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.

Solid for the price and installation isn't too hard.
Works as it should. It is a bit longer than the OEM so it'll take a bit more elbow grease to get it to sit as it should. But it good so far. Installed on a 2007 sonata 3.3L V6.

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.

تعمل بشكل جيد لكن صوت المضخة عالي ولم ارى فرق بالعزم او صرفية وقود أقل .. ما انصحكم تشتروها
C**.
Despite saying so in the description, this does not fit a 2009 Hyundai accent as the nozzle on the pump is about a half an inch longer than OEM and does not allow the bottom cover to fit onto the pump housing.

Fits perfectly. Well packaged. Had to swap electrical plug but they even included the one needed.
