[DIY] Change a fuel filter

[me2kimi]

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.

does this DIY will spill fuel?

mine did..

just checking

nicely done...i got 1 suggestion though...if you can include the price of the part will be beneficial of everyone else...

Only fuel in fuel rail spill a bit

That fuel filter cost me RM35. I think a bit expensive.

Actually can use any car fuel filter as long same size. Mine is using proton wira for 4age. Its cheaper

 

[me2kimi]

yer la bro. just notice that wira fuel filter almost same but cheaper. next time I'll find wira fuel filter also

 

[jy_1990]

how long is the service interval for a fuel filter?

 

[Jakk]

same question, how often should we change the fuel filter?

 

[me2kimi]

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.

shucks man...didn know ron95 is such bad petrol till so black eh...huhuhu...cheap quality petrol..

 

[mike77kl]

Nola bro, this black petrol was poured out from the old fuel filter of his car.

 

[lkeong88]

I saw japan halfcut open up fuel filter, the liquid inside is pink colour.

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.

 

[GearSpeedKelvo]

what is the part number of the OEM fuel filter of AE111?
What brand is the new one you purchased?

Thanks.

Hey guys,
What about the fuel filter underneath the seat for the Vios dugong ?

Anyone has experience doing that maybe can share ?
