Fuel filter
 

My ML has just reached 65K, and am wondering if its time to have the fuel filter replaced. What about the air filter?

Yes, both are due at 60,000 or 4 years. The fuel filter will require modifications, a longer filter has been introduced which will require different hoses in the area of the filter. The filter is a little pricey, due to the fact it's also the fuel pressure regulator (returnless system).
To do the modification they/you will need to remove the left half of the rear seat and remove the lid above the fuel pump, once this is done it's fairly easy. I believe in our shop we quote 1.5 hours to do this job.

Gilly,

My fuel filter (new fitment) squeals like crazy and is quite embarrassing.

Thoughts?

I've heard of this happening, I think we had one in the shop doing this as well, I don't recall working on it myself. At any rate, the filter is defective and should be covered under spare parts warranty.
