My instrument cluster was very faded, the needles were yellow and the odometer stopped working. Everything else works perfectly. So i got a 90's model instrument cluster from a junk yard and put it in. Much brighter orange needles, no sun spots, odometer works however the ONLY problem is the gas gauge doesnt work. My mom has a 91 300E and has the exact same problem. THe needle works from full to half then at half it stays around that area and goes lower and higher intermittently. The gas light works.

My question is, is there a way to fix it. Also i have 2 other instrument clusters for parts and i tried to see if i can take out the gas gauge from one of them and its tricky. Its attached to the whole left side. It has rivets and i would have to take the needles off because they're yellowish (Which is hard apparently from reading other forums). ANy suggestions, opinions????
