Hi all, just wanna share how to replace a fuel filter on AE111 4AGE engine. I think AE101, AE92 and 4AFE engine would be the same.

p/s: The pictures I took is reverse order (installation process to remove process). But I tried to explain it in removing order.


1-Remove fuel hose at bottom of the fuel filter. 14mm nut


2-Remove fuel filter holder at the side of the body. 10mm nut


3-Remove fuel hose at top of the filter. 17mm nut



4-As we can see here yellow Ron95 petrol has turn to black and maybe clogged injector too.


5-New fuel filter on the left.


6-New filter on the right.

After change to new fuel filter, my butt can feel my car more responsive.

I dont know how frequent to change the fuelfilter. But whenever I felt the engine is lack of power and the fuel filter already used for a year maybe, then I'll check the fuel filter.

I just change out an old fuel filter for my 1991 Saga Auto 12V Carb to a new one i bought.
I think the filter is as old as the car, looks dirty. Maybe the previous owner never change it.
So after change the fuel filter, i felt no different, damn!

IMHO...fuel filter does nothing to increase the performance...just the fueling efficiency dropped...like the original post said...if the fuel injectors is clogged up ...then you can feel the sluggishness...

but since you on carbs...better do both...change the fuel filter and clean the carbs...then might feel some different...with new fuel filters...the carb cleaning intervals also can be extended...

Does changing a fuel filter for a carb engine makes the car eat more petrol or less?
Now i felt like ever since i change the fuel filter, my FC is higher than b4 and there
is no noticeable performance increase. Doh!

I tot a clean fuel filter could help save fuel coz each time i read the top 10 tips to save
fuel, sure it will mention about fuel filter. Maybe it just apply for EFI cars and not carb.

And now new finding says that a new air filter wont help save fuel for EFI cars.
As for carb, that still applies. Maybe the mixture for carb already fix, so if less air
from a dirty air filter, u run rich. As for ECU cars, it will calculate and rebalance
the A/F mixture, like less air due to restriction from dirty air filter, then less fuel
will put into the mix, u get performance drop only maybe and wont run rich
but if some sensors is spoilt, ECU could get fool too to run richer or leaner.

Just my thinking, i could be wrong.

I get no benefit after i change my fuel filter. Car still starts up the same, performance same,
only FC a bit worst then b4. And if i know i should'nt have fill the aircond gas also coz my
aircond is less cool now, big diff, and the compressor making weird noise. All due to one day,
i was pandai2 go look at the tiny window of the dryer unit and i notice it was bubbling.
I remember bubbling is no gd, it means not enuff gas. So i took car to shop and the
fellow let go the old gas which i think is r12 and he refill it with r134 (written on invoice)
and he ask me go look at the window again, see no more bubbling, i said ya ok perfect thanks.
Now very regret, aircond 3x less cold than b4 was chilling.

FYI: My car is a 1991 Saga AB Auto 1.5 Carb 12V Magma
Avg FC: 12km/L

Weird, highway FC is no better then city. Maybe due to the fact that at highway i go faster
and faster means too much wind resistance and drag from the poor aerodynamic design plus
the 3 speed engine is screaming already at 120km/h and my engine needs 3500rpm to get to
100km/h, very bad!

My experience observing mechanic changing oil filter on my Proton Gen 2, fuel will come out from the fuel line. But very little.

Bro me2kimi, have you tried to open the fuel filter and look at the element? You can see dirt that coming from your fuel tank collected here.

Fuel filter also need to change, probably 30 to 40k km. Can check also, remove the filter shake and pour out the fuel onto a white piece of paper. If plenty of dirt comes out, please change......lol

The filter is called a fuel strainer also right ?
It's not that difficult to change right ?
Sorry bro many questions cause I saw a video on the Subaru fuel filter oh my goodness, this guy disassemble the fuel pump to fuel filter damn long son.
And also
Wanna clarify the previous vios before dugong same fuel pump assembly withvios dugong ?

Lol 40k km. Gone lar my Vios,
The manual say 80kkm change filter.
I need to learn this asap so I can change it. Putting back the fuel pump and filter assembly don't need to use the gasket sealant right ?

If filter together with pump, then sorry case, very expensive to change. So far for my fuel injected cars one located at undercarriage between driver and rear passenger seat. My other car filter is in engine compartment.
My VR, I have seen mechanic take out fuel pump before, it has an additional strainer before going in to the pump and actual filter is in engine compartment before going to the injectors.
I changed mine once at 40k km and was pretty dirty already. I shake and pour out on white piece of paper, plenty dirt came out.....lol
Whether can last 80k km depends how clean the fuel you pump into your tank. Usually if can see the truck delver fuel to the station, I won't pump because when when they pump into their underground tank, may churn the dirt up from the tank floor.....lol

Wah, your VR got two fuel filter lol, double the protection.

Crap, the spare part shop seller at new era industries in old Klang road say they dont sell the fuel strainer only, he say sell pump and strainer together. That one quite expensive, I'm trying to find for the strainer only so I can protect the pump and injectors etc.

The strainer is an open filter. Quite coarse looking plastic netting. I think more to block big particles jamming the pump. The fine ones that passes through gets filtered but the filter in the engine compartment.....

I believe all in-tank fuel pump has a filter at the pump itself but this one will only filter out coarse particle.
The additional filter will strain smaller particle.This filter is normally outside the tank which is very easy to replace,just remove and replace.be very careful not to damaged the hose plastic lock thing.
Being showered with petrol can be very refreshing if u dont position yourself out of the way when removing the hose.

Some car is using in tank filter like the Kenari. On the Kenari is even worse, as mechanic said need to drop the tank.

I followed the fuel rail from my engine compartment all the way to the tank but I couldn't find the fuel filter :( although my owners manual says change fuel filter (including in tank). I'm assuming there is two that's why it's stated in the manual but so far I looked here and there in engine bay don't have.

any round cylinder black metal thing bolted at the firewall in the engine compartment?
Backtrace the fuel hose from the fuel rail to search for the filter in the engine compartment.

From my experience, OEM Toyota / Honda / Nissan parts are very pricy. U can get replacement from reputable brand such as Autonas for less.

Thanks guys, appreciate it, I'm gonna search around some more. Gonna check out autonas as well

I've checked the firewall that side started tracing from the fuel rail alll the way to the underbody then to the fuel tank.
Don't have anything that is cylindrical shape or fuel filter like how I've seen online.

I think dugong only have intank fuel filter..

I'm gonna put some hopefully useful information over here for intank fuel filter replacement just in case some one like me trying to search up on DIY stuff.


There's a clip underneath the sit that can be taken out but have to be careful not to brake it
