Brainless question about changing fuel filter... LOL

I am changing my fuel filter. This will most likely be one of the dumbest questions posted yet to date...

Do I have to have an empty fuel tank to change the filter?

I have never changed one on a foreign car before so I am just clueless here. :ybrick:

Thanks for the help

No. The fuel filter is location under the driver seat area. Should be easy to spot once you crawl under and start looking around under the drivers side.
 
Don't put your head or body right under the fuel filter! The line is pressurized and will spray the gas around. Make sure NO open flames around!

Use a TOYOTA fuel filter.
 
Thank You! I'll spray some WD-40 on it tonight and see if I can budge the fittings in the morning.

BTW Some Fun facts about WD-40:

WD40 stands for Water Displacement #40. The product began from a search for a rust preventative solvent and degreaser to protect missile parts. WD-40 was created in 1953 by three technicians at the San Diego Rocket Chemical Company. Its name comes from the project that was to find a “water displacement” compound. They were successful with the fortieth formulation, thus WD-40. The Corvair Company bought it in bulk to protect their atlas missile parts.

Ken East (one of the original founders) says there is nothing in WD-40 that would hurt you.

When you read the “shower door” part, try it. It’s the first thing that has ever cleaned that spotty shower door. If yours is plastic, it works just as well as glass. It’s a miracle! Then try it on your stove top... Voila! It’s now shinier than it’s ever been. You’ll be amazed.

Here are some of the uses:


1) Protects silver from tarnishing.

2) Removes road tar and grime from cars.

3) Cleans and lubricates guitar strings.

4) Gives floors that ‘just-waxed’ sheen without making it slippery.

5) Keeps flies off cows.

6) Restores and cleans chalkboards.

7) Removes lipstick stains.

8) Loosens stubborn zippers.

9) Untangles jewelry chains.

10) Removes stains from stainless steel sinks.

11) Removes dirt and grime from the barbecue grill.

12) Keeps ceramic and terra cotta garden pots from oxidizing.

13) Removes tomato stains from clothing.

14) Keeps glass shower doors free of water spots.

15) Camouflages scratches in ceramic and marble floors.

16) Keeps scissors working smoothly.

17) Lubricates noisy door hinges on vehicles and doors in homes.

18) It removes black scuff marks from the kitchen floor. Use WD-40 for those nasty tar and scuff marks on flooring. It doesn’t seem to harm the finish and you won’t have to scrub nearly as hard to get them off. Just remember to open some windows if you have a lot of marks.

19) Bug guts will eat away the finish on your car if not removed quickly. Use WD-40!

20) Gives a children’s play gym slide a shine for a super fast slide.

21) Lubricates gear shift and mower deck lever for ease of handling on riding mowers.

22) Rids kids rocking chairs and swings of squeaky noises.

23) Lubricates tracks in sticking home windows and makes them easier to open.

24) Spraying an umbrella stem makes it easier to open and close.

25) Restores and cleans padded leather dashboards in vehicles, as well as vinyl bumpers.

26) Restores and cleans roof racks on vehicles.

27) Lubricates and stops squeaks in electric fans.

28) Lubricates wheel sprockets on tricycles, wagons, and bicycles for easy handling.

29) Lubricates fan belts on washers and dryers and keeps them running smoothly.

30) Keeps rust from forming on saws and saw blades, and other tools.

31) Removes splattered grease on stove.

32) Keeps bathroom mirror from fogging.

33) Lubricates prosthetic limbs.

34) Keeps pigeons off the balcony. (They hate the smell).

35) Removes all traces of duct tape.

36) Folks even spray it on their arms, hands, and knees to relieve arthritis pain.

37) Florida’s favorite use is: “cleans and removes love bugs from grills and bumpers.”

38) The favorite use in the state of New York WD-40 protects the Statue of Liberty from the elements.

39) WD-40 attracts fish. Spray a LITTLE on live bait or lures and you will be catching the big one in no time. Also, it’s a lot cheaper than the chemical attractants that are made for just that purpose. Keep in mind though, using some chemical laced baits or lures for fishing are not allowed in some states.

40) Use it for fire ant bites. It takes the sting away immediately and stops the itch.

41) WD-40 is great for removing crayon from walls. Spray on the mark and wipe with a clean rag.

42) Also, if you’ve discovered that your teenage daughter has washed and dried a tube of lipstick with a load of laundry, saturate the lipstick spots with WD-40 and re-wash. Presto! Lipstick is gone!

43) If you sprayed WD-40 on the distributor cap, it would displace the moisture and allow the car to start.

