Ok guys before you purchase a new fuel sending unit try and clean the electrical connection on top of the unit first. Don't make the same mistake I did, and purchase a new VDO sending unit which didn't solve the gauge Fluctuating issue. I took the old one apart, and cleaned it up well put it back together and used a 220 grit sand paper to clean the electrical connection on the sending unit. It works perfectly fine now.BTW it's a 1995 E320
