I'm in need of a Fuel tank sending unit for my 52' Cadillac. Please don't get confused with a fuel pump. I need the float assembly itself? Feel free to email me or give me a call if you have one or know where I can get one. My email is Moberghearse@yahoo.com and phone# 218-236-8674 (ask for Jeremy)
Try John Wolf and Co. Willoughby, Ohio 440-942-0083. He put together one for my '57. All he needed to know was the amount of vertical travel of the float. If you have your original he can rebuild that or look in your shop manual, if you have one, for the float info.
