Yes, I've heard this many times before. I too like USPS...but not when a package doesn't get delivered. It's quite the undertaking to research and discover who, when and where a package was delivered. Whatever the case, it's still on the forefront for integrating their shipping options to our shopping cart.
I appreciate all the business!

Funny Brian, you say confirmed, but either our weather is bad, or I've had a heavier foot, or I've been running the heater (ac comes on with it automatically) more, so maybe those are all taking negative hits to it. This fillup though seems alot worse. It's halfway between the 3/4 and 1/2 mark and only at 125 miles......that's garbage imo. True test will be though, as long as I don't get sick, from Jax to Monticello(GA). Last time I got 25.6MPG out of it, if I get less this time, then I can't say changing the fuel filter helped.

I just did this today.
1998 Lexus GS300, 90,000miles. Have only used top tier fuel (chevron/shell) from high volume stations for the lifespan. half-bottle/dose Redline Fuel Injector additive once/year prior to oil change.
The bag looked pretty much clean except for a few grains of grit and some stain. Did not hack up the filter and have not driven to be able to tell if a difference has been made.
The peek into the gas tank also looked perfectly clean too, despite the urban legend saying keep your tank full otherwise you'll be picking up crud from the bottom of your tank and clog your fuel pump..
I do have to say I did run into some trouble in having to do some different order of things in the disassembly as compared to Sakataj's post, probably due to model differences.
In particular having to take the bag and fuel regulator off first before the pump can be removed from the support housing. And I also forgot to put in the filter cushions (bumpers) during reassembly, so had to do the procedure twice.
While the images in his DIY are very nice and appreciated, I recommend DIYers to also review and read the disassembly and reassembly steps in the service manual:
From the DIY sticky: http://bahamutcars.free.fr/workshop/...nts/index.html
look under fuel pump with a sublink to fuel pressure regulator.
Now that I've gone through it and made mistakes, I see that the service manual has the right steps and order. The only deviation I notices is there is a plastic piece that is not listed in the service diagram. It is discussed in this thread:
https://www.clublexus.com/forums/gs-...ml#post5720062
However, after playing and thinking about it, I do believe the following image from that thread is correct.

Installing the o-ring onto the fuel port (not just on top) is what's mentioned in the service manual, then add on the plastic piece. In this configuration, the o-ring creates a snug fit between the filter tube and the suction plate tube with compression on the exterior and and interior circumferences of the ring (which is how most o-rings seal), and holds together just from that the compression of the tubes themselves.
The other way that Och mentioned where you just drop the oring in, and is compressed from the housing on it's top and bottom seems more suitable for a rubber washer/gasket which has has a flat top and bottom and expects to be compressed along those surfaces.
With a ring it may work enough so the car runs, but this counts on the ring circle lining up exactly with the fuel port circle and that the compression from the housing stays constant. Even during reassembly in this fashion, it doesn't stay together until you get the snaps done.

Not my link, it's from the diy sticky. There's a couple alternative manuals in the sticky too.
Even on pc it only works with very specific browsers, specifically IE. So you might get it too work just by trying more browsers
