Veggie tank faulty Sending Unit

i'm having some trouble with my sending unit in the veg tank. when the gauge reads half it is actually empty. does anyone have experience with this problem? i'm sure i could take the tank out and clean the unit, but i'd rather not. maybe i could fill the tank with diesel or biodiesel and that would clean out the gunk in the sending unit. thanks matt

SVO Fuel Conversion Specific Aid

Will not power past 75 mph! Slight loss of power uphill.

Hello, I have a 1984 300sd with 230,000 miles. Did alot of work to it, thanks to Mercedes Source. Anyway, did valve adjustment, compression test (pressure max out close to 400). Changed injector nozzles to Bosios. Engine does not knock and is a bit smoother and responsive. Problem: pedal to the floor on highway and will not get past 75 mph?! Sometimes loss of power up hill. Have not changed the fuel lines from the tank. Is this the possible culprit? Thanks, RP.
