Fuel filter

[Yeobh]

In many develioped countries skill labour charges are as high as medical doctors thie fees are charged by per hour. On top of that they do not do fire-fighting on-call basis, you have to place booking maybe weeks ahead.People in such places just have no choice but to DIY even to the extend of reading directly from the "How to fix.... " book for the not-so-handy.

Comparing the value of the cars in developed countries vis vis ours it is still cheap to service and repair cars in Singapore.

but i suppose replacing it is not "diy-able" ?

 

Have you checked to see if your fuel filter is at the rear (petrol tank) or inside the engine bonnet?

 

The past 2 cars I have, had fuel filters in the engine bonnet. Changing it was quite easy. Just that you need to get something to crimp the pipes so that it won't be too messy.

 

I didn't use any crimpers when I was changing them. Just need to do it fast. The line that comes from the engine don't usually have high pressure, unlike the line that comes from the tank. (if I remembered this correctly) But anyway, some petrol will surely leak onto the floor. If you do it carefully, there shouldn't be a outbreak of fire. The risks I feel is about the same as topping up petrol yourself. If you are not smoking and doing it in a cool area, it should be ok.

 

On a standard car, the fuel filter is usually 1 pipe in, another out. On some high end cars, with built in accumumlator, there can be 4 pipes going in/out. (but usually this is not the case for most)

 

If your fuel filter is metal, then it's quite expensive compared to the plastic one. But anyway, you don't change them often. maybe 40,000 or 60,000km? Anyway, fuel filters don't usually cause problems.

hee......i have never seen how it looks....that's why not even sure if its in front or behind...

 

i am generally interested in maintaining cars myself, hence wanted to know more like when its due for fuel filter change and how to diy

[Kianbeng]

maybe you should call up those parts shops and ask if it's plastic or metal. My mazda's fuel filter seems to be at the rear.

 

For me, I'll go msia to get it replaced. Coz I've got no jacks. If I crawl below, and if the petrol leaks, damm, I'll be soaked in petrol! Bad idea.

My mechanic is in JB leh. about 30 mins drive from customs. I've changed it when it was 40,000km. now car is at almost 70,000. About 10,000 or 20,000km more then I'll get it done again....

 

Are you sure you want to follow me to Taman Universiti? I think there might be some other MCF bros here who have nearer lobangs. I go there because my wife's parents staying there.

I'ld DIY it myself if mine's in the engine bonnet. Unfortunately, it's not. So like I mentioned earlier, I wouldn't want to get soaked in petrol....

 

[Acemundo]

hee.....looks like i got the wrong message.

See attachment for fuel filter

[Kianbeng]

Is that for his car?

 

Where's this area? definitely not in the bonnet or undercarriage. looks like somewhere behind the back seat.

 

Mine's undercarriage.....quite certain.....

 

[Acemundo]

thanks for the pic.......hmm will try to find out which part of the car it is in

[Yeobh]

No this I believe is a US Ford ( the fuel filter is Motorcraft- OEM to Ford ), I use this photo for sales purpose.

Location just below the boot, look at the right side of the photo you can see the shock absorber mounting end.

Notice the fuel filter is locked to the inlet and outlet fuel line with special locking device. For Carb engine, the fuel inlet and outlet lines are normal connected with simple circlip or worm gear clip because the the fuel pressure is very low about few psi. Fuel injection engine the fuel line header pressure is high about 80 to 100 psi so if the connection to the fuel filter both inlet and outlet are not securely locked into position , any seepage of fuel vapour will be the end of the car

hm....this locking device really looks different. In a E200 W210 that I just sent it for replacement of the fuel filter last week, they also use a clip.....(don't know what type), but it seems to be very convenient/easy to take out or put it back.....but I was told they can hold higher pressure (like what you mentioned) as compared to the traditional ring clips where we use it to tighten pipes.

US and European car makers differ very much in designing car systems.

Bro ... is our fuel filter not under the back seat, attached directly to the fuel pump ??

[Kianbeng]

is it accessible under the back seat?

 

hmm...can't remember.....I thought it's under carriage.....unless i got mixed up with the E200.....I also forgot liao.

 

if it's under the back seat, then it'll be easy for me to change it....

Yes ... take out the back seat and just unscrew 5 screws and voila .... take out the whole damn pump and the filter is attached there. But be careful if you changing yourself ... the filter can break easily if you try to force it into the pump.

 

ps : You are accessing into the fuel tank itself ... so dun smoke while doing this
