REPLACE YOUR FUEL FILTER AT LEAST EVERY 100K. It is NOT a lifetime filter as Toyota claims! (if you get rid of your car at 100K, then I guess it is... )

Holy %&&$$#!!!! I just did my fuel filter in my 99 GS, 145K miles. Did the bag and the larger filter. Chirping tires now. Pis$es me off cause I would have done it 50K ago if I had known. The car has seen nothing but 93 octane in its whole existence, yet apparently that didn't prevent the filter from slowly clogging.

It's been running pretty badly, even was stalling on the road. I started doing a lot of maintenance items: spark plugs, cleaned air filter, MAF and throttle body, PCV valve, added Chevron Techron. That helped a lot of it. But whoa!...I did the fuel filter, and now it's back to being a race horse again. I'm gonna do the coolant temp sensor as a last item.

Doing the filter replacement is NOT for the faint of heart. I'm an engineer and weekend mechanic, and the only jobs that I fear are those where something can crush me or something can blow up. This job had me spooked cause I don't normally work around an open tank of gasoline, and I was afraid of creating a spark. NOT a very fun job, but necessary. If you're the least bit tentative on this one, take it to a shop mechanic.

 

good to know. why does lexus say the fuel filter lasts the lifetime of the car?

 

I haven't changed my fuel filter yet, but it's probably bad but not enough to stall the car. The car still runs like nothing ever happened. Car still burns rubber as I wish. I guess just depends where you get your gas from. If the gas station got filthy gas containers than it's all going into your tank. Can't prevent that.

 

No idea, PushinLex.

Fiend, you may find that you're ok up to a certain mileage, but then it starts going to hell quickly. Mine got a lot worse in a matter of a few months.

 

good to know! did you go with the OEM filter?

 

there is a diy on here..pretty easy to do when u look at the pic to see what to expect.

 

someone had a hard time just because of a simple O-ring that is almost impossible to get.

 

Why would you blow up? or even give the perception that changing anything along the lines of the Fuel system will automatically result in an explosion.

If you follow COMMON sense procedures you can change anything.

 

Why would 93 octane prevent a fuel filter from clogging? Do you know what an octane rating is?

I'm guessing your S/N has nothing to do with your occupation...

 

Guys back on topic please

 

 

what is hell mileage? i get like 14-16 mpg, and iono why..

 

Sounds like city driving to me which is normal.

 

im @ 130k and it drives fine.. i smog my gs myself today and it ran pretty dam clean... HC (hydro carbon) 5 @ 15mph and 7 @ 25mph... bet its gonna last til my engine blows up hhaa or until my chit falls apart

 

i bought the filter from rockauto but what about that little bag where do i find that?
