Hi, just thought I would show what the internals of my diesel fuel filter looked like after 30,000 kms of filtering fuel (approx 1500 litres of diesel) this being the 60,000 km home service. It's visibly dirtier on the outside than the inside with a fine dark product, but certainly no sludge or excessive filth. No sign grit or rust and not one drop of water found. The new fuel filter was sourced from Burson Autopart in Ferntree Gully for AU$30.03, ex stock. Air and oil filter was ex stock too, oil filter AU$16.37, air filter AU$27.16. In my opinion the fuel filter it would be good for another 30,000 kms but for AU$30 why other risking it.
Hope it's of interest, Cheers. Instroe.

Instroe,good post,some time ago I did the same thing,I scrificed a new filter as well,when you consider when looking at the old and the new and the difference,even the one you have posted here,even though to the eye it does not look that dirty,in engine and injector senses,it would be considered filthy.
Like you also pointed out for the small price of the filters,why would you risk running them longer,thanks again
-
i usually keep the fuel in them, then shake them like hell and back flush the fuel into a white ceramic bowl and inspect it for dirt!
mine was pretty good, ive had them where the fuel coming out is black!
-
I believe Diesel Bug, is black. :(

I just checked the invoice for when I got the fuel filter changed by Hyundai (at 58,130 ks). $182.15. !!!
Labour $47.25, parts $118.36, tax $16.56.
How difficult is it to change the fuel filter? The workshop manager once said to me that it's all under high pressure and best not to do it myself.
-
Eureka,he's full of abbot,yes it is under pressure,but as you have tmo bleed the system anyhow,put your fuel pump fuse,start the car till it stalls, then if you have the correct spammers and know which things to disconnect.when you have done it a couple of times it is a twenty minute job,they seen you coming from a few kilometres away. I really hate the dishonest and rip off mentality of Hyundai servicing
-
Don't know why the fifth word changed from what I typed,me thinks someone has a funny filter set :rofl:
-
The labour cost isn't so bad, it's the rip off cost of the actual filter that I balk about paying. :fum:
You can buy genuine filters on fleabay for a third of the cost Hyundai slug you...

Sounds about right, anyhow.... :snigger:
-
Yes I typed full of shite,it came up as full of abbot,someone has a sense of humor
-
:rofl: fooled the filter that time,I'll be getting told off soon :evil:
-
There's a pictorial "how to" here somewhere, just gotta find it. :undecided:
Have a read of this,

Thanks to you and to instroe. It's looks like a very comprehensive guide. Should be do-able for me. I won't be doing it real soon but I will let you know if/when I do it.
-
Yes, a good report from Instroe. :hatoff:
Get a quote from Hy, then let us know how much you saved. :goodjob2:

Thats why they don't get the servicing for mine. My 90k service was $540 (inc auto service) theirs was over 1k, and they wouldn't be using Mobil one oil, and they just change the auto fluid, I got mine completly flushed.
And yet for the wife's car, its fixed price at $289 for the whole service (up to 45k from memory). I don't know why they didn't just make it for every car, not just cars bought after whatever date it was. Imagine having two people at the counter, one with a car that is under the deal one that isnt. Same service, one pays $289, the other pays nearly double.
-
I get mine changed a 30k but a m8 did 180k sold his ford focus diesel never changed filter car ran good got a new focus
I would not risk it, the job is easy I watch my mechanic do it he charged same for service every time did not matter if filter changed or not, I supplied filter ( genuine from hy spares ) but this time hy will do it so will see
-
Today I was quoted $135 (including tax) for an FD i30 CRDi fuel filter, genuine Hyundai part.
-
Quick search on Ebay reveals $59.50 delivered....
Which is expensive from my recollection, I keep an eye out once I have done the minor service.
If you do a search in the ebay section you might get an idea of price...

