I'm having issues with the fuel gauge not reading correctly on my '40. It's converted to 12v, but it has a Mustang style voltage reducer feeding the fuel gauge. If I ground the sending unit wire it reads full, so I thought the sender had failed. I bought a reproduction Vintique 6v sender since I'm still using the original gauge, but on a full tank it still only reads about half full. Any ideas on what's going on here?
