must share - small fuel filter makes big difference
my ls400 90 had long been having unstable idle and slow start-up (no matter engine is cold or hot)
I did a lot of guess work like replacing spark plugs, air hoses, temp sensor, ECU... didnt work.
last week I realized that I did not change fuel filter for 8 years or so
so I decided to get it replaced. and what a difference! idle is now so smooth, easy start-up in split second, and the car runs a lot more powerful.
small thing makes big difference. a must share.

however, I am thinking how we can safely cut the filter, its highly flamable

I've been planning to change mine but then read that they hardly get clogged up on the LS. However I already bought the part. And replacement doesn't seem to difficult. So long as I disconnect the pump fuse. Maybe in the near future

There are various non-powered hand tools but for sake of this, just toss it. We don't want any unintentional fires or injuries as a result of inspecting the filter elements.
Stateside gas is low in terms of free floating particulates. The station storage tanks may have some level of contamination but largely well maintained stations we don't have to worry. My mechanic has cut open filters at 100-300K miles and relayed he's not seen filter contamination. When I hit the change interval he just told me don't even waste my $ or the service. Other countries may have "dirtier" gas so changing the fuel filter is necessary.

many stations were investigated and found at least 10% cheat. you pay 100 liters you get 90.

to access the filter you would need to work from below, when filter removed, gas will keep flowing down until a new one sits in properly. be prepared for your hands, face, eyes, arms to get wet with gas. and this is extremely dangerous. I would recommend you leave this job to the professional mechanic.
1 more thing, if you have removed the filter and change your mind, your car is already out of service. you cant drive it to workshop anymore.
think twice

Maybe its just me but saying to not change a filter sounds crazy, these things arent built to last forever after time they break down and im sure they slow down the flow of gas and any contaminants in gas get trapped in the filter. Changing a fuel filter can be messy but unless you dont know what you are doing then your fine to change it. Just like any other fluid take what precautions are necessary so you dont end up with an eye or mouth full!!!!
