Hi, all - the fuel gauge in my '69 GS 400 is stuck way past full. From all I understand, it's probably a short somewhere, which is what I'm going to check first. I've read up on the previous posts on this topic, although any car-specific advice would be most appreciated. All of this leads me to the next questions, which are a) where does one obtain a replacement fuel sender unit and b) how does one go about removing the old and installing the new? Any help is, as always, appreciated. Thanks- John
