My first job was working at jiffy lube changing these things out, its all a waste of money if you ask me. I had an old MX6 that never had it changed in like 150k miles. I changed it for the heck of it and never saw a performance/mpg difference.

 

if you guys had remembered to A-use up 3/4 tank of gas so there's not much left and B-open the cap to release pressure, you would have had a better time

 

I'm still burning on my back i will b taking it to the corner shop to replace it i have the filter so it shouldn't b much......

 

i opened the cap and release the pressure but the tank had a half of tank full of gas.....

 

If you will read the complete procedure, the correct way to do this is, before removing fuel filter, to disconnect the power connector to the fuel pump and then crank the car and run it until it stalls, this will remove the residual fuel in the line that would otherwise be raining down on you.

 

The reason why the fuel filter is for "Lifetime" is because there is another filter called "suction filter". This filter is on the bottom of fuel pump in the tank. No dirty will pass thru this filter which make the fuel filter to almost do nothing. if you ever want to change a fuel filter, i would change the suction filter.

 

Not exactly.

The fuel filter is designed to filter a much smaller particulate size than the suction filter. So both have their place, but the suction filter basically just keeps the big stuff (big being a relative term) out of the main fuel filter, but it doesn't make the main fuel filter redundant by any means.

if you doubt this, here is an experiment you can do - take a new suction filter and a new fuel filter to your sink, get some muddy water and pour it through the suction filter, any debris will be caught, but the water will still be muddy looking coming out. --> now take the muddy water that came out and run it through the fuel filter and it will come out looking like clean water or at least much cleaner and no longer muddy.

 

One thing I have not seen are the external filters cut open after removal...well, rightly so containing gas. Still, I would be very curious how fouled these are on stateside cars.

 

Toyota designs the inline fuel filter to be lifetime; it does not appear on the service schedule for routine replacement. Depending upon the configuration on the particular vehicle, one may well find the fuel line will not loosen from the filter without damage, and the line will have to be replaced. Happens from time to time in Toyota dealer shops. All of that said, I think it is a reasonable idea to change the filter every fifteen years or so.

Never ever use teflon tape in a fuel system. Tiny strands of teflon can break free and cause havoc. This best practice is well known to aircraft mechanics where such things are super critical; less so to the automotive crowd. There are gasoline resistant sealants suitable for fuel system use. They are hard to find, but they are out there.

 

True, it will not clear the fuel which come down to, it depend where you get your gas from. We all know the gas refining process which involve distillation. So gas comes clean from the factory until it reach storage tanks. Old gas station may have rust tanks but now there are regulations on how to build storage tank, 18 wheeler have aluminum tank which are rust free, old cars may have rust tanks but not our 400. I don't see how gas will get muddy dirty.

 

Not sure of that year but maybe its in the tank
