Adding an additional, aftermarket fuel filter?

Regular maintenance of a replaceable fuel filter is around 30k miles or so. The one in the 2nd gen is considered non maintenance. When you replace the pump you replace the filter.

A filter that requires regular maintenance is actually visiting the dealership more often than a self cleaning filter that will be changed maybe once or twice if that vehicle is kept for a very long time. Your paying more to do regular maintenance with the replaceable filter visiting the dealer.

 

I seriously have no idea where you are standing with this argument lol. The vast majority of people who own Tacomas alone have gotten hundreds of thousands of miles on their vehicles on the stock fuel pump and filter. The pump will break down and clog before the filter dies and let's large contaminants into the engine. Maybe after 100,000 miles of small particulate build up will your plugs be failing or have any sort of build up, but then again, if you're the type of person who doesn't do standard maintenance once in a while, you probably deserve your grenade engine.

Hey and guess what, if you're sooooo worked up about how crappy that filter sock is now, do yourself a favor, as I do, throw some fuel system cleaner in your tank about once a month, and presto!

Also, stop buying shitty gas. I don't know about you, but I put premium in my baby, and make sure to stay away from no name gas stations. Oh noes, I have to pay an extra 5-10$ every fill up by going to name brand stations, shoot, guess I better declare bankrupty.

Edit* Keakar, not moondance. I forgot to quote.

 

No doubt. If you're getting overly dirty gas, then its time to move onto a name brand gas supplier. There's tons of 2nd gens running around with shit loads of miles while still using the original pump, filter, and injectors.

 

maybe you should check your facts, all those tacomas with hundreds of thousands of miles on their vehicles on the stock fuel pump and filter HAVE AN EXTERNAL FILTER, plus they are told to replace it every 35k-50k miles because it gets dirty AFTER the gas has already gone through this magic sock on the fuel filter you are so secure in trusting.

geez you guys think magic pixy dust protects things go right ahead

and by the way, this is the first gen forum where EVERYONE here has external filters and if you guys dont think they are needed for your new trucks I don't care, that's what warranties are for but this forum is for trucks that use external fuel filters so lets stop highjacking the thread with this "my new truck is different BS".

 

Pixy dust? Your the one that can't except that a truck that has a different filter system isnt reasonable. There not magic, they exist. These trucks arent breaking down because of a lack of external filter. Lol.

 

Yea, Touché, I didn't notice the forum was 1st gen. But still, once the topic was brought up, you're the one thst fought it so hard and now that we've thrown facts in your face, you want to back pedal and say it's for first gens. Ugh. OK well, I'm done, seeing as how I have a second gen with a worthless sock for a filter that I haven't changed in 70k miles. Engine is probably one big charcoal briquette at this point.

Oooh man. Good times, totally couldn't remember what that was from. Well played, Sir.

 

Adding another fuel filter just means you now have to change two filters instead of one. I've rebuilt injectors once on my 85 4runner and it isn't that big of a deal but needed to be done because of how old they were and more so because previous owners failed to replace old filters. I think if the filter is replaced when needed the injectors will tend to stay clean and functioning, and like someone else stated you can add a fuel system cleaner every now and again to keep things clean. But maybe the gas here is cleaner then where you are, I don't know. I do know that I have original injectors and over 250K miles and one fuel filter.

 

first, the only FACT you have is you managed to go 70k miles without issues so far and that your truck wasn't made with an inline fuel filter between the fuel pump and the injectors. im sure some manage 100k or more without issues but that just proves you can get lucky just as others never change the external fuel filter and drive 300k miles without injector issues so anything is possible but it doesn't mean its a smart thing to do.

secondly, I never "fought it so hard", I simply said it was hard for me to believe they would remove vital engine protection. that is a simple opinion and not a topic of debate I need your approval or acceptance of. it was you two guys who could not accept there was indeed a benefit from having extra protection and your trucks no longer have that.

then YOU started making claims of "all they need" is a sock in the gas tank to protect the system and don't need inline filters, which is proven untrue time and time again to cause dirty fuel system issues in every system in has been used in but that is beyond you.

that is what I tried so hard to convey, your opinion that having inline filters is not a better design then not having inline filters because it is basic common sense that more protection is always better then less protection.

I never backed off one bit, but you feel the need to somehow make this false claim to distract from your losing argument that inline filters between the fuel pump and injector rails are somehow not a better design then nothing but a sock filter before the pump and no filter protection after that point.

just because your trucks are designed differently doesn't make them better or fuel systems run as clean. by your logic they should also remove the fuses in the fuse box because they are not "required" either.


lastly, I never said the sock filters in the tank were worthless, they are there you catch large particulates before they get into the fuel pump and they do this job well but they do nothing to stop small particulates from flowing into and past the fuel pump into the fuel system where there is a need for an extra filter to trap these particles yet on your trucks this extra protection is not there, period.

boom! wham! bam! zing zaroo and all that other childishness you like.

