I've yet to find any sender worth a damn on these cars. Even tried one from a gasser W116 (280SE). I've made sure my Low Fuel light circuitry and light are working, which has been very reliable, and go by that. Oh, and always carry 2.5 gals of fuel in the trunk in an old Amzoil ATF bottle....

I am still accumulating miles on the '77 240D. It still falls on its
face every once in a while, but is back to normal on the next start. I
have collected almost everything needed for a major run-in with the engine.
Fast glow plugs
Valve adjusting wrenches
Monark injectors
Return hose and end
Finished replacing the accessory belts, tightened the steering gearbox,
replaced the fuel sending unit with a somewhat better one, repaired the
turn signal stalk that doesn't stay engaged by using a dental drill to
grind out the detents.
She's gotten me to work every day, hauled trailers full of limbs and
wood. Been paying its way.
I took my original one apart and cleaned it with some improvement, but not enough to be sure of any sort of accuracy. I bought one on Ebay that was supposedly "renewed" but last night at 0 dark 30 in the morning, I found myself walking down a back road a good two miles from town. The gage insisted that I have a quarter tank left. Somebody lied.
As long as I have the old one sitting here, I am going to take it apart one more time and take a stab at bending the contacts on the float.
This looks like the best instruction I've seen.
