Small Filter in Engine bay - whats it called?

Hey Guys,

Real stoopid question here but was inspecting under the hood and came across a small filter in the engine bay of my defender. It looks like its a fuel filter of some type but is quite small. Its in the front on the drivers side and is see through. I know the actual fuel filter is on the rear and I'm just about to change that but I was wondering what this other filter is and what its called? I have been looking for a replacemnet and cannot find one anywhere, it looks like its full of crud so I figure it needs to go?

:nopics:

A cheap and cheerfull universal inline fuel filter by the sounds of it but a photo would help.

does it look like this

Aye!! that's what I reccon it is mate, have to wait for the OP to come back on.

Not easy to fit one of them to a TD5 fuel system. If it is one it will be a bodge to try and sort another problem. It does sound like that is what it is though.

Cheers lads, yep thats her alright thing is full of crud, is it a hard job to fit? Looks like off and another on, but then I could be wrong, it has happened before

You're quite possibly looking at the EGR filter fitted to pre-02 Td5s, p/n ESR4323... if that's the case would rather invest in an EGR blanking kit.

Call out #16 on the following schematic:

Spot on there mate thats her! So can I just stick a new one in?

Not worth it IMHO!!

Rather get yourself an EGR bypass kit which will do your engine some good!
Dozens of them to choose from -- here's one example EGR Bypass Kits - Alive Tuning

You can use the lid of a baked bean tin to make an EGR blanking plate. They last about 3 or 4 years before burning through if you use them on the exhaust manifold. Much longer if you slide it between the corrugated pipe and the EGR cooler of EGR valve itself.

I dare say he doesn't have an EGR cooler as the EGR filter is only fitted to the EU2 engine (@ EU3 engine the atmospheric air intake is piped to the air filter box).

The EGR modulator acts like a transistor, switching the EGR valve from atmospheric pressure to vaccum as commanded by the ECU. Then every time the EGR closes the actuator sucks air from the outside thence the need for the filter in question.

Simply disconnecting the electrical plug on the modulator will shut it down ridding of the need to replace the filter.

That the EGR valve will still be there to create a restriction or possibly partially opening due to build up of bitumen around its seat is a different story...

Thanks for all the feed back, much appreciated! To be honest for the moment I would just like to replace the filter and look at blanking the EGR at another stage. Had a look on-line and the filter is only £3 or so. Can I just pop out the existing one and pop the new one in or is there a process? I have been looking around on-lline and cant find any info on putting a new one in.

Thanks again
