functionality and performance I still gladly give it 5 stars.

The electrical connector on the pump is not compatible with the OEM connector on my 2000 Lexus GS400. The physical pump is the same form as the OEM Denso pump but the connector is different. A connector is supplied along with a couple of crimp connectors to splice the connector onto the fuel pump circuit but it requires cutting the factory harness. Not hard, but not ideal. Also the kit does not include the O rings which should be replaced with a fuel pump replacement. The pump itself appears well constructed but only time will tell.
