Have to say they just look like bits of foam stuffed in a tube. Can't say I'd be happy relying on them.

Q for Doug. do you have the link for the £5 filter you installed. I'm now curious as to why it did not appear to work?

Having a look around the web it would appear that some filters do state the filtration level in microns. If we could find out what the filtration spec is for the Mitsy micro filters, then find a matching bullet style filter to insert in line, then job should be a good un. Don’t know how you would get that sort of info from Misty though?

Yeah, it definitely needs an inline filter housing that comes apart and takes these micro filters.

Get scanning the web guys. Very Happy

Found some on alibaba.com to fit Lucas and Bosch fuel injectors. May be of use?

The one I've got 170532144732 search on eBay. But I'm thinking about trying a different one. I have a phone pic I can send of where mine is fitted.

Having had a look into this it would appear to me that the Mitsubishi Micro filter is probably a 10 micron filter. So a search for 10 micron filters brings up american after market filters for performance engines or aeroplane applications. These can be had from $60 each however, these fine filters have differing flow rates so if you don't get the right flow rate for the vehicle you could have the engine light on again!

Its a case of obtaining the flow rate of the Mitsubishi micro filters or "suck it and see" with a 10 micron aftermarket fuel filter with a high flow rate.

I'm thinking it wouldn't be impossible to find a pipe coupling that you might be able to install one of Mitsi's finest in for ease of changing.

Y'know, maybe even one of those ebay things I posted the link to you might be able to wedge one of them in the body rather than the cigarette filter they have in there. (I doubt a cigarette filter would work as I'm sure the petrol would probably melt it.)

Fitted the new micro filter to the feed line to the pump this morning, a bit fiddly but didn't take very long (many thanks to Doug Hope for the job description, spot on).

Pleased to report that i can now give her the beans without the engine management light coming on! Hooray!

Note: I was surprised when i removed the old micro filter as i expected to find lunge in it but i didn't. I am wondering if they just deteriorate over time in UK fuels?

No problem, hopefully save you some cash. My old ones usually look a bit blacker than the new.

Been there done that lol. I have a really sad fuel fill up routine. But no problems since jan/feb.

If anybody out there still reads this?......how do you get the micro filter out of the fuel pump.
I have a 2001 3.5 V6 GDI. SWB.
I can't get my micro filter out at all. I screwed a wood screw into filter and tried pulling it out but it will not budge!!
Any ideas please or pictures.
Thanks

That was precisely how I did it. You need a suitably sized screw that will get a good grip but not penetrate far into the pump. If you've got this far then presumably you can compare screw sizes against the replacement filter? It took me two attempts because first time I was too diffident and the screw didn't bite enough. I also fitted an in-line fuel filter on the nearside bulkhead.

The other issue is applying steady pulling pressure rather than jerking it to avoid it braking in-situ. A large block of wood suitably placed to act as a fulcrum to lever the screw with a a pair of pliers or grips was my method.

Here's photos from when I did the micro-filter replacement. There's one showing the new and old filters with the screw still in place. Ignore the fuel-pump photos - I didn't replace that.
