Want to change my fuel filter when changing my fuel Pump and don't want to order the 3 new fuel lines needed to upgrade the fuel filter if I don't need them.
According to my Vin# I do need the upgrade, but I am not the org owner and maybe it was done in the past??

Question.
How can you tell if the upgrade has been done or not. I want to take off the rear wheel and take a look, but I have no idea what to look for in order to determine if it needs an upgrade with new 3 fuel lines or not.

If it was done at a dealer you can ask any US MB dealer's service department to look
up your VIN and see if a dealer did it.

The only other way is to compare the filter on the truck to pics of the new filter. In order to
do so you will have to pull the left rear wheel off and remove the wheel arch liner.
You will see the filter lodged to the left of the rotor on the frame.

+1 on checking VMI.

Most characteristic in upgrade is fuel line loop 3. In original setup fuel filter was shorter and connector 8 of fuel feed line 4 was connected directly to filter outlet. With larger filter it would be impossible to connect feed line without kinking it. Hence need for a loop.

To make job less frustrating get a pair of pliers made by Klann. Amazon.com: Klann Tools (KLA0121-38) Fuel Line Pliers: Home Improvement: Reviews, Prices & more

Those Klann line pliers are amazing. I got them for $50 shipped. Best $50 I spent on a
tool in a long time.

I took off the tire and was able to see the part # on the filter that is on the truck now. It is part # 163 477 05 01

I am not sure, but I think I need to upgrade to the 3 new lines. I am going to call the dealer on Monday and hopefully they will be able to tell me for sure.

Also, forgot to mention that the fuel filter I have on the truck right now with part #163 477 05 01 is 6 inches long.

If the new filter is longer than 6 inchs. I don't see how it can possibly fit in the same space as the old filter???

163 477 05 01 is newer larger filter. It was replaced with 163 477 07 01 with no change in form or shape.

So, if it's the newer larger filter - Do I need to update the fuel lines? I am not sure which fuel lines need to be replace or added when I go to change filter 163 477 05 01 with filter
163 477 07 01