P.S. The basic ingredient is FISH OIL.

P.P.S. I keep a can of WD-40 in my kitchen cabinet over the stove. It is good for oven burns or any other type of burn. It takes the burned feeling away and heals with NO scarring.
 
No, you don't have to drain the fuel tank but you should be prepared with a drain pan and safety glasses. Some fuel is going to drain from the lines and the filter itself.

Use a TOYOTA fuel filter.

I read somewhere that the Toyota filters were just rebranded Puralator?? Oh well, I bought one from Advanced Auto Parts. At almost 200K, I'm not sure I will own this one for more than a couple of years at most. Although my kid really wants it for his first ride, so who knows.

Edit: Just did the research and it is made by Denso. We'll see how it works. I can always change it out if it seems to cause any issues

how hard is it to change the fuel filter? i have a 2.7 4 CYL. is it also located under the driver's seat somewhere? is is as easy as popping the old one out and the new one in? i need to to this.
 
I'm not sure where the filter is on the 2.7l, if I remember right the filter is under the intake manifold on the driver side.The filter can be easy or a pain depending on what shape it is in. If the is rusted really bad then your going to want to soak it in PB or WD40 to help loosen the bolts. If it is rust free then there should be any problem removing the filter.

Would i need to relieve the pressure in the fuel line?

No, simply lose a nut in one of the fuel lines. Make sure to use right size and good quality tools for this job. My truck is from heavily salted area and I did not had trouble with rusted out bolts when removing the fuel filter.

Denso is Toyota OEM supplier. Toyota parts are not terribly expensive compared to non-OEM parts.

If you do 10 K a year and if you maintain the truck right, you will rebuild the engine in 2032!

Yes....you relieve the pressure by removing the filter. ;)


I've never had a 4runner fuel filter "spray" gas. Crack open the first flare nut, and just let the gas run out into a rag or pan. Once it's done, change the filter.
 
I gave the fittings a shot with the wrenches and its a no go. Ill grab some PB Blaster and give it a shot every night until I can move the fittings.

I suppose I'll do the gear and transfer case fluids too, since I know they are rusted wicked bad as well and Ill just PB Blast them over the next week until they all break loose.

Thanks for the info everyone!
 
Undo the gas cap. That will release pressure and reduce the amount of fuel that leaks out... Some people go as far as pulling the efi fuse and turning over the vehicle. Not necessary though

I have used this method but only because I'm not keen on making a huge mess. It gets all the fuel out of the lines before you open them up. The first time I did a filter change though, I didn't do anything more than crawl under the truck and wrench the filter off. It makes a bit of a mess if your not ready for it but do it the way you are comfortable with.
 
I tried changing mine on Monday. I bought the Toyota filter and I could not get it to no leak. It wasn't cross threaded, but something must have been wrong with the threads or something. I tried uninstalling and reinstalling it, cranking the engine over just to see gas sprayed all over the place. I ended up putting the old one back in and it works just fine. I'm going to return the part, but has anyone ever had an issue like this?
 
Finally had time to try and pull the old filter. After soaking the fittings in PB Blaster every night for the past 4 days. I gave it another shot and it broke loose without a problem. The only issue was that even though it only had about two gallons left in the tank. Gas leaked continually from the tank side line until I was finally able to completely pull the old filter and get the new one in place and threaded down tightly. I can't imagine what it would have been like with a full tank!

After getting the new filter installed, I thought I would see what shape the old filter was in. When I tipped it up to pore out the residual gas, the gas from both sides was cloudy with a grey/black color. I am quite sure that this was the original filter, and I can tell you that it is NOT a lifetime filter!!!!

I was shocked at how much black grime came out. I will for sure run a few bottles of injector cleaner through the tank after seeing that. Have not really driven it around to see if there is any better throttle response, but I highly doubt it.

Can't wait to see what the gear oil looks like later this week. I'm betting that it has not been changed in over 100K miles.

Yes a few years ago.. First make sure you have wrenches for flared fittings. Regular wrenches can round off the edges and then you are up the creek. IIRC you cal use a backing wrench (regular works here) on the filter to provide tension and then use the flared wrench to tighten hard. The backing wrench let me tighten it enough for no leaks. However mine was leaking slightly not spraying all over

Yea, I have a set of line wrenches. That was not the issue. I returned the filter to Toyota, got one from a parts store and did not have the same issue.
 
Filter has to be aligned properly, this could have been a fluke? Yes use line wrenches and be liberal w/ PB Blaster for a few days, you should ONLY use OEM filter, and crack the gas cap to relieve pressure. (This is for those preparing to do it)
