Removing the in tank fuel filter

Look under your car and see where the fuel line exits the tank. If you can get a wrench with big enough opening or a socket that fits the filter, go for it. I suggest you do a couple of things before starting.

1. Call "**************" at (800 513-5797) and see if their "Fuel Tank Screen Replacement Kit" will fit your vehicle. It comes with a special tool created by them for the specific purpose of removing the tank filter.

If the one they carry will not work with your vehicle, buy the tank filter, measure it for size and see if you can find a wrench or socket to fit it.

2. I also suggest that you buy their "Gas and Diesel Fuel Hose Clamp Off Tools" to avoid spillling diesel fuel all over yourself and the ground (or floor). In addition, suggest you buy a few feet of clear plastic tubing from lowes or similar-type store (hardware). Make sure this hose will fit snugly onto your fuel line, which is probably 5/16 inch. You will also need a container to hold the fuel you will draining. To be on the safe side, I suggest you buy one of the five gallon tanks that you can pick up from a tractor-supply store. These are the old fashioned metal containers and can always be used as a spare fuel can.

Once you have lifted your car in the air (best way, I think) or mounted it on jack stands, you are ready. Clamp off the filter line and disconnect the end of the line from the metal line. Next, push the end of the fuel line into the plastic line you picked up from Lowes (or whomever). Point the other end of the fuel line into the can and un-clamp the line. You fuel will start to drain into the can and should not have wasted any on yourself or the floor or ground. Hopefully you have ran your car low enough so that you five-gallon can will be big enough to hold it all. Even with my low-fuel light coming on, I still had about five and half gallons of fuel left in my tank. Even so, it was just a simple matter of re-clamping the line and getting another container to hold the additional fuel. Once the tank is empty, use the tool from Mercedes Source or the large socket you acquired to remove the filter. Put the new filter on, put on your (new) fuel lines and pour your fuel back into the tank. I would also suggest (if you have not done so recently) that you do a diesel purge and change out your pre-filter and main canister filter also. Then use the hand pump located on the Injection Pump's "lift pump" to purge the system of air. Once you see the prefilter full of fuel, start your car. If the car does not start, you will have to do some more purging of air. In rare cases, you might have to crack open you injection lines to get all of the air out of the system.

Hope I have been some help.
