'82 w123 240D fuel sending unit "submarine"
I replaced the fuel sending unit on my w123 240D. The old
one came out easily except that it was missing the outer tube and the bottom retainer or "cap". I then heard the tube hit the bottom of the (full) tank as I removed what was left. I guess the tiny nut and bottom retainer (or "cap") had come off some time earlier and the outer tube was held in place by (who knows what?) until I came along and tried to remove the assembly. The tank is mounted vertically behind the back seat. I have easy access to the sending unit after removing the first aid kit tray. So my question is, are there any ideas on how to easily and safely remove this tube from the depths? It rumbles around in the tank on certain roads. My ideas are: (*) When tank is empty, use a hanger and flashlight to fish it out. Don't want any sparks though. Maybe fashion a wooden tool. (*) Use a magnet on the end of a rod of some sort (wood?). Not sure what the tube is made of. Aluminum? Might not work. (*) Remove gas tank and remove the tube. Jeff

removing tube from tank
Too bad that fell in there!!!
Your first idea was best...just fish it out with a couple of coat hanger wires...although you might find it tough to orient it for removal and grasp it tightly at the same time. Try suspending a strong magnet to grab it. Dont worry about sparks...Diesel fuel has a flash point of about 150 deg. F ...this means that at ordinary temps (70 to 90 deg. F) the liquid will not give of enough vapors to reach the flammable concentration. Because of this, diesel fuel is much much safer than gasoline. I wouldnt even drain the tank...just fish it out. good luck |
