I changed my tank screen the other day after work. The whole operation took an hour. I was able to get a 1-13/16" socket at NAPA for $14.00.

Here's what you do if it's so cold your diesel fuel gels. Smear some on some toast and stay inside until it warms up outside.

yep, i got the 46mm socket (plus adapter :B ) for about that amount.
from northern tool 9.99 plus 3.99. but of course i had to drive all the way out there. it's ok though. i'm fixing my flex pipe (after the turbo to the exhaust). it was cracked so i took it off (cant drive the car without exhaust (even though it would be cool to make it sound like a freightliner......and definitely can't drive it without fuel supply.....


but, all in all...very quick procedure, just make sure to burn as much fuel as necessary first (i ended up getting 5 gallons out, and the last of it was DIRTY). i would recommend all to do the same thing if you don't know when it was done last.

Another DIY with additional pictures

I did a "screen job" on my 1985 300D W123 today. Rather than describe the whole procedure once again, I'll simply throw in a few notes, plus my pictures.

After chocking the front wheels, I jacked up the rear and put the car on my cheap sheet-metal jack stands. (Yes, I'm gonna buy good ones.) That gave me enough room to crawl under. The first thing I did was to put a clamp on the feed hose (new hose, original replaced last year with something that tolerates biodiesel). [Clamp: Lisle Tools #22850 "Hose Pincher," package of 2, about US$7]

When you remove the rubber fuel hose from the metal fuel line (that runs to the lift pump), the metal line will sit there and drizzle fuel all over, making a mess and giving you a big air bubble in your filters, possibly starving the engine of fuel when you try to start it later. To prevent this, I was ready with a rubber cap that went on the line as soon as the tank hose came off.

I had allowed the fuel tank to get down to the "R" mark on the gauge, so there wasn't too much (B100 biodiesel) to drain. The fuel was drained into a series of 2-gallon bottles (originally sold with cat litter in them) and my trusty used-to-be-red 5-gallon metal fuel can. I was able to remove between 5 and 6 gallons, so I now know how much is left when the gauge gets to "R." This is confirmed by the fact that, if I go fill up the 21 gallon tank at this point, it takes about 15 gallons. I put a piece of clear hose over the tank hose so I could watch the fuel flow and get it all into the catch bottle.

The hose fitting takes a 19mm wrench. I thought it was all one piece with the hose and pulled it with the hose still attached.

To remove the screen, I used a 1-13/16" socket from Northern Tool along with a 1/2"-to-3/4" adapter from the same place instead of the factory 46mm socket. Cost including shipping was about $20. It is a tight fit to the axle, as you can see, and a 3/4" drive bar would have been better, but I don't own one. Note that this socket also fits the fuel quantity sender that mounts in the top of the tank. Do be careful, shiny metal tools covered with biodiesel are unbelievably slippery.

The empty hole in the tank will drizzle fuel over the axle. (I hope my CVJ axle boot rubber material will tolerate biodiesel.) I wiped it off as well as I could; next time I'll cover the axle with plastic sheet. I had a pan underneath and collected only a cup or two in miscellaneous drips and dribbles. I was surprised and happy to see that the fuel was all clean and free of crud. Sticking a finger up through the hole and rubbing the inside of the tank brought out only a little black, probably left-over dirt from 207000 miles of petroleum-based diesel fuel.

The screen too was very clean and there was really nothing to do. I discovered that the o-ring seal, although flattened a bit, was still pliable, so I didn't replace it. (It probably had been replaced by a PO -- I can't imaging a 22 year old o-ring being that good.) And a very good thing, too, for I had failed to buy a new one. The o-ring fits in a groove machined in the screw base of the tank screen. If you remove the o-ring, don't forget to put it back!

That's about it. Reassembly went smoothly -- just be careful not to cross-thread the screen in its hole. I had a little trouble getting it started, while biodiesel dribbled down my rubber-gloved hands, but eventually got it right. I didn't even make much of a mess, how unusual!

I am thoroughly confused. Is the screen inside the tank or not? I have a 1987 300TD Turbo wagon, and the pics here do not match up to my car. These pics look like the screen is in the chasis of the car. My fuel tank is external, right in front of the rear muffler, and is held in place by 6 -8 bolts.

I am removing the fuel tank today to find a leak, and want to change the screen while I have the tank out.

That is because the car in the pics is a W123. Yes, the screen is inside the tank.

You have a W124 and I believe the wagons tank is different than the sedan.

Viet Vet,
Welcome to the forum !!!
We all hope that you get all the help you need for your car on here!!

The tank screen is held in by a large allen bolt that looks like the drain on the underside of your tank. no need to remove the tank to clean it. You can remove the the allen bolt to drain the tank before you remove the tank. Your leak may be a damaged hose & not the tank.
