I acquired a neglected 1999 F-150.
I’m going through it.
Replaced fuel filter today, BTW there is a special disconnect tool required, it’s $5 piece of plastic, buy it.

So I replace the filter, look at the old one and it has no brand. Just a number and the dreaded word…..China.

So I decided to autopsy it.

It appears to be nothing but cardboard.
It’s so funky I’m surprised this truck runs.

Replaced with Motorcraft filter.
Waiting for RTV gasket to dry on differential so won’t drive it until Tuesday.

215K miles on odometer.
I opened the diff expecting problems.
Oil looked good, no serious wear that I can see. Amazing.

Motorcraft oil filter and motorcraft fuel filter on my CVPI SAP

Used to use the K&N oil filter, Apparantly K&N changed and no longer makes the original size capacity oil filters the K&N 2010 and now its some smaller longer life pos when I went to walmart. Look really poverty made, wtf I said when I looked inside, looks incredibly cheap now, even tho I was the idiot who spent 10 bucks on an oil filter, but at least it didn't look like they are now. They def went to a cheap ass design now. Grabbed the motorcraft FL820 as it was original size and can't go wrong with motorcraft original

I have a friend who used to work in the Purolator factory years ago in Fayettnam. She said the only difference in filters were the amount of paper that went into the filter.

I don’t know what you’re getting at, they’re all cardboard inside.

Also, I’ll wait for you to pull the transmission pan and freak out when you find a mystery part rolling around in it.

Be sure to @ me.

Here's a surprise; even some aviation filters are paper.

Paper doesn't dissolve in petroleum like it does in water, it's not really a concern.

I take it you've never seen the inside of most oil filters?

What’d that differential oil smell like? You  never forget that smell.

Back in the late '70s, swapped the rear in my buddys '66 Chevelle, 10 bolt to 12 w/ 4.11s ( after going from the tired 327 to a 396).

Drained the lube into a pan, them poured it into a jug.
Burnt, smelled BAD.

Couple days later, was 4th of July.
Sitting in shop, goofing off drinking beer.
Somebody's dropped some firecrackers into the now empty burnt gear lube jug.

Exponentially increased the Stank Factor!

I  can STILL , 40+ years later!

Most GM guys probably like grape scented lube in their rear ends.

A few years after I had retired, a rookie cop moved in 2 doors down at the end of the culdesac where we lived in a suburb near Tulsa

As usual,  the new guys got the crap cars, he was issued an old Crown Vic with well over 100k miles

We were talking one afternoon while we were both mowing our lawns. He was complaining how shitty the acceleration was on the 4.6 liter in his patrol car.

I had already changed dozens if not hundreds of Fords little abomination they called a fuel filter (op is right, buy the damn donut tool) as I recall I even had a new filter in the garage

I crawled under his pos patrol car and popped the filter loose. He was freaking out because I had a little trouble getting one end disconnected. He was about to have a stroke because I was now doing unauthorized work on his city vehicle and he thought he would get fired (relax junior, I'll go back and fire YOUR fto if they give you grief

10 minutes later I was done, talked the boy down out of the tree, and suddenly his old pos patrol car had some get up and go! (No shit, son?)

Ps: The boy made sergeant last year. My how time flies watching kids grow up

I have a good "Mystery Part" story, I was changing the rear main oil seal on my 2001 Jeep Cherokee XJ to prevent the beast from "Marking its Spot" in my driveway.
When I'm taking the oil pan down I hear something banging around, I look & there is a hydraulic lifter laying in the oil pan, I'm like Fuck, I'm screwed! I reach up & check for a missing lifter & there is nothing missing; apparently some top notch  UAW Chrysler worker must have dropped it in the pan when assembling the 4.0 where it remained for 8 years before I found it. Can't beat UAW quality!!

One of the reasons I have four fuel filters on my F-350 PSD.

I’m sure that fuel filter is/was crap.   But a lot of that visible ‘contamination’ is from you cutting it in half.
When doing autopsies on canister filters, cut at one extreme end or the other.

No need to cut through the element.  Just the circumference of the canister.
And, using high speed and/or abrasive cutting tools will put gritty metallic crap inside your filter.
Take that into consideration.

There are purpose-built filter cutters.
I’ll BRB... gonna post a pic

I go through 4-5 of those a year on dads f250.

Lots of glacial silt and water/moisture in the fuel.

I even change the filter socks in the fuel tank every year.


Wish the damn taco had outside fuel filters.

can you pull the sock and install an inline filter?

Looks like a fuel filter, last motorcraft one I had rusted out and was pissing a stream out.

Motorcraft one is probably made in china too.   Auto parts in general are shit.

A 99 F150 by me was in the junkyard by 2005 rusted in half

That looks clean for a 99
