Just changed my fuel filter today, damn these MB clamps are hard to take off~

Yes, replace these clamps with screw driver ones from Autozone~ and make sure you wear latex gloves and safety goggles.

Will any brand do? Surely, Bosch will last longer, I suppose. Just curious before I make the decision to just give into the dealership's OEM 115 dollar part instead of the 59.99 dollar part at autozone.

Lane, the OEM filter is a MAHLE-KNECHT, and is available at RM European for $40. The Bosch from Autozone would work perfectly fine too.

+1 Filters are not all equal but either Mahle or Bosch would be absolutely fine. Please don't buy junk filters.

hey guys I am about to change my fuel filter and i am wondering if there is a fuel pressure relief valve on the m112 engine and where it's at or if opening the gas cap will do the job. thanks

Here's a great write up with pics. I just did it on my car, hardest is to get the clamps off. Infact they kinda pop off, just stick a small flat head screwdriver in the joint hole and lever up.

Cap is all that's required. No need to depressurise the fuel rail at valve in engine compartment.

Anyone had a problem with the engine missing after the Fuel Filter change?

Changed mine the other day, had some missing, CEL, but cleared up after driving it a bit, and cleared the codes with my reader.
Now if I let the car sit overnight the thing misses again, CEL, and does this until the car has run for a few minutes?
Could it take this long to purge the fuel lines?

Glyn, Todd?????

By the way, those clamps are called "Oetiker Clamps", and you can buy the kit with a bunch of different sizes and the pliers for about $50. online.

Thanks,
Dave

The filter includes the fuel pressure regulator. Hope you have not got a bad one. Hope you did not disturb dirt that might have got to the pump. Would seem unlikely.

Thanks Glyn,

I was afraid that the filter had the regulator in it.
Was okay this morning, will give it another day or so before I call SSF to see about them giving me another filter.

Thanks,
Dave

same happened to me after a fuel filter change. Left it idling after the change then left for an errand and started missing. Gave me a bank 1 cylinder code ( iirc correctly). Cleared it and turned on just fine after ward

Anyone know what size clamp is used on the fuel hoses?

Thanks!

Hey guys dont use the Purolator brand fuel filter.. Mine crapped out after 2 months or so and gave me all sorts of problems. New oem filter solved it all.

Now I'm looking forward to a fuel filter replacement, but didn't realize they were that expensive, even here in Germany. I'm hoping I can find a good quality, lower price replacement.

Glyn M Ruck

sk - Be careful - Buy the genuine article. It contains the fuel pressure regulator & we have had trouble with aftermarket units causing low fuel pressure with resultant poor running.

sknight

Thanks. I'll look for the oem replacement, since the dealers are nuts about pricing. Luckily, for items like this, we can get the Mann replacement...

Or maybe it's just not worth it. They last a long time anyhow...

M.L.X.

what about Bosch?

I have one I bought while back sitting here that I was planning on using on my replacement(which should be coming up soon)?...

thanks.

Bosch stuff is iffy in the US due to licensing their names. You see Bosch, but it might be champion or whatever other company paid to use their name for the filters.

Seriously?
I've done mine twice, both times with Bosch.
No problems so far.
I mean they INVENTED EFI.
I can't imagine they can't make a proper fuel filter.
The Knekt one is what the dealer sells.

You're not reading my post properly, and I couldn't care less if Bosch invented anything. First thing is they have MASSIVE quality control problems with the stuff they actually make, then in the US, such maintenance items aren't even made by, nor even overseen by them- they license their name to third parties to produce with no involvement by them at all. The last visit I made to the US, I checked out the Bosch filters at Autozone- the regular Champion garbage and very different from what I see here. The Autozone showed me the boxes it came in- source was somehow related to both Purolator and Champion, and the filter was identical to the ubiquitous Champion type, but more expensive.

What you get from Bosch depends on your local market and you have to go on a case by case basis, as with anything.

PS- it was not invented by Bosch.
