When does a fuel gauge show half a tank?
When the damnd thing is empty! I just brought another G and after 320 miles it still showed Half a tankand it wasnt cos its economical. Anybody know why?
Mine shows half a tank at 250 miles and is empty by 350.... The first time I drove it I thought "Wow! This thing is good on gas...." So I guess a half isn't always what it seems.....
Now the guys at the petrol station always state how suprised they are that it takes £60+ to fill the tank.... :(

No idea why,,,
did you find out the hard way?... Hope you weren't to far from a station..
The tank size is 95 l. I regularly take mine to 85 L. My guage is shot too. It reads 1/4 empty and then when the warning light comes on (20L left) the stupid thing jumps to half again. I rely on my trip meter and warning light more than the guage. I regularly get 460 m/ 85 L.
I believe the sender in the tank gets dirty and sends incorrects info to the guage. Almost £200 for a sender so I'll stick with the trip meter

My G shows empty at 320miles ish and I only ever manage to get about 60ltrs in it so I think the 460 gs only have 70ltr tanks.
I wouldnt advise running down to empty you tank though as they build up silt, rust and water and you may end up causing problems. Also they are not the easiest things to bleed once empty well at least mine wasnt but i am not sure whether the 463s self bleed.
Pretty much every 460 I have had has had fuel guage issues.
Anybody know if it is possible to clean the sender unit rather than having to replace?
Thanks

Wow, 460miles. I'll need to double check how many litres my 300GDS takes, but I seem to recall that when I fill it up from below the E line it is around 70-75 litres. (takes about £60 to fill) I doubt if I could get much more than 375 miles out of it too; as usually it falls short of 350.
you can clean the sender
you have to remove it from the top of the tank inside the back
its a long tube undo the nut at the bottom
hold the top pull off the white plastic bottom and tube DO THIS CAREFULLY
you see two thin wires DO NOT BREAK THESE WIRES OR MAKE THEM LOSE
the sender moves up and the larger tubes clean the tube make sure the sender moves free and the thin wires are tort

Hi
I replaced main and both saddle reserve tanks along with a new sender a couple of years ago. It still shows full after about 150 miles of driving then falls quickly unti the reserve light shows at about 330 miles. Puzzled me too. It's only when you realise that the sender is in the main tank and only indicates the level of that tank. So in effect the saddle or reserve tanks have to empy first before the guage indicates any drop in fuel level.

From driving trucks with 2 tanks my experience was that I had to fill both then back to 1st to top up cos the diameter of the connecting pipes meant they took a while to balance so with 2 auxilliary tanks you probably never manage to actually fill them as you only have 1 filler as it were unless you take a few minutes to squeeze it in.
I first discovered this problem some 5 miles after stopping at a motorway service station in while holidaying France and deciding not to refuel, as I had apparently still half a tank left....
Well, a visit to the dealer, new pumps, and a new sender have not cured the problem.
But I have read on other MB forums that a common fault is a hairline crack in the soldering of the dash instruments circuit board. This will be the next thing to check.
(BTW the 463 standard tank is 95 litres including the 10 litre reserve)
I did once wonder whether the feed and return lins to he tank may have been crossed.
Need to replace Fuel Gauge or Sender which is fitted in the Tank for my 300 Gd, kindly advise from where can i get this part.
Contact information would be appreciated.
no I sussed it before I ran out.It only took 60 litres to fill though and my 280 gel takes 85 liters when running on fumes so can only assume that it wasnt empty.
Any ideas how many liters the 1992 300gd takes?
I may have to find out the hard way with a gallon in a can in the boot.
