Whats up people. So my 94 940 (bosch system) fuel gauge has never worked properly since i got it. I recently swapped out the fuel sending unit becuase the old one failed (didnt ohm out). like i said when the gauge works it now reads correctly. Im thinking its the gauge? The wires to the gauge ohm out(from the back in the trunk), so maybe a bad ground? any suggestions? also if it came down to it would i be able to just replace the gauge or would i have to the whole cluster? And any info on how to get to it (taking off the dash), would be awesome. thanks
