don't have a 3/4" deep socket, and my box end/open end wrenches can't get a good grip on it. my 1 13/16" can grip the screen with the hose fitting still on.

The hex on the screen is thin. Look at the end of your socket where it will fit over the nut and you will see a champer that needs to be removed (faced in a lathe) for it to fit up on the nut. I just cleaned two of these screens so I modified the overall length of the socket and turned the upper portion so that a pipe wrench would bite it better. It was TIGHT and difficult and will dump a lot of diesel on you for your troubles. The next one that I do will have the car up on its side and the fuel sending unit removed so that I can pump more of the fuel out.
It will run better after the screen is cleaned. My screen was cloged with a substance like mud with sand but the rest of the tank looked clean.

After spending the past few hours trying to get the 46mm to turn, I have come to realize that yes, that chamfer has to go. Unfortunately I'm not sure I can get on a lathe until March, and the car is laid up until then. Might be time to go to a pro machine shop.

Take the return line from under the hood and route it into a five gallon container.

Start engine.

Go back inside house for a cup of coffee.

Return to vehicle.

Turn off ignition (engine is not running due to lack of fuel).

Perform tank screen removal.



.............credit to Kerry for the solution.

If you want to send it to me with return postage I will cut it down for you. Most sockets are HARD but will cut with carbide. Send me a PM

Won't do it. You will still take a diesel bath. The filter plugs up from the bottom and is is solid leaving as much as three inched of fuel that will not come out of the line. I have had a pump sucking on the line for several hours and when I removed the pump a small trickle would return out of the line. Try it and you will see what is going on.

Look at the picture that I attached earlier.

Agreed..........if the screen is that bad..........you need to disconnect the return line, quickly attach a short hose, and run it into a five gallon container.

Just use a 4" hand grinder to gnaw off the small chamfer on the socket...
Harbor freight about 20 bucks...go slow and you wont overheat the socket...
You could chuck the socket in a drill with a proper necked down extension and grind away...
Sort of a bad, bailout-economy, po-boy milling machine....

I guess that you could do it that way if you want but then again why not just use a chisel to drift it loose?

I removed one with a pair of slip joint Knipex plumbing pliers at a Pull-a-part...took a real diesel bath on that one...
Just a thought on the socket chamfer removal with a grinder....
I had to do that with a 30MM socket to get an electric hot water heater element out...
They have that thin hex area also....

Looks more like a check valve. Too small to be more than a strainer.

Def. not an MB item though, Germans wouldn't put something at an odd angle like that.

Yep, factory. Been there, confused by that. Found the answers in here via a half hour or more of searching. For you it will be easier to find.

Search using my user name as author and hmmmmmm.... tank? to find my thread about dealing with my tank issues. Was not that long ago. Month, 6 weeks? Your answer is in there.

Do you want your socket turned this much? I turned this socket so that a bar wrench and an adapter would fit between the axle shaft and strainer(1/2 to 3/4). I also turned the upper portion so that a pipe wrench would grip it if necessary but at this short length you would have a short throw to turn it. The socket will still fit the fuel gage and block heater this short.
Let me know, I should get it Tuesday and have it back on the way to you the same day.
Robert

PS Only use a 19mm box end to remove the fuel line from the strainer.

The socket is on the way back to you. I have turned it and shortened it to fit with a adapter and bar wrench. Put a box end over the fuel hose and use a cheater bar to remove the 19mm fuel hose fitting. Look up at the strainer to see if the rubber that the tank sits on will interfere with the socket, get it out of the way. It might be easier to have the wheel off and two people.
Let me know if I can do anything more to help.
