Rx400H Fuel Filter Location/r&r/replacement


Recommended Posts

I've had several fuel pump failures on other vehicles in the past few years. In each case I also R&R'd the fuel filter at the same time, cut the old one open and found it to be filthy. Also a trusted mechanic has told me that dirty fuel filters can in fact cause fuel pump failures due to increased back pressure.

That being said I can find no reference to a fuel filter on my RX400h. No replacement interval and no location or removal instructions.

Can anyone shed some light on this?

Had a RX300 with 189k miles and never changed it. It is sort of self cleaning as it is in the fuel tank. I wouldnt sweat it.

Thanks, gentlemen. I followed up with a Lexus service manager and got about the same information. He called the fuel filter more of a "strainer" which is never replaced other than along with a fuel pump failure. I still find a "strainer" odd since conventional fuel filters trap very fine particles to obviously avoid engine damage.

If it ain't broke I won't fix it.

Thanks again.

Don't consistently run until almost empty and you should be fine. My brother-in-law's Toyota van had over 300,000 miles on it and I believe he never changed or had the fuel filter changed.
