Fuel filter

I changed mine at about 175K. It was clean when I cut it open, and noticed absolutely no change in fuel economy, performance, whatever, after changing.

My truck has been a south/central US resident its whole life (Tejas, Bama, Oklahoma), and I'm not sure what kinds of fuel the previous owners were using but I put standard Regular in it for the 40K I've driven it.

I ended up using a wrench made for flare nuts -- it has the tips extended slightly inward to provide better grip.

Found a cheap one at a local hardware store.
 
I've been running with the new fuel filter for around 1,000 miles and I'm getting a hard start in the mornings and after it's been parked for an hour. When started after that it starts fine and quick. It runs great and all, maybe it's the fuel pump. Any ideas?
 
I wanted to add an update to my previous post. After running errands all day the truck is starting quicker(the reason I changed it in the first place) I don't notice anymore power or anything but the fuel that came out of the old filter was nasty and brown. So I guess in the end it was worth it.
 
i've been recently noticing a strong smell of gas outside of my 4 cyl. and i have a lot of pressure/suction in the gas tank when i remove the cap...

did replacing the fuel filter take care of either of those issues?
 
Just changed mine today.

After 1.5 days of soaking with PB Blaster, it came off VERY easy. So stoked about that. Keep in mind we use a lot of salt on our roads combined with winter snow, and summer mud packing in there. Rust was minimal on the flare nut so my hopes were high and was surprised when I took the high pressure line off with a slight wack of the flare wrench. Intake was the same.

I sprayed the nuts with Fluid Film to hopefully help with corosion for future changes.

Vehicle has 237,000 KM. I haven't had time to test it other then some start/stops in the garage. More tomorrow when I get back from wheeling.

I think I remember that someone used a Wix fuel filter here, or maybe it was on YT, and its diameter was larger than OEM, so fitting it in the bracket was a PITA. But it may have been a Bosch.

Going with OEM takes any guesswork out of the equation.

But hey, try the Wix, and report back on how well it is doing for ya down the road.

I put a WIX in mine with no issues at all, that having been said I do wish I had gone OEM for the piece of mind.
My local dealer wanted 50 dollars for one!!! I HATE Berkeley TOYOTA!!
I got it at Orielly's for around 15 I think
 
Ok, so to confuse matters slightly. I just got off the phone with the parts department at my local dealership. When I asked for the fuel filter he asked "which one" "by the fuel injection, or in the rear?" I assumed the rear and he said it was $10, he said that the black, can shaped one that goes by the fuel injection was $37

Anyone know what he's talking about?
 
I've put several fuel filters on my 99 over the years. I always get them at Autozone or Checker, hell, I think I've even bought them at Walmart a time or two and have never had a problem with them leaking. It is one of the easiest and cheapest fixes to ensure clean fuel flow. With all the crap they add to fuel and the junk that gets moved around when the trucks deliver gas to the stations, it makes sense to change them.
 
I know this thread has been dead for a while....but can you just use a regular set of open end wrenches for this or should I specifically find a flare wrench?

You could make it work with normal open-end wrenches, but it is just a lot more of a PITA that way and there is a higher chance of buggering up the flare nuts.
 
I sprayed it down pretty good last night with some on blaster, gonna hit it again this morning and then tackle it in a few hours.... Hope it doesn't give me too much trouble
 
Ok guys I've got a question for you.
This past weekend at 6 am I was on a road trip.
I've got a lifted truck tube bumper (absolutely no aerodynamics). Going 80 up a long 2-3 miles hill floored and over drive off turning about 4k rpm the whole way.

I have taken this hill many many times before and never a problem.

When I was almost to the top I could feet a hiccup in the motor. Like a slight miss or one cyl was quitting out. I'm talking super small. Then it would pick back up for 2 seconds then do it again.

In the past I could keep 80mph up the hill the entire time but this time I dramatically slowed down towards the top to about 65 and would not go any faster.

After that hill it ran like normal and 400 miles later still the same like normal.

So my thoughts were the fuel filter was not flowing efficiently enough and lost all the pressure in the lines from high rpms.

What are your thoughts? Should the pump be able to sustain these type of demands. Are the injectors large enough?
Am I correct that it's most likely the fuel filter?
 
Your pump and injectors should be fine. Yes that is high RPM but nothing to worry about, when was the last time you did plugs?
