ok thanks. That is the one I was seeing online 65-73 Mustang. I appreciate the help. I am driving to get the tank defueled as much as possible and am going to change it out next week. I have these brand new SpeedHut gauges that are working flawlessly and the fuel level is the only thing left to correct. When I restored the Jeep the old float was filled with fuel and I bought a replacement sending unit from OMIX. It read correctly for a week or two and then went to empty all the time, been like that for 7 years now.
