As I wrote a couple of days back, a perusal
of the shop manual indicates there is no
fuel filter in the IS system, other than what
I now know is called a "sock" in the fuel
tank. The sock is technically called a
suction filter, and is upstream of the pump,
and does not appear to be readily serviceable
except in a major repair.

I stopped at South Bay Lexus this afternoon
and spoke with a service writer, a mechanic,
and a man at the parts counter. After much
checking of the computer, they all agreed that there is no fuel filter between the
tank and the injectors.

The service writer suggested I call 180025Lexus and talk to one of the service
people at that number. I intend to call
tomorrow morning.

I discussed with the service people if they
would install an in-line filter, and they
all looked the other way and made noises
about high pressure pumps and spilled fuel
and fire, etc. They appear to see, probably
correctly, fuel filter and lawsuit both in
the same sentence. When my injectors clog,
is Toyota going to repair them at no cost
to me?

Is there any other Lexus model that does not
have a fuel filter?

I traded in a nice '92 Taurus SHO that had
a big filter in the rr wheelwell, and I
changed that unit every 12-18 months. I've
never heard of an injector engine, until
now, that didn't have a filter.

Can anybody shed some meaningful light on
this topic?????

interestingly enough, 1.8L fuel injected 16v Jetta's from the late 80's do NOT incorporate a fuel filter in the line between the tank, pump and injectors. No idea why as the 8v carbed did (i might be corrected). FYI

I just had a long and rather nasty chat with
a gentleman at Toyota in Torrance. He told
me that Lexus would NOT install a fuel filter
on the car, even if I paid for the parts and
the labor. He said if I installed a filter,
it would be outside the Lexus warranty, and
I would be responsible for any damage to the
car, leaking fuel, fire, etc. He said if the
injectors clog during the warranty period,
Lexus will fix them at their expense, and
if they clog after the warranty, it's my
expense. This is my first Toyota, and I'm
not bowled over by the engineering or the
after-sales courtesy and enthusiasm, all of
which are nonexistant.

Well, you can look at it this way... periodically, pour a can of fuel injector cleaner into your tank.

Gas are pretty clean these days so I don't think you'll run into problems with your injectors being clogged (I haven't heard any cases at all), especially if the IS requires only Premium Fuel (ouch!!).

I bought from a whole sale, 2 cases of Redline Fuel System Cleaner (48 bottles)... cost about $2.95 per bottle... and I use, along with my other cars, every 2 weeks...

Thanks. I do use some cleaner in the fuel
tank (usually Marvel Mystery Oil), and I plan
to continue doing so. I'm just dismayed at
what I regard as low dollar engineering by
Toyota.

Low dollar engineering by not including a 30 dollar part hmmmmmmm try thinking about that one alittle... you thinking.... keep thinking........ You just paid 30+ k for the car and you really think they excluded a fuel filter to make you angry...... hmmmm I think Lexus had some logic in that engineering design. I have had many cars and never had fuel filter problems( I cant remember ever changing a fuel filter excpect for a stang I had in 91 and that was a upgrade not a replacement) I always run 90+ octane and never use any additives except for fuel preserve when i store a car for the winter. I could understand the Ford company using fuel filters as many owners use the cheapest gas possible, but I dont think Lexus did not go with a 30 dollar fuel filter due to poor engineering.....

Thinking about this from a sales-driven frame...perhaps Ford "overengineered" that Taurus SHO of yours for a reason. Consider this....that $30 dollar filtered changed religiously every year is somehthing for Ford to make MONEY OFF YOU. Kinda like why they use inferior bearings in their alternators to design them to fail. Tow truck man gets paid, service man gets paid, mechanic man gets paid, parts man gets paid...etc. And they "get you in the door" to maybe sell you more service, another car, an additional warranty etc. etc. There's a reason for everything.....

I wonder if the Altezza engines have a fuel filter, just for the comparison.
