Original fuel filter?

Original fuel filter?
So I went to my local Grease monkey this afternoon to get my fuel filter changed.After 2 guys and 45 minutes they finally got it off,spent about 15 mins. putting the new one on.The main guy working on it told me it looked like the original factory fuel filter because of all the rust and difficulty getting it off.Only cost me 55$ to have them bust there knuckles.My question to every one here is : Is it possible for a fuel filter to last 19 years?

I don't see a service interval for the fuel filter in my service manual, although I bought my spare a long time ago when I thought that it needed changing as part of the normal service interval. As I said earlier, it does come down to whether or not the gas you buy is clean of any debris. In this case you don't want to replace filter on an interval as much as you want the new filter and the correct wrenches in the truck should the one on the fuel line get plugged. You can sometimes get a bad tank of gas out in the boonies, resulting in a plugged fuel filter.

Better no money person drives all the time on 1/4 tank or lower takes out his 3rd fuel pump and has no clue.
For what it`s worth i sure would not want to change a fuel filter in the stock location any where but in the shop
With the filter where it is I can see them being on there 20 plus years

Hmmm...so why do all new vehicles have scheduled fuel filter change intervals in the manuals? So its a crap shoot with fuel because Ive got crap fuel at so called good service stations and had to change the FF.

It is possible to get contaminated gas at a gas station. The station's tanks may have some water or other contamination at the bottom. Remember, water and dirt are heavier than gasoline and sink to the bottom of the tank. Not a problem unless that stuff gets stirred up. When the tanker truck delivers a load of fuel to the station it stirs up the tank. When you pull in to get gas and see the tanker delivering, drive to the next station.
I had a gas station, and we checked the fuel level in the tanks by "sticking" the tanks each day. We inserted a long calibrated stick down to the bottom and read the gallonage from the calibrated sticks. Periodically we'd put a small dab of water detecting paste on the bottom of the stick. If it changed color, there was water. I never found water, but I don't know what else was in there.

Point is, that gas was horrible. I now try and stick with newer gas stations.

Yeah I gladly payed it after watching them get frustrated working on it for an hour.I knew it was a SOB just from reading this forum for past 3 months.I got comfortable in the waiting room and watched through a big plate glass window while 2 guys worked on it.Knew I would be there a while.

I worked for Toyota in parts for years. The Toyota fuel filters do not have a change interval because they were never intended to need changing. We use to get TSA from Toyota all the time about not needing to change them. Old school service people use to include it as parts of the maintenance on them and Toyota made it clear it was not need till over 700K kms. That is of course depending on the quality of gas being used at 100k kms (the normal fuel filter change interval) the Toyota filters would still be flowing something like 98% of its intended flow rate. They put a ton of research into it in the 80's.
I had to change mine on my 4runner after 340k kms, but that was because I got dirty water in the tank.

i couldnt take my filter off i was like screw this. on this site somewhere someone stuck a different filter in from like a ford and put some plastic lines to the fuel lines

I just cut mine out and replaced the hard lines. The hard lines had corroded to the fittings and turning the fittings twisted the lines.
Interval? Either way, cheap piece of mind to know it is not an issue, especially if you are not the original owner.

I don't get it, you say that the Toyota filter doesn't need to be changed until 700K kms or 435,000 miles, but the normal filter change interval is 100K kms or around 62,000 miles.
So does it not ever need to be changed or does it need to be changed at 62K miles?
I don't see how they can invent a filter that never needs to be changed, but not put it on every car they make and how other manufacturers don't use the technology.
I used to work for Nissan and all fuel filters had a service interval of 30K, and let me tell you when they came off and got dumped out, what came out was filthy.
ALL gas has contaminants floating around in it. You don't just have to get a bad batch of gas with water in it (a filter isn't gonna do anything against water anyway) or gas from a station that just got filled from a tanker.
How do you think the so called stuff on the "bottom" of your tank gets there? It's sediment from all the crap that is in gas, constantly floating around in it all the time. This stuff doesn't just sit on the bottom of the tank and get sucked up when you go below a 1/4 tank, the tank is in a moving vehicle with gas in it constantly swishing around, all that crap is fully imersed in the gas all the time, as soon as you get down your street it's off the bottom and fully immersed. If a filter wasn't constantly neccesary and constantly filtering, then they wouldn't put one on at all.
That's like saying you only need to change your air filter if you drive in the desert in sand storms.
Go fill a 2 gallon gas tank and then dump some into a glass jar and see how clean it is, it isn't.

Toyota uses what they call lifetime fuel filters. That's generally why they mounted them in such PITA spots. For example, my MKIII Supra uses the same type as my pickup (but the mounting is different, IIRC), on the truck, it's tucked away under the intake manifold. On the Supra, it's located above the differential. Both spots are a b!tch to get to.
For what it's worth, I changed out the filter on my Supra when I put a high volume pump in, at 160k it looked perfect inside. At 155k on my Pickup, I did the headgasket (22re)- filter looked perfect inside. I replaced both anyway, as I'll probably never have to replace them again. Both were original.
Edit: I should mention that I didn't just look in through the holes of the filters, I actually cut them apart and examined every fold.

I changed mine out on my 91 pickup, from the original Toyota filter with 280k miles on it, when I had the intake manifold off doing some cleaning, and the only reason I did it then is BECAUSE of the fact that it's such a PITA to get to, and with the intake off, it's literally RIGHT THERE in your face
I then changed it again, 16k miles later, when I pulled the motor and rebuilt it from the ground up; but I replaced a LOT on that motor at the time; the fuel filter was the least of my expenses, lol

I was referring to other manufacturers normal change interval (30K in Nissan's case)

Toyota did put that into every car they made in the 90's as far as I know, may still not sure.

Sorry did I say anything about a filter offering any protection against water? It was the mud and silt that got in my tank along with the water that prompted the change in filter,fuel pump and strainer as well as a flush and reseal of the tank.

Um OK I did not say a thing about not running under 1/4 tank to prevent bad gas getting picked up. I am well aware of the way fuel acts in a tank and the way the contaminates acts in a tank.
That's like saying you only need to change your air filter if you drive in the desert in sand storms.
Well you can do that if you want but I change my air filter regularly.I never said anything about air filter or any kind of change intervals on them.

I'm not saying and have never said that gas is clean, you keep rambling on about things I have not said.
