Copied from Tech Mec:-


Just had the Front wheels off (X250) to check and service a possible sticking Calliper. I noted what appears to be diesel on the lower surfaces and the source seems to be the filter housing. What exactly is the issue?, do the housings crack? or is it seal leakage. The leak SEEMS to be coming from the top of the locking ring. (hard to see in poor light).

I have read the Post by Teckno, but the link to the second part appears to have been removed?. (which I assume is the use of the "tool").

Any one have information.?

At the moment it is only a slight weep but in light of the fact that we are looking at going "down South" later this Month, I could do to get it sorted.

Usually the o ring. When replaced they need to be torqued up using the required tool. They usually fail if incorrectly torqued with a wrench. I now carry a spare complete assembly available from Coastal Motoromes via e bay. &£80 00 ish. Lot cheaper than a call out!

I thought the plastic bodies were prone to cracking if the incorrect tool was used to replace the cartridge?

When mine was replace, using the correct tool etc. All was well for over a thousand miles. Then it started a small weep. Close inspection revealed it was NOT from the filter o ring but from the seal of the fuel pipe into the housing.
I didn't bother trying to solve it & replaced the complete housing instead.

@PeteH The complete housing with filter can be sourced for around £80 on ebay, genuine part so no special tools required. Takes about 30 mins to an hour to swap it out. Dealer part is around £200, no brainer in my view! The only tricky bit, that I got scuffed fingers from was getting the blinking plug off of the top, other than that, it was easy.

Just buy the complete housing from eBay, a simple fit. They always leak after changing the filter. As the service intervals are 28,000 miles (!) it shouldn't need changing that often.

Hi, I had to replace mine about a month ago, I had to buy from the dealers ouch. it is so easy to do took about 5 mins in a pub car park. I am going to carry a spare from ebay from now on. The pipes clip off and on and the electric connectors do the same. The only tool required was a small screwdriver to prise off the clip holding the bottom electric connector. It really is a very simple job to do but also very annoying as it is very expensive for what it is.

No tools are required. The correct way to release the bottom connector is to depress the spring so

Contrary to popular belief they don't all leak. I serviced mine Feb 2014 and all is still good.
I do of course carry a spare, it would be foolish not to (y)

Well done Pete
Carry a spare (y)

In that regard, I am considering obtaining the "Fitting tool" and dismantling the old one to see just what the issue was. The leak appeared to be from where the ring and seal are at the top which may just have been a degraded sealing ring?. In which case a new filter element and a seal could be all that is needed?

The ones I have looked at have been under tightened at service.

Don't bother buying the tool, put the money towards the spare

You can borrow my tool if you want

My repaired one lasted a few months then quit on the m25

The failures seem to be getting the exact torque on the cap, too tight or too slack and it leaks through the O-ring. The replacement ones have marks around the rim that presumably were used in the factory to set the equipment.

My spare arrived today for our 2014 Peugeot slightly dearer at £94, but worth having no worries if old one leaks whilst we travell abroad.
I have also the proper tool and filter element when I take over the servicing after next March.

You might be right
I used a tourque wrench and the correct tooling
Still leaked months later
It's where it's dumps you that the problem .....

I take on board what is being suggested. My thoughts are 1) I am curious to know what failed (maybe that`s the "Engineer" in me). 2) IF I can "rescue" it, it would make a "get you home" spare at a lower cost than a full new one. I am unlikely to change another in the projected life between changes, (the vehicle has only done 34k in 10 almost years) in view of the miles we actually do, so carrying a "Spare" (New) would likely only benefit the next owner?.

Another though occurred. I understand that the earlier AND later ones have a different design, providing the though flow is the same, same Engine basically so it should be. Is there an Alternative which, with some adaption?, might be retrofitted and of a better quality? What do those in the "Trade" Think?

Agreed the repaired one will probably get you home but why waste the money on the tooling.

It's not about cost for it's about safety
The hard shoulder of the m25 is not safe place to be fiddling

Tens of thousands pounds on the Motorhome......£80 filter

On the hard shoulder of the M25?. If the RAC / Tyre fitters won`t change a blown Rear outer offside dual?. But they have to close the lane whilst we are escorted by VOSA to a layby on the Brighton Road!, (AND we get a "Mention" by "Sally Traffic"), then no way am I going to change a filter for even a NEW one!. So that situation is highly unlikely to arise!. I am thinking about making the exchange on a site to somewhere as a get me home!. IF it ever happens. As for the cost of "tooling" £15-80 is not a fortune.

Ok. So tool arrived. Used it dismantle Defective Filter out of curiosity, I find that the "O" ring type seal looks as if it has expanded?. There is a larger amount of clearance all round than I would expect?. (see uploaded pic`s). In my experience most seals are a tight(ish) fit, but this one has definitely got more clearance than I would expect.

So I ask the question, IS the clearance correct, OR would I be correct in speculating that the seal has been subjected to some distortion due to?. (Guessing now,) over-tightening?. OR possibly been affected by the action of Fuel?. I have somewhere seen it reported that BIO Diesel has been blamed for adverse effects on items not normally giving issues.? IF this where the case maybe my M-H has at sometime had BIO D in it, (Not in my ownership) but never the less in the past.

Any suggestions? (open season guys).

Pete
