Hello everyone, I just picked up a 2003 GS300. I put my first full tank of gas and noticed that it was leaking under the driver's side rear tire. I pulled the rear seat and pulled the entire fuel pump module assembly and discovered the plastic "top hat" (unsure of the name) portion of the entire fuel pump module assembly is broken. With it being degraded/broken, it's unable to make a good seal and fuel is leaking under my car. There was a Toyota part # 77020-30011 that I found on it. I called Toyota and Lexus and they do not have it. Where can I buy the just the "top hat" or the entire fuel pump module assembly? Below are a couple pictures where I highlighted the problem areas in red.

 

Try these part numbers from your parts dealer:
Lexus 77024-30040 - Plate Sub-Assy, Fuel Suction
Lexus 77169-33020 - Gasket, Fuel Suction Tube Set

 

Thank you so much! These are the exact parts I was searching tirelessly for. I was getting nervous that the top portion was an obsolete part, and I nearly purchased a used one that I found online. I just placed my order to fix my GS300!
