Changed my 2 micron filter this weekend and look at what come out of it.



I have a 5 micron in the stock canister and a inline filter that is before the lift pump. How did all that crap get past 2 filters? Some of the stuff that came out looks like small pieces of rocks. There was even a dead bug. I would HIGHLY recommend that you guys invest in aftermarket filters. If that stuff had made it past my 2 micron filter I would have been in trouble. Anyone else noticed this before? Im thinking the junk came out of my stock canister the last time I changed that filter.

You sure that stuff wasn't just stuck up in your drain hose?
Drain hose? The junk came out of the big 2mic canister filter. I poured out what fuel was still in it when I changed it and thats what came out. No hoses were needed.

I meant did you drain the canister with the hose when you changed the filter? How did you pour it out if it was already upside down when you pulled it out? I'm not trying to question your ability, just curious.

When i changed the 5 micron filter in the stock canister yes I did drain it before I pulled the filter out. But the filter the junk came out of was my 2 micron that is attached to my frame rail and it goes on just like an oil filter would.

Could that stuff be the result of bacterial growth. I see you are in TX, hot humid weather grows bacteria in the fuel. Moisture in the air condences in fuel tanks and allows the bacteria to grow.

Yeah good point but this stuff was dirt and small pieces of rock. No signs of bacteria as far as I can tell.

got it done right after I bought the truck. The guy that owned it before put 17k on it without the fix. Could have been from him I guess...

Well.....
The 'window' screen on the bottom of the sending unit inside the tank would keep this stuff from getting out of your tank (And it plugs up and shuts off fuel to your engine!). I see you have a Walbro, so maybe you have a alternate draw straw for it. ?
What I wonder is if it was on the top of your filter and there was a way for it to get into your catch container without you seeing it was outside the seal of the filter as you removed it. To see exactly what I mean: go look at the oil filter on your engine. You can see that there is a lip on the top that is outside the seal that can catch and hold crap like this. It is almost impossible to wipe off before removing the filter. Just a thought.
Also, I don't know which filter you have; but, the center hole should be clean fuel out of your filter. That junk couldn't have come out of there without catistrophic failure of your filter. The outside holes should be where the dirty fuel goes into the filter and most are made such that it would be hard for stuff like what you caught to get back out those holes. At least very easily.
This is why I vote for it being on the outside of your filter canister (Probably on top just outside the seal). I re-routed my OEM filter drain with a longer hose and I even put a cap on it to keep the inside of the hose clean. This way, anything that comes out of my filter drain should be from the filter itself and not outside. I keep what I drain to let it settle; looking for crud and water....

Those rollover valves mentioned are 1/4" hose barbs. I don't think stuff this big is going to get into your tank this way. They do leak; but, not this badly! Also, the 'fix' tsb is to just put on about 6" of hose.... I don't care for their fix. I have pics on Picasa Web Albums - Dan - Tank Removal ...
of how I fixed mine......
I was really shocked to see how much crud was in my tank when I pulled it. I believe it was in there from the factory. I don't know for sure; but, some was metal shavings and plastic shavings. I think it was from manufacture of the truck. I think it just shows how important it is to use great filtration!
It would be nice to know where your 'crud' came from. Look it over and see what you think about my 'theory'. It would also be nice to cut open your old filter and see what was inside of it. If you don't want to do this, I would be glad to if you can send it to me. I would also be happy to post pics of what I find.
hth,
