Lifetime fuel filter......Haha ya right
Well I got around to changing my fuel filter today. The parts manager at the dealership argued w/ me about it when I tried to buy one. He insisted it was a lifetime filter! Yea right! I pulled it apart, the filter element was completely black. I think this was the original filter.....about 75,000 miles on it. After seeing that I'll be changing it every 20k. Lifetime filter....geez.....until your fuel pump takes a dump, then its not lifetime anymore...

If they were lifetime, I dont think every parts store wouldn't ahve them in stock. I just do the NAPA gold for like 20 bucks every so offten. Cheap insurance for the pump!

I do not get it??
2 - Just because the filter media is dirty, does that mean that the flow is necessarily impeded through the filter and the fuel flow/pressure is below spec at the rail?

on the older trucks 94 etc.. there is 2 filters. the one inline filter that is on the frame rail and the one on the inlet to the fuel pump.
this first intank filter looks like a small silk bag. very fine and clogs very easy. i would recommend if you are going to replace the inline filter i could drive the truck around and get the tank close to empty and drop it down a bit (or take it out) then remove the fuel pump and replace this intank filter because if your inline filter was bad this one will probably be so clogged that when you take the pump out it will hold in the fuel and not drain.
alot of work but worth it. make sure the batt is disconnected. good luck
make sure the truck has the intank filter first but i dont think they would change their fuel set up.

Is there a how-to on changing the fuel filter on this site? Just curious to read about any possible PITA scenarios. I have a new filter sitting in the garage I need to change.
I've got a new trans filter I need to change too, I've decided that no matter I am going to run the Toyota Trans fluid, it's a little more expensive, but with the money I'm saving doing it myself I'm not too concerned.

Given that toyota calls it lifetime...
Ii would still like to see some evidence that some dirt/discoloration in the filter means that it is no longer 'good' and that it may reduce the life of the fuel pump.
Would the test be fuel pressure a the engine?

Yes, but the problem would be getting the pressure reading at highway speed or under full load conditions. Just because the filter paper is black doesn't mean it won't flow properly any more than a dirty looking air filter might still flow fine too. It's just a part of basic maintenance on a vehicle and you change it at an interval you feel comfortable with (my service interval on a fuel filter is not the "lifetime" of the vehicle however).

I changed mine at 100k but still question why. Dont we look to the manufacturer for maintenance intervals all the time - so why not believe toyota here?

Why does Toyota's maint chart from the owner's circle have an oil change listed every 2500 miles? I guess it can't hurt to change it, fuel stations have dirty tanks and crap comes off the inside of the fuel tank well so it's reasonable that the fuel filter will need changing at some point.

This article sums it up well:
"The following story has become folklore in repair circles. It is about the Toyota lifetime fuel filter. It was almost 10 years ago when Toyota proclaimed its fuel filter never needs replacement. How could that be, since it was an external metal can? Seems as if the warranty claims on some makes were very high as the lower nut was overtightened at the factory and a new metal line from the tank to the underhood filter was commonly damaged. Since then the filter has been a hands-off item. Makes one wonder."
Even Gadget has chimed in on the same subject only to confirm the same thing I am saying now.

It gives me a warm and fuzzy knowing I have a nice clean filter....for now....
I could see particles and debris on my old filter element after I ripped it apart, must of had some nasty gas.

Lifetime filter... then does that mean the gas I put in my tank is 100% clean and pure? I think not. I did mine awhile back and there are even threads where people have pictures of their fuel filters cut in half to show the dirt inside. I'd rather pay a few bucks for a filter than a few hundred for a new sending unit.

I hope there's dirt in the filter when these are cut in half since that's what should be found in them but I agrre after at least 100k I'd change it but there are plenty of Runners with 200-300k on the original filters still going and I haven't read that a filter has caused engine failure. If it gets too clogged it'll just hurt performance.