 

i wasn't saying we need to add another fuel filter (although I did say it could be done if a person wished to), THEY were saying you don't need your fuel filter at all simply because their new trucks don't have them.

I agree with you that changed regularly all we needed is the one inline fuel filter we have because we also have filter socks in the gas tank on the fuel pumps (just like their new trucks do) as well as we filter screens built into the injectors themselves so there are 3 levels of protection built into the system.

 

Yeah, I was mainly referring to the OP's comment about adding an additional fuel filter.

 

Sure I'll jump back in.

Let's get the 2nd gen stuff out of the way first. 2nd gens like 1st gens have a sock, screen, filter, what ever you want to call it, on the pump intake. They also have a filter after the the pump. Some consider it to be on the small side but it's there just the same. The major beef is Toyota considers it part of the pump and it's not sold separately, then there is the fact that it's inside the tank.
Toyota also feels that both the 1st and 2nd gen filters are a lifetime thing with no scheduled change interval. Yea, sure. Maybe in Dilberts cubicle but not in the real world. The only way to provide some degree of reliability is to change it out now and then as PM.

Bad gas? These days it's pretty rare. Of course it happens, one doesn't have to think much beyond New Orleans and Hurricane Katrina to see that.
On the other hand, of the 3 fuel pump jobs I have done on 1st gens with between 150K-200K miles, the tanks were absolutely spotless including the pump filter. Not one grain of grit or flake of corrosion. That includes mine after drinking Pemex for a month. FWIW the 1st gen intake filter rests all the way down on the bottom of the tank and leaves a little polished spot as proof.
Then there's the whole Ethanol thing. While it has it's drawbacks it does mix with water and the resultant mixture gets burnt with the gas instead of the water collecting at the bottom of the tank.

Multiple inline filters? Pointless, unless they are progressively finer. If not the first filter will still catch all the crap.
In the Marine industry we frequently used the "staged" multiple filter approach. The first being a combination water separator and "screen" followed by a true filter.

The crap everyone finds in the filter.
Outside of foreign contaminants, a good chunk of that dark brown/gray shimmering almost metallic soup that dribbles out of an old filter is the worn off debris from the fuel pump brushes and commutator. Catching this crap is half the filters purpose in life and there is more of it than most would think.

1st gen OEM Denso pump at around 175K, working perfectly.
Nice polished and balanced armature, but check out the depth of wear on the commutator plates.



Just for giggles here is the pump portion. Really good example of modern precision die casting.

 

I never said anything about the internal or external filter being better or worse. I simply stated the facts that all 2nd gen trucks dont have an external filter. Read your own comments above. You're the one stating there is some kind of conspiracy on Toyota's part to get engines to break down by removing the external filter.

And what is this about it being a new design. They've been doing this on all 2nd gen tacomas. That's the last 10 years. Plenty of people with over 200,000+ miles without burnt up motors and injectors due to this 'intentional deviant' design to get more people in the shop.

 

Pow, whammy, whack, PAH, zing! Couldn't have said it better myself.

To get back on topic, OP, a secondary filter for you would be quite worthless. Just make sure to change your in line filter, whenever you start feeling like it needs changing. Every 100 milrs, or every 10k miles or every 100k miles. whatever.

 

this is true, moondeath I never implied or said that it was YOU who was promoting this false narrative. I did in my reply to your statement state my opinion that it was not the best design to delete this filter.

this is when tweetle dee and tweetle dumb got offended and had to defend the design of their new trucks and try to claim im making wild claims of massive truck failures and exploding engines just because I correctly stated how removal of this extra filter can and will cause fuel systems to run dirtier.

 

thank you,

BOOM !!!

game set and match !

but im sure VolcomTacoma2011 will still try and argue with THAT

VolcomTacoma2011 you can crawfish all you want but your whole reason for arguing through this whole thing was to dispute my statement that it is better to have an inline filter on our trucks and it provides an added level of protection that is needed. all the rest is you just blowing smoke.

 

How is that game set match? I was arguing the fact that our single sock filter is fine, and he just proved that point. Clearly you have confidence issues here. Moving on.

 

I'm not entirely convinced that you were truthful when you made your profile and clicked 'male'. The only people I know that make my argument their own and then try to shove it my face that they are right, are women.

 

"Single sock filter"? I'm not on anyone's side here but you should go back to post #33, read the first paragraph, carefully.
