My fuel pump is buzzing and noisy under the car and seat. I will have someone to do the job. What do I need to order? Couple examples. Fuel pump Lexus part: 23221-3134 for around 300$ from lexuspartsnow.com or Delphi FG1174 for 181$ from rockauto. Thanks

 

Personally I would order the oem Denso part, but not from lexuspartsnow as they literally don't have any customer service. Check some dealerships like Bell Lexus, they usually have coupon codes you can use. Or order oem from rockauto

 

Thanks. Do I need the whole new assembly in addition to electric pump or can I reuse the old one?

 

That I am not sure about. Someone more knowledgeable than me will hopefully weigh in

 

Depending on how bad the module housing is. I'd opt to get everything new at that milage. The fuel sender is incorporated into the housing. These senders get wonky at that milage. You can clean the sludge off the tick marks, but if the ticks are scraped up. I'd replace the whole housing.

Check the o rings. Get new sock pre filter for pump, and fuel filter.

Here's a thread I made for changing the fuel filter. The links include photos from other models. Most Lexus fuel pump assemblies are similar in fashion.
