Hey Brian, did you change the fuel tank's filter, or the fuel pump's filter?

if you do decide to replace the pump you should change the filter/sock while your in there. if you look at post # 55 from the first link below you will see you have to undo the sock to GET to the pump so why not change the filter while your in there?

IMHO change them both its like $10 bucks and worth it....again look at post # 55 and you will see the difference in my used filter and my new one. ITS A SIGNIFICANT difference

oh, sorry i need to put my glasses on, i thought you meant to change the fuel pump not just the fuel pump FILTER..

Agreed and after that $47 quote from my local dealer just for the pump filter, I ordered both online and it was still cheaper.

nah, mine was CHEAP....like $35 bucks but i cant say that is typical, thats why i said i MAY have a fix for you
well since the gs400 DOESN'T have a drive by wire system you really cant relate here....
all in good fun 
your probably right though....i probably did jump to a conclusion but i still maintain part of the problem he was noticing is the drive by wire issue. Until you own a gs430 (especially coming from a gs400) you will never know the annoying pain we go to with the drive by wire systems
im with you though, OP def needs to search
im with you on this, when i first joined the boards for like 2 years i swore the filters were lifetime when people asked about them, then that post came up and i was like DAMN.....needless to say, i changed mine shortly afterwards and it made a huge improvement to my MPG

, driven both and own a 400, the drive by wire lag is nothing compared to a bad fuel filter/pump. To the OP its a 20 min job to check if the fuel filter is bad or not, and 15 of those 20 min is just pulling the back seat out.

Okay- Just scanned it again, Brian. It did not pull any of the codes you mentioned-
P0040 , P0441b, or P0446b
It pulled up code P0171 - System too lean Bank 1
and it said PENDING on P0174 - System too lean Bank 2
Maybe it is a fuel filter.... or could be the MAF needs to be cleaned (hopefully not REPLACED!)
You have to remove the back seats to replace the fuel filter ? I need to search how to do that. Sounds like a pain.
What was the $47 for? I'm confused on replacing the pump's filter.. that shouldn't need to be done, unless I was replacing the pump (b/c it went bad) or something, right?
We turned the Check Engine light off. Now, when I take it into the dealer for my stae inspection, should I ask them to replace the filter- or is it easy and simple enough to do myself ?

awesome thanks... Can't wait to find out which part is causing these codes (and hopefully the 'bogging' when I get on it, initially)
Thanks so much!
Forget the Pump's filter though, right? The actually fuel filter... is under the back seat, right?
I will follow that DIY thread and replace that.. okay.

BOTH the fuel filter and the fuel pumps filter are located together (you have probably heard us referring to the fuel pumps filter as a "sock")
replace BOTH of them while your in there...