If you don't want to bother with Ebay, try your local Kia parts department .. The Kia Soul uses the same filter (same part # too from memory) last time I checked was much cheaper.. :happydance:

Does renewing the diesel filter do much for fuel efficiency? Even though the service book is all ticked and filled out, I'm actually not sure if it's been replaced. Car has done 107,000km.
I mean, the service book claims the auto trans was done at 90k, but it wasn't. I did a complete flush myself at 105k upon checking the fluids. Wasn't very good at all!
-
If in doubt, replace the filter, but who is doing your servicing. If you've been charged for a filter and the time to replace it, then you're clearly being ripped off. If it was done before you purchased it, I would have it replaced just to be certain. The diesel filter most likely wont affect your fuel efficiency. If it is dirty, fuel flow can be affected which would cause low power or cut out of the engine entirely.

I would not have thought so.
Was meant to have been done before I got the car. Can't really verify any evidence it has been done, so I think I'll do it myself. It's definitely not hard.
I do the servicing myself, keeping all receipts and records, and signing the book where required.

Thanks, been looking at that site for a while. :) Very handy.
-
just thought i'd point out, a set of new injectors cost around $5,000, that's why i change fuel filter @ 30,000k & know others with other brands of diesel's that change @ 20,000k but there filters only cost $20, i know Hyundai charge like a wounded bull for there filters, but you can buy heaps for $5,000. so i'll play it safe till warranty is out.

Fuel filters a lot cheaper from Ebay John!

Google have stuffed up apparently, however member Instroe has kindly provided the file for me, so here is a link to the package.

:thanx: Instroe. :goodjob2: :goodjob:

Fantastic, thanks Phil. And of course a big thank you to instroe for making the guide :goodjob2:
-
Just changed the filter, took a little longer than I was hoping due to spending 30 mins looking for my deep 12mm socket and then dropping said 12mm socket into the engine bay :head_butt: so had to take the bottom plastic tray off.
Access really is tighter than a ducks arse, but following the guide is easy - cheers, instroe.
My car had cut out whilst driving (twice) one day last week (both within a mile), and done it again a couple of days ago. No faults logged so garage suggested filter. I bought the Genuine Hyundai filter for £25.
Hopefully it was indeed the filter at fault, the diesel from the used filter certainly had a bit of debris in it.
-
Can you identify the debris at all. Normally there should be no hint of contaminant at all. If it's black organic stuff, you may need some Diesel bug treatment, or your problem mayl simply return.
-
Organic? How would you tell? Got rid now, but it looked like tiny bits of black grit/dust.
It all settled to the bottom of container, wasn't suspended or anything.
-
Organic, as in soft and breakable, or inorganic is it metallic or gritty. Whatever it is, it shouldn't be there. This is a potentially serious situation. The common rail Diesel has a specialized fuel pump that feeds the injectors. Pressures in the common rail can reach 23,000 yes that's right, 23,000 psi when injecting into cylinders. To do that, the pump operates with extremely fine tolerances between moving parts. Any "grit" getting into the pump or injectors will certainly cause damage. That filter is the last line of defence for the pump and injectors. Did the material look like small rust flakes at all.
-
Hmmn.. Wish I hadn't just chucked it now!
Could have been really small bits of rust I suppose?
I just assumed the filter was doing its job and thought no more about it.
Should I maybe look at changing again after a thousand miles or so and pay more attention?
-
When there is contamination in the fuel tank, a flush out is required. From Hyundai, this costs about $300. Not cheap but necessary if you get Diesel bug. However, there is an inspection hole for the fuel tank located under the rear seat. If it were mine, I would drive the car till the tank was nearly empty, the open the tank and see if you can use a good torch, (don't drop it) and check out what's in there.
You may not have any Diesel bug, but if water has collected at the bottom of the tank, it will eventually start to rust. If you're not confident to go messing in this area, perhaps a local mechanic can do it for you. This is not something I've done personally, so can't advise on the difficulty, although, if you can change the filter I think you could do this too.
-
Thanks. I'll have a look under the seat . then decide if I'll take it further myself

Here's a print out of fuel tank removal, which you don't need to do.

That's extremely high pressure Phil , are they still using springs in the common rail diesel injectors? ( i've never looked, but have looked at petrol injectors.
if your going to look into your tank via under the seat id give the floor a good vacuum & clean out first.
