hello i figured if i was 93 octane it would clean the fuel filter out better why should we change them out i never really understood the dangers if we had to do that then wouldn't ford come up with something better i never change my fuel filter on my f-150 v8

 

better gas does not clean out your filter the filter cleans out the gas, and high octane is cleaning out the injectors (sp?) you should change your filter about every 5 to 6 thousand miles to make sure your injectors dont get cloged
i do my mustang every year before racing so that is about every ten grand
but the L will get a new one every 5

 

It's a precautionary measure.

When your running a blown motor, you don't want to ever run the risk of leaning it out during a WOT run.

If you look at the filter you'll see that it is really small to begin with. And the $7.00 once a year price is'nt anything to cry in your milk about. You know?

It's such cheap insurance given that you can't readily see when you've purchased bad gas that I'd ask you "why not"?

WOT

 

Once you see what kind of damage clogged up fuel filter can create (and they do get clogged up, no matter which vehicle or octane or brand we are talking about) you will start changing them religiously once every oil change and you will slap yourself silly for not doing it before.

I agree that changing the fuel filter is a good preventative maintenance practice and is relatively simple to change, but every oil change is a bit much. Stay with quality gas and you should be able to get 6 months out of it easily.

 

as i understand it, octane has absolutely nothing to do with "clean." Not for the filter, not for the injector, nothing. Octane is an anti-knock additive that was developed in i believe the first world war for airplanes, its only function is to stop knock. The fuel filter takes out sediments and other particulates out of the gas thats in there, and keeps it away from the engine. You know those tanks at the gas station? Those tanks have tons of crud on the bottom of them, which is why its very advisable not to fill up if you see a tanker there filling up the station tank. Filling the station tank stirs up all those sediments and puts em right into your tank. Like Zoran said, leaning out on a blown motor will give you any number of problems, the most common im thinking is a thrown rod (at least in the Lightning engines). The way to preventing that is keeping fuel free and able to be injecter, and a good clean fuel filter is excellent for that, i recommend gettin the navigator that fits the L since its much larger and i think its just as cheap.]


Oh and btw, change the fuel filter on your v8, when you do turn it tilting toward the tank when you pull it off and see how black the gas is, if you havent done it before, i promise itll be black.

Oh yeah and on an L, i say every 6k, on a regular car that you dont drive hard, 12k is more than enough. Cmon guys its like 5 bucks.

 

I can show you fuel filter that took less than 4 months / 6K miles to start creating trouble (of course, it was on my truck ), and unfortunately I am not the only one with such experience (people say it can last as low as 5K miles). Comparing savings of doing it once every 6 months instead of once every oil change ($20 a year assuming 12K miles per year with 4 changes at $10 per filter) to how much it costs to fix what it can cause makes me feel once every oil change is not bit much. Instead I find it mandatory.

Less than 5k on a BRAND NEW 02 Lightning


I was lucky and only did this


Toast wasn't so lucky
His did this


BTW
I only used two Amoco NEW STATIONS with 93 octane

I now change it at every oil change,
did it a week ago, it was fine

 

Once you change it once and realize how simple it is, you should invest in a new filter every oil change. Takes a whole 5 mins to change it out. Use a small bowl that fits up there by the frame to catch the spilling fuel. Then use the black rubber or red rubber caps on the new filter to cap the older filter while you remove it.

Piece of cake. You can buy the small plastic tool used to detach the garter spring fuel line from autozone or step up to the metal fuel disconnect tool sold on all the tool trucks.

 

caught my attention! Anybody else using this? How much greater is filtering capacity? Part number? Thanks for any responses.

I did not use the L filter clamp although there is a pic somewhere that shows it in use with the bigger filter. I chose to fit two, long, stainless hose clamps togeather and then clamped it to the large, steel line that runs below the filter location. I also took a 3" piece of 5/8" heater hose; split it lengthwise, and placed it around the steel line to act as a buffer between the larger filter and the steel line.

No one really explained why lean is bad.
DETONATION!
There are plenty of threads on that topic.
We all like to pamper our L so just do it!

 

I could not agree more. I just changed mine for the first time last weekend, and it really is very easy to do.

My original was not too terribly clogged, never the less it is peice of mind to have the new one in.

 

...but some punctuation would help make your posts intelligible, too.

Not that I'm a punctuation ****, but I'm still recovering from the GiGi posts.

This is a period: . The first word of a sentence begins with a capital letter. A sentence is a complete thought.

There! I feel better now.

 

On subject of Navigator filters, does anyone know what is rated flow capacity of them vs L. What about rated fuel pressure they can both handle? Filtering capability in microns?
