Do we have a fuel filter?

[Corpsman]

I am approaching 70k miles and trying to do everything I need to do for preventative maintenance. With this economy I don't think I will be replacing my Si any time soon. I did a fuel tank SeaFoam and am trying to figure out where to do the intake with SeaFoam, and will SeaFoam the crankcase when I get ready to do my next oil change.

I was wondering if we have a fuel filter that should be replaced and if so, where is it?

Don't waste your money on that stuff! If you're using a decent motor oil and a decent filter and changing your oil at least as often as the MM tells you to do it then your crankcase probably looks pristine at 70k miles! Really, 70k miles isn't much at all unless you track your car every weekend or you run the oil 20k miles, etc. If you're putting in decent fuel you also shouldn't have any problem there. A bottle of fuel injector cleaner every oil change or so won't hurt, but no need to do all of the stuff you're doing. You can actually be doing more harm than good!

I don't think we have a fuel filter but I not within reach of my factory service manual at the moment to check on this. I don't remember anything in the service schedule.

What you need to be doing is changing the coolant every 3-5 years (don't flush it!) and keep an eye on the condition of your hoses and belt, flushing the brake system with fresh fluid at least every 3 years and keeping an eye on how much life is left on your brake pads, drain and fill the transmission maybe every 30-50k miles (DO NOT FLUSH if you have an automatic for those non Si owners that might read this!). These are some of the little things that can sneak up on you if you don't stay on top of them.

It can be replaced, but it's in the fuel tank.

Thanks!

-_- who the f puts it inside the tank? ppl make it hard for us GAH!

[00devo00]

umm car manufactures have been doing this for many years. this is because they don't actually need to be changed as often or at all. usually it will need replacing when the pump need replacing.

also its not necessarily meant to make it hard for you. it just has no more need to have it just hanging about under the car. plus it makes me more money when someone wants its changed (fyi im a mechanic) lol

Yeah I'm with devo here on the fuel filter. Leave that **** alone. Nothing sucks more than dropping a fuel tank to replace a fuel pump or filter for that matter unless totally necessary.

If anyone wants to change it, look at the DIY for the CTSC, it shows how to access your tank.

Couldn't have said it better myself!!

I would also advise not running your gas tank near empty as that will only make things worse for your fuel filter when all the dirt on the bottom starts getting stirred up.

[bro2snakeaterblk08]

How much dirt can get into the tank? seriously...

I've been running my tank to no bars (zero) since day 1. I drive about 10-20 miles are the last bar disappears and still fill up with less then 12 gallons, so that means there's 1.3 gallons left.

But seriously, how much dirt can there be in a new Si?

I remember when i drained the gas tank on my 92 Prelude, there was SOME metal bits that came out, but that can was 17 years old and has 6 owners.

You're right. The fuel pump is picking up fuel from the same spot in the tank no matter whether your tank is full or empty so any dirt is just as likely to be sucked up either way unless it somehow happens to be dirt that floats on top of the fuel rather than sinking to the bottom or mixing in. The only theory I haven't evaluated is whether the fuel pump needs to be submerged or splashed by enough fuel to keep it cool. At any rate, I run my down to a gallon or so a lot of the time and did so in my previous Accord and Civic that both made it past 100,000 miles before I got rid of them and never had an issue (that Accord is still driving around with a good deal more miles and still having no problems with the fuel system). Sounds like urban legends to me.

Provided you always use quality fuel brands and might have minimal dirt in your tank, you might be so lucky to run near empty and never find a problem for the life of the car. But for the unlucky souls who do somehow end up with a lot of dirt/debris in the tank, why make things worse by giving the dirt a chance to get sucked into the fuel filter?

My point is if there is dirt in the tank, it will settle on the bottom and if you get to a point where you are sucking up the gas near the very bottom, there's a chance you will also suck up the dirt with it. Sure, your fuel pump will probably pick up any potential dirt as it floats around the fuel but the most concentration of dirt is when you have lower levels of fuel, so you have more of a chance to suck up that dirt when you are low.

Of course, this only applies if you have a dirty gas tank. Urban legend or not, I rather be safe than sorry.

^^ lol at "legends" I highly doubt that fact that gas is that dirty to the point where it ruins the car. Not to mention dirt doesn't float, so more than likely we all are "sucking" up dirt. I am sure the is fuel sucked up somehwere at the bottom of the tank...thus means dirt....if there is any.

Also if there was that much dirt..I highly, and I mean really highly doubt these 15+ years old Honda's will still be running....fuel filters will be soo dirty that the car cant run no more..

beaters = using crappy gas

I'm with you all the way. I don't think mychee understands enough about how the system works. He could always modify his tank to add a sump like you see on gasoline piston aircraft and drain the "dirt" (you'd probably come across more water than anything). Then he'll never plug up his fuel filter!

[mychee]

You guys are going off on a tangent here. I only say dirt to mean anything such as particles, debris, rust, gunk, etc., but it's easy to just call it dirt. I think you guys are taking the word dirt too literal.

But I think you're missing my main point. If, for whatever reason (and I don't care how it got there but say it is there), you got dirt (sorry, I can't seem to think of a better word for this) in your tank, it's likely gonna be settled on the bottom. Are you guys saying regardless if you have a full-tank or near-empty tank, if you got a dirty tank, the same amount of dirt can clog up your fuel filter?

Then does anyone care to comment on the following link? Are the people answering the question blowing smoke?
