Fuel Filter 04 Ch lancer

Hi. I was hoping I could get some info from anyone regarding the fuel filter of my Lancer.
I have done 2 services on it (plugs, oil, air filter) and both times I have been told that the fuel filter doesn't need to be replaced as it's in the tank.
It's got 145,000 ks on it and is starting to splutter at times when going around corners or when iv'e slowed down at the lights before they turn green.
I was told by a parts guy that a injector cleaning solution (wynns etc) would fix the problem but it hasn't.
Just wondering if I can replace the filter or is there another solution.
Did the last service at around 143,000 ks. It's an 04 CH.
Any info would be great.
Thanks. Grungle72
 
:lol: Sounds like a load of crap...it still needs replacing. If it's in the tank then try lifting the rear seat lower cushion up and there'll probably be an access cover for the pump and filter in the tank...
 
lol what ryan said, it still needs replacing, what the guy meant was, "Its in the tank, I cant be fkd replacing it, it will be fine as is"
 
I have only ever replaced 1 ch lancer fuel filter, this was because it had run on e10 for 280,000k's. I had to replace the entire assembly with a new pump as well. The car was towed in not running, generally we dont replace them because the plastic housing will break 99.9% of the time. But if you want to replace it that's not a bad thing, if i owned a ch a would replace it every 105,000k's like mits want. Beware its a expensive filter tho, send me a pm if you are local to the newcastle area and i might be able to get you one at a better price.
 
Thanks all for your help.
Thought it weird that it didn't need replacing. Can't think of any manufacturer with a lifetime fuel filter.
Chaser, i live south of wollongong and have a few good contacts for parts and stuff but thanks anyway.
Will check the back seat access and see what happens.
Again, Thanks for the info and will update the out come.
Cheers. Grungle72
 
Back again.
$177 later and around 20 mins work, the new filter is in and the spluterring has gone.
Also put an injector cleaning solution in to get rid of any other crap in system.
Filter was $177 and was quoted $200 to put the thing in.
How do they justify $200 for an apprentice (guessing) to work on the car for 20 minutes.
The fuel consumption is also better.
Cheers. Grungle 72
 
Good to hear it solved your issues!

Was it just a filter element or a whole assembly that you had to replace??
 
Yeah $177 sounds about right coming from Mitsubishi. These fuel filters are inside the fuel tank and only need replacing around 105000ks.
 
Don't get the Wesfil Coopers aftermarket fuel filter because they have a hole for the return hose line which is absent on the CH. It'll only fit Evos. If you do find another brand, make sure it has no return hose lines and only one main high pressure hose line.

This is what I mean:

Okay so I had a suspicion my fuel filter was a bit blocked... And as a result the fuel pump has now packed in.

On my pump assembly, I have the return hose :? you sure that's not standard on CH's?

EDIT: Upon further research, I have found that the 4g94 CH's have the return hose, whereas 4g69 do not. Since I'm replacing my filter and pump assembly, I will post a proper DIY with step-by-step pictures once the parts arrive.
 
Just fitted a CooperWestfil WCF208 (interchange with Z909) & now engine won't Start. Checked pump is OK, seems like air lock? or whatever,? Yes, does have 2 pipes (1xreturn, 1xsupply).
Any ideas please.....
 
Run me through it a little better..

Won’t start? Does this mean cranking but no start or is it no crank, no start?

You checked the pump? What does this mean?

With the two lines, are they on and on the correct way?

Sorry to be so brief...... I've fitted an (after-market) Cooper Westfil fuel filter (it's rather like a plastic toilet roll holder?) identical by looks to the factory Delphi unit. Upon successful replacement, the car CRANKS but no start.
With the cover off, trying to start no pump noise (but I'm 1/2 deaf?) BUT when disconnecting hoses (no supply from pressure hose or the return hose?) meaning there's no fuel going anywhere??
So after 2 careful removals to check everything was correct (yes checked the pumping working with 12V dc across the pump terminals directly...all good).
Re-installation and again NO operation! Solution: re-assemble original pump & all works well. Strange?

PS: Whilst a dealer would replace (with OEM unit), being in-tank this filter gets forgotten? I just cleaned the pump strainer, shame you can't buy separately and returned the 'new' filter for a refund. Is there something that other Lancer CH owners have learnt?
 
Sounds very odd! I replaced mine (04 ch) with a ryco unit which from memory included the hanger or part of the assembly. I had to transfer the pump onto the new one.

It was a bit more expensive but I had no issues. I also upgraded my pump to suit my turbo setup at the same time.

The CH won’t active the fuel pump until the ecu registers the engine is turning. This is why CH’s will crank one or two times more than you’d expect before starting, even when warm.

Perhaps this affected your testing of the pump? Maybe a bad connection to the pump or even possibly a bad filter that wouldnt allow fuel through.

I don’t trust my ears to tell me if a pump works either, dont worry! Haha

Yes, very strange. Could be a faulty filter? I was apprehensive about the 'brand' but the old unit (OEM) is staying in. In fact, can't see how that 'plastic toilet roll holder' actually filters anything? Having a new pump fitted gives you a clean strainer (the only thing that filters?)...
Thks for the ECU/Pump whirling tip.

Not sure if this makes sense, but there is a filter in the plastic housing. I found this image on an evo forum.

Personally never had an issue with Wesfil but things happen. Main thing is you got your car going again! You can revist the fuel filter whenever and probably at twice the speed now.

The fuel sock on the filter is to protect the pump, the filter we change is to protect the engine. Usually just clean the sock with brake cleaner or whatever. You get a new sock with a new pump.
